This Formative guides students through various energy transformation examples
Part 1: Use the embedded Phet simulation below to answer the following questions. Skip the Intro and click "Systems" to get started.
You will need to scroll back up to this Phet simulation when a question asks you to change something :)

Steps to Use the Simulator
1. In the simulator above, start by clicking on "Systems". If you accidentally clicked Intro, click "Systems" in the bottom black panel. If it doesn't launch, use your computer's refresh button.
2. Then check "Energy Symbols" on the right-hand side.
3. Click and drag the handle of the faucet to the right to start the water flow.
4. Watch carefully for a few moments.
5. Use the energy symbols to identify the energy transformations taking place.
Thermal >> Electrical >> Mechanical
Mechanical >> Chemical >> Light
Mechanical >> Chemical >> Thermal
Mechanical >> Electrical >> Thermal
Thermal energy can also be described as _________?
Electricity
Force
Heat
Light
The flowing water causes the wheel to spin. This is an example of mechanical energy. Mechanical energy is the combination of which two forms of energy? (click both)
Kinetic
Thermal
Chemical
Potential
Using the boxes at the bottom of the simulator, change the options to match the screenshot below:
1. Click Sun
2. Click Solar Panel
3. Click Fan/Wind Turbine
4. Don't forget to check "Energy Symbols" on the right-hand side again.
5. Watch carefully for a few moments.
What is the energy transformation taking place in this scenario?
Electrical >> Chemical >> Light
Mechanical >> Electrical >> Light
Light >> Electrical >> Mechanical
Light >> Chemical >> Mechanical
Use the sun/fan scenario above. What happened to the system when you adjust the setting to lots of clouds? (Check the 2 correct answers)
More light energy is reaching the solar panel to generate electricity
Less light energy is reaching the solar panel to generate electricity
The fan spins faster
The fan slows down and eventually stops
Using the boxes at the bottom of the simulator, change the options to match the screenshot below.
1. Click bicycle
2. Click wheel
3. Click lightbulb
4. Don't forget to check "Energy Symbols" on the right-hand side again.
5. Use the blue slider to make the kid pedal.
6. Watch carefully for a few moments.
What is the energy transformation taking place in this scenario?
Chemical >> Thermal >> Electrical >> Light
Mechanical >> Electrical >> Thermal >> Light
Mechanical >> Light >> Chemical >> Thermal
Chemical >> Mechanical >> Electrical >> Light
Using the bicycle/lightbulb scenario from the previous question, watch what happens after the child has been pedaling for a while.
Where is this chemical energy coming from and why did he stop?
Food; He needs to eat to gain more energy
Rest; He needs to sleep to gain more energy
Sun; He needs to lay in the sun to recharge
Batteries; He needs to replace his batteries to gain more energy
Wasted energy is the energy that is being released into the environment instead of being transferred to another object.
What type of energy is being "wasted" by the bicycle in the scenario below?
Chemical
Mechanical
Thermal
Electrical
Using the bicycle scenario, switch out the type of lightbulbs. Observe and Compare the energy being given off by the two different light bulbs. What is different about them?
The coiled one produces more thermal energy
The rounded one produced more thermal energy
The coiled uses chemical energy
The rounded one uses chemical energy
