Grade 4 Science learners apply energy ideas to everyday devices in this worksheet, including toasters, lamps, flashlights, phones, hairdryers, and blenders. Sentence corrections fix common misconceptions, fill-in-the-blank questions reinforce key forms such as heat, sound, and chemical energy, and short-answer prompts ask students to trace energy through real machines. Hints and explanations support each item so Grade 4 students can connect classroom vocabulary to the world around them.

Energy: Forms and Transfer
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A toaster only changes electrical energy into light energy.
Rewrite: A toaster changes electrical energy mostly into heat energy.
2. Fix the sentence:
A flashlight uses sound energy to light up the room.
Rewrite: A flashlight uses electrical energy from batteries to make light energy.
3. Fix the sentence:
A cell phone only uses electrical energy and gives off no other form.
Rewrite: A cell phone uses electrical energy and gives off light, sound, and a little heat.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A lamp turns electrical energy into light and heat energy.
2. A toy car with a wound-up spring has stored potential energy.
3. A speaker turns electrical energy into sound energy.
4. A battery in a flashlight stores chemical energy until you turn it on.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. How does a hairdryer change one form of energy into two other forms?
A hairdryer plugs into the wall and uses electrical energy. Inside, the electricity makes a small motor spin, which is motion energy, and it also heats up a coil of wire, which gives off heat energy that warms the air blowing on your hair.
2. Pick a kitchen device and describe the energy changes that happen when it is turned on.
A blender uses electrical energy from the wall outlet. The electrical energy goes into a motor that turns the blades very fast, which is motion energy. The spinning blades also make sound energy and a little heat as they cut through the food inside.
