Polymer
In this activity, students will create their own bouncy balls. Three types of balls will be created, using different combinations of water, cornstarch, borax and white glue. In all of these methods, a polymer (a chain of repeated units) is created and molded into a ball shape. Although each type look similar, they have different physical properties, which students will observe while testing which type of ball bounces better.

Plate Tectonics Day 2
(The different ways plates move)
Seismologists have studied how wave energy travels through the different layers of Earth. Waves have characteristics: frequency, wavelength, amplitude and speed. During an earthquake, energy is released into the Earth as: Primary waves, Secondary waves and Surface waves.
Major geological events, such as earthquakes, volcanic eruptions, and mountain building result from these plate motions.
Divergent Boundary: Boundary between two plates that are moving apart or rifting
(Divide) plates split; hot molten rock from the mantle rises, cools and causes the floor to spread.
Ex.#1 The Mid-Atlantic Ridge Ex.#2 Iceland
There are three types of Convergent Boundaries:
Convergent two continental plates crash into one another and form mountains over millions of years.
(Collide) Ex.#1 The Himalayas Ex.#2 Appalachians
Convergent oceanic plates collide with continental plates, and slide beneath them creating trenches
(Subduction) and/or volcanic arcs. Oceanic plates are more dense than continental plates so
oceanic plates slide under continental plates
Ex. Mt. St. Helens
Convergent oceanic plates collide with oceanic plates, the older, more dense plate slides beneath the
(Subduction) newer, less dense plate and forms trenches and/or island arcs.
Ex. Aleutian Peninsula of Alaska
Transform two plates slide/grind together past each other often causing earthquakes.
(Slide Sideways) Ex. San Andreas Fault (California)
Answer the following questions in your notebook.
Why do earthquakes in other countries seem to cause more damage and casualties than earthquakes in the US?
What can Americans do about it?
Structures are built stronger
Hotspots: hot material rises up through the mantle, heats up the lithosphere and forms a volcano.
Once the plate passes over this hotspot, the volcano becomes inactive.
Ex. Hawaiian Islands
There are worldwide patterns to major geological events (such as earthquakes, volcanic eruptions, and mountain building) that coincide with plate boundaries.

Plate Tectonics-Introduction
6.E.2.2
The earth's plates sit on a dense, hot, somewhat melted layer of the earth. The plates move very slowly, pressing against one another in some places and pulling apart in other places, sometimes scraping alongside each other as they do. Mountains form as two continental plates, or an ocean plate and a continental plate, press together. There are worldwide patterns to major geological events (such as earthquakes, volcanic eruptions, and mountain building) that coincide with plate boundaries. Lithospheric plates on the scale of continents and oceans constantly move at rates of centimeters per year as a result of movements in the mantle coupled with characteristics of the plates themselves. Major geological events, such as earthquakes, volcanic eruptions, and mountain building, result from these plate motions. The crustal plates range in thickness from a few to more than 100 kilometers. Ocean floors are the tops of thin oceanic plates that spread outward from mid-ocean rift zones; land surfaces are the tops of thicker, less-dense continental plates. Earth is made up of 4 different layers: inner core, outer core, mantle, crust. Seismologists have studied how wave energy travels through the different layers of Earth. Waves have characteristics: frequency, wavelength, amplitude and speed. During an earthquake, energy is released into the Earth as: Primary waves, Secondary waves and Surface waves. 2013
There are two types of Crust.
Oceanic Crust- crust under ocean
Continental Crust-crust under land
The lithosphere sits on top of the asthenosphere.
Continental Drift is the theory that all continents were once joinedtogether in one landmass.
This theory was named Pangaea.
Fossils provided evidence for the theory of Pangaea.
The lithosphere is broken into separate sections called plates.
The geological theory that states that pieces of Earth’s lithosphere are in constant slow motion, driven by convection currents in the mantle is Continental Drift This theory states that tectonic plates are moving approximately 3 cm (1 inch) per year.
Hot magma in the mantle heats up and cools.
As it heats it rises, and as it cools it sinks. This is a process called convection currents.
Please use the term convection currents in a sentence.

Earth's Magnetic Force
Homework Due-None
Classwork-
Earth’s Magnetic Field
In this activity you will explore magnetism. The shape and size of this force is invisible, but through this experiment you will be able to see and describe it.
What you do:
1. Place your Earth model with magnet flat on your tray.
2. Sprinkle just a few iron filings onto the plastic over the magnet.
3. Tip your Earth model with magnet a little and watch some of the iron filings slide downhill. Answer this: Did all the iron filings slide down? Why or why not?
Sprinkle more iron filings onto the model, trying to sprinkle them evenly over the whole model. Make sure there are not so many that you can’t see the paper.
4. Observe the iron filings. In the space below draw an illustration of the pattern that the iron filings make.
5. Clean up your station.
a. Carefully take your Earth model with magnet to the designated bucket.
b. Curl the paper so the model fits in the container with the opening to the paper on the top.
c. Place your hand in the plastic to separate the plastic from the magnet to allow the remainder iron filings to release.
d. Take the entire model out of the bucket and all iron filings should be off.
e. Place the magnet back inside the page protector.
f. Return the model to your station.
g. WASH YOUR HANDS
6. Using the observations that you made during this lab, answer the following questions:
a. Explain the pattern of the iron filings.
b. Why did they create this pattern?
c. How does the pattern of iron filings show a magnetic field?
d. What could you do to determine which end is the North Pole? (without looking for the N or S on the magnet)

Layers of the Earth
Objective: Students will investigate the composition and makeup of the Earth’s layers and be able to explain how best to model the composition of each layer by using a CER planner to organize their information.
Warm Up Part 2:
Eventually, the earth's surface ____________ and took a form more familiar to us. Today, even from space, we can see only a small part of the earth what lies underneath our planet's surface remains hidden from view. In a way, looking at the ____________ is like looking at the shell of a hard-boiled egg. The shell is only a very ______ covering, but if we cut open an egg. We can see that beneath the shell are several _________. Inside the egg is yellowish yolk and the yolk is surrounded by white. Like an egg, the earth consists of several layers. Even though we can't cut open the earth, scientists have been able to determine much about what is under the earth's surface. Like the shell of an egg, the earth's _________________ layer, called the crust, is very thin, on average, only about ten to twenty kilometers thick. Beneath the crust is a layer of ____________, heavier material called the mantle. The mantle is the ____________________ part of the earth. Scientists think the mantle is made up of heavy rock, containing metals like magnesium and iron. The core is at the___________ of the earth. It consists largely of ____________ and____________. The very center of the core is the _______________ part of the earth with temperatures reaching about ___________ degrees Celsius.

(The different ways plates move)
Seismologists have studied how wave energy travels through the different layers of Earth. Waves have characteristics: frequency, wavelength, amplitude and speed. During an earthquake, energy is released into the Earth as: Primary waves, Secondary waves and Surface waves.
Major geological events, such as earthquakes, volcanic eruptions, and mountain building result from these plate motions.
Divergent Boundary: Boundary between two plates that are moving apart or rifting
(Divide) plates split; hot molten rock from the mantle rises, cools and causes the floor to spread.
Ex.#1 The Mid-Atlantic Ridge Ex.#2 Iceland
There are three types of Convergent Boundaries:
Convergent two continental plates crash into one another and form mountains over millions of years.
(Collide) Ex.#1 The Himalayas Ex.#2 Appalachians
Convergent oceanic plates collide with continental plates, and slide beneath them creating trenches
(Subduction) and/or volcanic arcs. Oceanic plates are more dense than continental plates so
oceanic plates slide under continental plates
Ex. Mt. St. Helens
Convergent oceanic plates collide with oceanic plates, the older, more dense plate slides beneath the
(Subduction) newer, less dense plate and forms trenches and/or island arcs.
Ex. Aleutian Peninsula of Alaska
Transform two plates slide/grind together past each other often causing earthquakes.
(Slide Sideways) Ex. San Andreas Fault (California)
Answer the following questions in your notebook.
Why do earthquakes in other countries seem to cause more damage and casualties than earthquakes in the US?
What can Americans do about it?
Structures are built stronger
Hotspots: hot material rises up through the mantle, heats up the lithosphere and forms a volcano.
Once the plate passes over this hotspot, the volcano becomes inactive.
Ex. Hawaiian Islands
There are worldwide patterns to major geological events (such as earthquakes, volcanic eruptions, and mountain building) that coincide with plate boundaries.

Plate Tectonics-Introduction
6.E.2.2
The earth's plates sit on a dense, hot, somewhat melted layer of the earth. The plates move very slowly, pressing against one another in some places and pulling apart in other places, sometimes scraping alongside each other as they do. Mountains form as two continental plates, or an ocean plate and a continental plate, press together. There are worldwide patterns to major geological events (such as earthquakes, volcanic eruptions, and mountain building) that coincide with plate boundaries. Lithospheric plates on the scale of continents and oceans constantly move at rates of centimeters per year as a result of movements in the mantle coupled with characteristics of the plates themselves. Major geological events, such as earthquakes, volcanic eruptions, and mountain building, result from these plate motions. The crustal plates range in thickness from a few to more than 100 kilometers. Ocean floors are the tops of thin oceanic plates that spread outward from mid-ocean rift zones; land surfaces are the tops of thicker, less-dense continental plates. Earth is made up of 4 different layers: inner core, outer core, mantle, crust. Seismologists have studied how wave energy travels through the different layers of Earth. Waves have characteristics: frequency, wavelength, amplitude and speed. During an earthquake, energy is released into the Earth as: Primary waves, Secondary waves and Surface waves. 2013
There are two types of Crust.
Oceanic Crust- crust under ocean
Continental Crust-crust under land
The lithosphere sits on top of the asthenosphere.
Continental Drift is the theory that all continents were once joinedtogether in one landmass.
This theory was named Pangaea.
Fossils provided evidence for the theory of Pangaea.
The lithosphere is broken into separate sections called plates.
The geological theory that states that pieces of Earth’s lithosphere are in constant slow motion, driven by convection currents in the mantle is Continental Drift This theory states that tectonic plates are moving approximately 3 cm (1 inch) per year.
Hot magma in the mantle heats up and cools.
As it heats it rises, and as it cools it sinks. This is a process called convection currents.
Please use the term convection currents in a sentence.

Yellow
Green
Blue
Indigo
Violet
Adding colors
White light can be divided up to make separate colors. These colors can be added together again.
The primary colors of light are red, blue and green
Seeing color
The color an object appears depends on the colors of light it reflects.
For example, a green book only reflects green light.
A pair of purple trousers would reflect purple light.
(and red and blue, as purple is made up of red and blue).
A white hat would reflect all colors of visible light.
If we look at a colored object in colored light we see something colored.
In red light, your shirt will look red.
In blue light, your shirt will look blue.

Do you choose black asphalt or white concrete? Explain your answer.
Classwork-
Light and Sight
The sun is a major source of energy for changes on the earth’s surface.
The sun loses energy by emitting (giving off) light.
A tiny fraction of the light reaches the earth, transferring energy from the sun to the earth.
The sun’s energy arrives as light with a range of wavelengths, consisting of:
Electromagnetic radiation in this range of wavelengths is called visible light.
Human eyes respond to only a narrow range of wavelengths of electromagnetic waves-visible light.
Differences of wavelength within that range are perceived as differences of color.
Visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) human eyes.
The structure of the human eye can detect many colors in visible light that are reflected by objects.
The Parts of the Human Eye
Cornea – a transparent membrane that covers the eye
Iris – circular band that controls how much light enters the eye
Lens – A transparent tissue that bends light passing through the eye which bends light and helps you focus on an image
Pupil – The hole in the center of the eye which allows light to pass through
Retina – layer of tissue on the back of the eye that has cone and rod cells which gather information
Optic Nerve – Begins in the back of your eye and is the connection to your brain
The Process of How Humans See
Step 1 Light waves bounce off objects.
Step 2 Light enters the eye through the cornea.
Step 3 Light continues through the pupil which is controlled by the iris.
Step 4 Light passes through the lens which refracts (bends) the light causing the picture to be upside down.
Step 5 The upside down picture travels to the retina which flips the image right side up.
Step 6 The optic nerve sends signals to the brain, which interprets the images.

1.Wave Definition—a disturbance that transfers energy from one place to another; Characteristics—energy travels entire distance, while matter does not; Examples—sound waves, water waves, light waves;
2. Drawings should show how a wave was created from up-and-down or back-and-forth forces.
3. Medium Definition—any substance that a wave moves through; Characteristics—all materials; Examples—water, the ground, a rope;
4. Notes: it is energy that is transferred in a wave, not the matter that the wave moves through. In some cases, kinetic energy is transferred. The medium of the wave only moves slightly, while the wave can travel great distances;
5. Transverse—picture:
Notes: wave in which the direction of travel is perpendicular to the direction of the disturbance; there is an up and down motion of medium; some examples include a rope and a water wave.
Longitudinal—picture:
Notes: wave that travels in the same direction as the disturbance; it has many bunched-up areas known as compressions; examples are sound waves and waves on a spring.
Section 1.2C Note Answers
1. amplitude, wavelength, and frequency
2. Crests are the highest points, or peaks of waves. Troughs are the lowest points, or valleys of waves.
3. Notes:
The amplitude is the distance between a line through the middle of a wave and a crest or trough.
The wavelength is the distance from one wave crest to the next.
The frequency is the number of wavelengths passing a fixed point in a certain amount of time.
4. The wave with a higher amplitude has more energy.
5. When frequency increases, there are more wavelengths per second, and the wavelength shortens.
On the other hand, when frequency decreases, there are fewer wavelengths per second, and the wavelengths are longer.
6. Amplitude is measured by determining the compression of the medium.
The frequency is measured by determining the number of wavelengths passing a fixed point in a certain amount of time.
For transverse waves, the amplitude is measured by determining the distance between the wave’s position at rest and the wave’s crest or trough.
The frequencies for both types of waves are measured in the same way.
7. Speed = wavelength x frequency
8. S= 2 m/s

Important Vocabulary Term Review
Thermal Energy: Heat energy an object has due to the motion of its particles
Kinetic Theory in Matter states that all of the particles that make up matter are constantly in motion.
Heat is transferred from one object to another in three ways:
Conduction Heat traveling through solids.
Two objects must touch or have direct contact.
As molecules heat up they move faster and expand.
Convection
Heat traveling through liquids or gases
As molecules heat up, the heat makes the molecules move more rapidly and expand.
Radiation
Release of invisible heat energy waves from the sun or fire.
No movement of molecules to transfer heat.
Feel warm without touch – heat radiates.
Conductors: Materials through which heat travels very quickly. Examples: Metal, water. Insulators: Materials through which heat travels very Slowly. Examples: Wood, Plastic, Rubber.
Heat: Total amount of kinetic energy of a substance.
Temperature: Measurement of average kinetic energy of particles. Measured in degrees C or F.
Thermal Expansion: As an object’s temperature increases as a result of the kinetic energy of its molecules increasing, they take up more space and the object expands.
Thermal Contraction: As an object cools as a result of the kinetic energy of its molecules decreasing, they take up less space and the object contracts.(gets smaller)
Thermal Equilibrium: (Balance of heat) When a hot object is placed in contact with a cold object, heat energy travels from the hot object to the cold object until both objects are the same temperature.
In what direction does heat flow? Heat always moves from hotter objects to cooler objects.
Energy can be transferred, or converted, from one form to another
Energy: The ability to do work.
The Law of Conservation of Energy: Energy can neither be created nor destroyed. However, it can be changed from one form to another.
Mechanical Energy (ability to do work): Energy of an object due to its motion or due to its position. kinetic energy (energy of motion) or potential energy (stored energy of position).
Electrical Energy: The movement of elections between atoms to produce electricity . Example: When an electrical source such as a battery or generator is connected in a complete circuit to an electrical device.
Chemical Energy: Potential energy stored in chemical bonds. Example: Food, Fire Cracker, Battery

When the water starts to move, the potential energy becomes kinetic energy. When the turbine starts to spin, the kinetic energy becomes a specific kind of kinetic energy called mechanical energy The spinning motion of the turbine is used to rotate a coil of copper wire between two opposite magnetic poles. This starts electrons moving down the wire. When the coil of copper wire rotates past the North magnetic pole, the electrons move down the wire in one direction. When the coil rotates past the South magnetic pole, the electrons reverse direction. This back-and-forth flow of electricity through a wire is called alternating current-otherwise known as AC. A device in which coils of copper wire are rotated through magnetic fields to generate electric current is called a dynamo.

The Law of Conservation
Energy can neither be created nor destroyed. However, it can be changed from one form to another.
Forms of Energy
Thermal (Heat)
Mechanical
Mechanical Energy-energy associated with the motion of an object. Mechanical Energy as the Ability to Do Work
- Mechanical energy is the energy that is possessed by an object due to its motion or due to its position.
- Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
- Objects have mechanical energy if they are in motion and/or if they are at some position relative to a zero potential energy position
Electrical
Electrical Energy Moving electrical charges that produce electricity and energy.
- Electrical energy is the movement of elections.
- Lightning and static electricity are examples of electrical energy that occur naturally.
- Science hasn't found a way to use natural forms of electrical energy, like lightning. Instead, we use different energy sources to create electrical energy by using generators and turbines.

Heat Energy
•Energy is what makes things happen.
•The movement creates heat.
•The amount of heat depends on how fast the molecules move.
•As the molecules move faster, they take up more space and make the object expand.
Conduction
•Heat traveling through solids.
•Two objects must touch or have direct contact.
•As molecules heat up they move faster and expand.
•When you touch one hot surface to another, the hot molecules bump into the other molecules which makes them start to move faster.
•An object gets hotter from the movement of the molecules.
•All solid objects conduct heat, some are better conductor than others.
•Metals are good conductors.
Convection
•Heat traveling through liquids or gases
•As molecules heat up, the heat makes the molecules move more rapidly and expand.
•Creates currents in liquids or gases – hot air rises and cold air sinks.
Radiation
•Release of invisible heat energy waves from the sun or fire.
•No movement of molecules to transfer heat.
•Feel warm without touch – heat radiates. •Radiators got their name from this type of heat.
•When the radiant energy from the sun hits the earth, the earth soaks up the energy and changes it into heat.
Balance
•Whenever a hot object is placed near a cold object, the hot object will transfer heat to the cold object until they reach a state of balance. •Balance happens when the temperatures of both objects are the same.
•The fast moving molecules mix with the slow moving molecules until they are all mixed and balanced.
Insulator- Does not transfer energy easily
Examples are wood and foam
Conductor-materials that transfer energy easily

KINETIC ENERGY: Energy of a moving object
More motion and mass = more kinetic energy
GRAVITATIONAL POTENTIAL ENERGY: Energy of an object placed above the ground
More height = more gravitational energy stored
Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed.
A system of objects may also contain stored (potential) energy, depending on their relative positions. For example, energy is stored—in gravitational interaction with Earth—when an object is raised, and energy is released when the object falls or is lowered. Energy is also stored in the electric fields between charged particles and the magnetic fields between magnets, and it changes when these objects are moved relative to one another. Stored energy is decreased in some chemical reactions and increased in others.

Caroline and her friend Rita are on vacation with Caroline’s family to the Great Salt Lake in Utah. On the first day of their trip, they raced down to the shoreline of the lake and rented a canoe. When they got to the shore line with the canoe, they stopped short in amazement. People were floating in the lake with their heads far out of the water, even though they weren’t making any swimming motions. They put the canoe in the water, got in, and started paddling. Almost immediately, the canoe tipped over. The water was not deep, so they up righted the canoe and set out again. The same thing happened. They never had this problem when they canoed on fresh water lakes.

1. Explain the difference between a chemical change and a physical change.
2. List examples of each.
Physical Change
A physical change occurs when the substance changes state but does not change its chemical composition. For example: water freezing into ice, cutting a piece of wood into smaller pieces, etc. The form or appearance has changed, but the properties of that substance are the same (i.e. it has the same melting point, boiling point, chemical composition, etc.)
Chemical Change
A chemical change occurs when a substance changes into something new. This occurs due to heating, chemical reaction, etc. You can tell a chemical change has occurred if the density, melting point or freezing point of the original substance changes. Many common signs of a chemical change can be seen (bubbles forming, mass changed, etc).

Kinetic Theory of Matter
Molecules are always moving. This is known as the kinetic theory of matter.
We measure this kinetic energy with a thermometer as temperature.
The greater the material's internal energy, the higher the temperature of that material.
Heat is the energy flow between objects of different temperature.
Heat and temperature are NOT the same.

2. Freezing
3. Sublimation
4. Deposition
5. Condensation
6. Vaporization
Phase Change Paragraph-Answers
At point A the substance exists in a solid state. With each passing minute, Energy/heat is added to the substance. This causes the molecules of the substance to move more rapidly which we detect by a temperature rise in the substance. At point B, the solid begins to melt. At point C, the substance is completely in a liquid state. The temperature at this point is called the melting point.
Between 9 and 13 minutes, the added energy increases the temperature of the substance. The substance changes from a liquid to a gas state. The temperature at this point is called the boiling point. By point E, the substance is completely in the gas phase. Beyond point E, the substance is still in the gas phase, but the molecules are moving rapidly as indicated by the increasing temperature.
Moving in the opposite direction on the graph, the temperature moving from point E to D is called the maximum condensation point and the temperature moving from point C to B is called the freezing point

Atoms and Elements
All matter is made of atoms. Atoms are tiny particles (PAR-tuh-kuhls). Even air is made of atoms. Atoms are small. A million billion of them fit in a teaspoon. No one can see them without help. It takes a strong microscope to see them.
When something is made of the same kind of atoms, it is called an element (ELL-em-ent). It is very hard to turn one element into another element. In other words, iron will always be iron. You can’t turn it into other elements. You can heat it. You can hit it. You can drop it in acid. It doesn’t matter what you do. It will still be iron. It may not look the same, but it will still be made of iron atoms.
There are about 100 types of atoms. They can be put together in many ways. Each way makes something different. This is called atomic arrangement (uh-TOM-ik uh-RANGE-muhnt).
Molecules and Compounds
Atoms can join to make molecules (MOL-uh-kyools). A molecule has two or more atoms stuck together. They become a new substance called a compound (KOM-pownd). A compound has different properties from the elements that make it.
For example, water is made from hydrogen and oxygen. But it isn’t like either of them. Water is a compound. Each water molecule has two kinds of atoms. There are two hydrogen and one oxygen atom. This is written as H2O. The number two means that there are two hydrogen atoms in the molecule. No number after the O means there is just one atom of oxygen.
Compounds are made by reactive (ree-AK-tiv) elements. Reactive elements join easily with others. Some elements are very reactive. Some are not. The more reactive an element, the more likely it will form compounds.

Warm Up- Warm Up:How Penicillin Was Discovered
In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria that had grown in this area had died. In the culture dishes without the mold, no clear areas were present.
Fleming hypothesized that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth. Fleming then added the nutrient broth in which the mold had grown to a culture of bacteria. He observed that the bacteria died which was later used to develop antibiotics used to treat a variety of diseases.

In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was beriberi. Symptoms of the disease included weakness and loss of appetite, victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria from the blood of patients with beriberi. The injected chickens became sick. However, so did a group of chickens that were not injected with bacteria.
One of the scientists, Dr. Eijkman, noticed something. Before the experiment, all the chickens had eaten whole-grain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman researched this interesting case and found that polished rice lacked thiamine, a vitamin necessary for good health.
