ANET
Today we will be taking the ANET Assessment. Reasons why the ANET assessment is important:
- It will be used to predict parcc performance and intervention grouping
- You will recieve additional math help based on your ANET/IReady Score

Warm Up Question
When does an object have more thermal energy? When it is hot or cold? Explain using an example.
Warm Up Question
Remember: Thermal energy is the internal energy of an object due to the movement of it's molecules.

Investigation
Investigation
1. How does the speed of a moving object affect the amount of kinetic energy it has?
2. How does the mass of a moving object affect the amount of kinetic energy it has?
Experimental Procedure
1. Measure the thickness of a clay ball by sticking a toothpick in its center. Mark the toothpick at the top of the clay, remove the toothpick and measure the length of the portion that was in the clay. Make the ball as close as possible to 3cm in diameter.
2. Drop a large can on the clay ball from a height of about 30cm. Carefully remove the can, trying not to change the shape of the modeling clay.
3. With the toothpick, measure the thickness of the center of the clay ball. Subtract it from the original thickness to find how much it was compacted.
Data Analysis
1. For the first table, Describe how the thickness (dependent variable) changed when you changed the Speed of the Can (independent variable).
2. For the second table, Describe how the thickness (dependent variable) changed when you changed the Can Mass (independent variable).
Conclusion
1) How does speed affect the amount of kinetic energy in a moving object? Explain how you know by stating your claim, the evidence for your claim, and your reason why this evidence supports your claim.
2) How does mass affect the amount of kinetic energy in a moving object? Explain how you know by stating your claim, the evidence for your claim, and your reason why this evidence supports your claim.
Exploring the Rolling Can
Exploring the Rolling Can
Take out a sheet of paper and label it with your name and class.
1. Describe what happened when the can was rolled
Exploring the Rolling Can
2) When the can stops rolling, does it have KE or GE?
3) When it starts rolling again, does it have KE or GE?
4) Where did this energy come from?
5) Can we describe how the rolling can works using KE and GE?
Exploring the Rolling Can
6) What types of energy does the rubber band have when it is moving toward the
ceiling? (KE and GE)
7) What happens to each of these energy types as the rubber band moves? (KE ➞, GE ➞)
8) Did the rubber band have kinetic energy and gravitational energy before I released it?
9) How do you know?
Exploring the Rolling Can
How does the can, washers and rubberband make the rolling can work?
Conclusion- Why does the Ball Stop
If nobody catches a ball, it hits the ground, bounces a couple of times, and then stops. What
happens to its energy? Where does it all go? The following paragraph gives you a hint.
You learned that energy may also be transferred to an object’s surroundings. For example, a
swinging pendulum gradually transfers all its kinetic energy to the surrounding air molecules.
The pendulum slows down until it finally stops, losing energy all the time, while the air
molecules gain kinetic energy and move faster than they did before.
13. Why does the ball stop?
