14. Energy Source Questions
What is energy?
Energy makes things happen.
All actions are the result of energy.
Energy is the ability to do things.

15. Energy Source Questions
What are some of the different kinds on energy?
Electricity
Heat
Sound
Light
Motion
Chemical energy

16. Energy Source Questions
3) What are some of the sources of stored energy that people use?
Batteries
Fuel
Foods
How are food, fuel, and batteries alike?
They have energy stored as chemical energy.

17. Energy Source Questions
5) What is the source of most of the energy used by people? Explain.
The Sun.
Plants capture the Sun’s energy as chemical energy. That energy is in food and fossil fuels (gas). Food and fuel are the energy sources that people use most often.

21. Energy Conversion
See that truck driving by? It is powered by sunlight. Brad’s friend said, No it isn’t, it’s powered by gasoline. Explain why Brad said the truck was powered by sunlight.

22. Energy Conversion
Energy from the Sun is absorbed by plants and converted into chemical energy (food). The chemical energy changed into oil, a fossil fuel, which is made into gasoline. The gasoline is burned, releasing heat. Heat drives the car forward. The original source of energy was the Sun, so the car is driving on solar energy that has been converted into other forms by plants and burning. Using Energy Video

23. Using Energy Questions
What is stored or potential energy?
Energy that is available to make things happen.
What is kinetic energy?
The energy of motion. All moving things have kinetic energy.

24. Using Energy Questions
Name at least three types of energy that come from the Sun?
Heat
Light
Electricity
Chemical

25. Using Energy Questions
4) What is the source of most of the energy used by people? Explain how it works. Plants use solar energy (sun) to grow. Plants grow and store energy. Humans and animals eat plants and change the stored energy in the plants into energy to help them move and grow.

26. Energy Transfer Vocabulary
What I learned today
Sketch
The movement of energy from one thing to another or the change of energy form one form to another
Energy is moved (transferred) from one place to another by: wires, moving objects or waves
Energy transfer
Repeating movement like up and down (transverse wave) or back and forth (compression wave)
wave

27. Water Waves What action did you observe? Waves in the water

32. Energy Transfer Questions
Where do people get energy?
From food
Why does a car need gasoline to run?
Gasoline is fuel that is burned to make the power to move the car.

33. Energy Transfer Questions
What kinds of things have moving energy?

-Rolling a bowling ball down an alley
-Rolling downhill on a skateboard
-Burning gasoline to power a car
-Burning wood to make steam to drive a train
What is fuel used for?
Fuel is stored energy that is burned to make things happen.

35. Energy Transfer Questions
How does energy from the Sun get converted into energy that can be used by humans and other animals?
Plants use solar energy (sun) to grow. They store energy. We eat the plants, the stored energy is changed into energy to help us move and grow.

36. Energy Transfer Summary
Energy is carried from one place to another by waves, electric current or moving objects.
Sound Waves--Objects push on air creating waves. Waves move through the air until they hit your ear. The energy in the sound wave moves the bones in your ear, and you hear sound.
