1. Science Starter Monday 9/12/16
Seats/groups are the same. I just rearranged the desks 
Pick up one of each pages from the front- bell work, notes, activity report, unit divider, and exit ticket.
Write in your agenda.
Answer the following on your science starter page
T./E.1-Engineers from an automobile company are making a new car. The seats in older models of cars become very hot. The engineers want seats in the new car to stay cool even in hot weather. What should be the first step toward solving this problem? How do you know?
While you wait on others to finish the bell work question, go ahead and be coloring the unit divider pink.

2. Essential Question
What is the relationship between potential and kinetic energy?

3. Stand up and make an “X” with your body. Don’t drop your arms
Stand up and make an “X” with your body. Don’t drop your arms. Try to stand as still as you can.
Holding this X position, you are gaining/storing potential energy. You’re just waiting for me to tell you to drop your arms.
This energy is waiting to be converted into kinetic energy.
Now, do a jumping jack. This is kinetic energy- energy of motion.

4. Energy is the ability to do work.
Work is the transfer of energy.
Work occurs when a force causes an object to move in the direction of the force.

5. You will be observing and recording the amount of work done by two marbles, of different sizes, as they roll down an inclined plane.
Your task will consist of placing each marble at the top of the incline to build potential energy; then, you will release that energy as each marble rolls down the incline. Take note of when the marbles reach their fastest speed.
Each marble should be positioned on the incline to strike the milk carton at the bottom. You will measure the distance the milk carton travels each time in centimeters. To be sure your results are accurate, you will roll each marble three times- starting with the smallest first. The second marble should be tested after all three trials of the smaller have been completed.
Now- On your activity page, form a hypothesis based on which marble you believe will or will not move the milk carton farther.

6. What is the relationship between work and energy
What is the relationship between work and energy? (Discuss with your neighbor.)
You can not have one with out the other.

7. Now, complete steps 2 and 3 of the marble roll with your group.
**Be sure to follow the steps on your activity report to also ensure no experimental errors are made. I will be walking around to guide you when needed.
You will have 8 minutes to complete steps 2-4.
REMEMBER to include if your hypothesis was correct or incorrect and explain why or why not. Conclusions should be about 3+ sentences.

8. Kinetic Energy is the energy of motion.
Potential Energy is the energy of shape or position (stored energy.)

12. Science Starter 9/13/16 Write in your agenda.
Write and answer the question below.
What is the relationship between potential and kinetic energy?

13. Science Starter 9/14/16 Write in agenda.
Answer the following on your bell work page for Wednesday.
--A company that manufactures machine parts began an engineering design plan, as shown. Write the steps in order using the answers below A
Test the final product. C
Conduct research on machine parts that already exist. B
Improve the design of the prototype. D
Start mass production of the machine part.

15. Mechanical energy is the total energy of motion and position of an object.
Mechanical energy = Kinetic energy + Potential energy

18. Elastic Potential energy - energy stored in stretched out items
Elastic Potential energy - energy stored in stretched out items. After the item is stretched it returns to its original position or shape.
Ex: bow strings, rubber bands

19. Gravitational Potential Energy - energy given to an object after it has been lifted or elevated Ex: book on a shelf

21. Chemical Energy Energy released from chemical reactions
Example: a battery
Chemical energy is a form of potential energy!!

22. Total energy of particles that make up an object; heat energy
Example: the sun
Also known as radiant energy

23. Energy of moving electrons
Example: hair dryer

24. Caused by the vibrations of electrically charged particles
Example: light bulb

25. Caused by an object’s vibration
Example: radio

26. The energy associated with changes in the nucleus of an atom
Example: nuclear power plant

27. Everything is made up of atoms!
They are made of protons, neutrons and electrons.

28. In order to create nuclear power an atom must either be split in two or joined with another atom.
This is not a process that is easily done. It requires a lot of work and highly qualified persons – as well as advanced technology.
