Grade 4 students trace real-world energy transfers across familiar devices and activities. This worksheet covers bicycles transforming chemical food energy into kinetic motion, microwaves changing electrical energy into heat, guitar strings making sound waves, flashlights producing light, dams generating electricity, and solar panels capturing sunlight. Through fill-in-the-blank items and a four-pair matching activity, learners practice identifying the input and output energy forms. Aligned to NGSS 4-PS3.
Style:
Energy: Forms and Transfer
Part A: Fill in the Blank
Write the missing word or number on each line.
1. When you ride a bike, the chemical energy from food in your body changes into kinetic energy of motion.
2. A microwave oven changes electrical energy into heat energy that warms your food.
3. When you pluck a guitar string, motion energy transforms into sound waves you can hear.
4. A flashlight changes the chemical energy in its battery into electrical energy and then into light energy.
5. When water flows through a dam, its kinetic energy can spin a turbine and make electrical energy.
6. A toaster turns electrical energy into heat energy and a small amount of light energy when the wires glow red.
7. A solar panel transforms light energy from the sun into electrical energy.
8. When you rub your hands together quickly, kinetic energy turns into heat energy that warms your skin.
9. A speaker takes electrical energy and changes it into sound energy that travels through the air.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
