Grade 4 Energy Changes worksheet
from Gradelings · Name: ______________________
How to explain it
- Energy can change from one form to another.
- Batteries and food store chemical energy. Wires carry electrical energy.
- Bulbs give off light, toasters give off heat and speakers give off sound.
- To follow energy, start where it is stored and track each change.
Example: Which energy change happens in an electric fan? A fan plugs into the wall, so it uses electrical energy. Its blades spin, which is motion. Answer: electrical → motion
Question 1
Follow the energy in a flashlight. Put the steps in order.
- 🔋The battery stores chemical energy
- 💡The bulb gives off light
- ⚡Electricity flows through the wires
The battery stores chemical energy → Electricity flows through the wires → The bulb gives off light
Hint: The battery stores chemical energy. It becomes electrical energy in the wires, then light in the bulb.
Question 2
Geothermal energy uses…
🌋- heat from deep inside Earth
- light from the moon
- energy from the wind
- heat from burning coal
heat from deep inside Earth
Hint: Geo means Earth and thermal means heat. Hot springs are a clue that Earth is hot inside!
Question 3
Renewable or non-renewable? Tap an item, then tap its basket.
Sort into: ♻️ renewable · ⛽ non-renewable
- ☀️sunlight
- 🔥natural gas
- 🌬️wind
- 🌋heat from inside Earth
- 🪨coal
- 🛢️oil
♻️ renewable: sunlight, wind, heat from inside Earth · ⛽ non-renewable: natural gas, coal, oil
Hint: Renewable resources are replaced by nature quickly. Non-renewable ones took millions of years to form and can run out.
Question 4
What is one way to save energy at home?
- 💡Turn off lights when you leave a room
- 🧊Keep the fridge door open
- 📺Leave the TV on all night
- 🪟Open the windows with the heat on
💡 Turn off lights when you leave a room
Hint: Using less electricity and heat saves energy and money.
Question 5
Which energy change happens when you rub your hands together fast?
👐rubbing hands- chemical → electrical → light
- motion → heat
- electrical → light
- chemical → heat and light
motion → heat
Hint: Ask yourself: what kind of energy goes in, and what kind comes out? Here it's motion → heat.
Question 6
Which statement about energy is true?
⚡- It can be made from nothing
- It disappears after we use it
- It can only be in the form of light
- It can change form, but it is never destroyed
It can change form, but it is never destroyed
Hint: Energy just changes from one form to another, like electrical energy changing into light and heat.
Question 7
Energy from the sun reaches Earth as…
☀️- light and heat
- chemical energy in batteries
- sound and motion
- electricity in wires
light and heat
Hint: Sunlight lights up the day and warms the land, water and air.
Question 8
Which energy change happens in a light bulb?
💡light bulb- electrical → light
- electrical → sound
- light → electrical
- chemical → electrical → light
electrical → light
Hint: Ask yourself: what kind of energy goes in, and what kind comes out? Here it's electrical → light.
Question 9
Why are coal, oil and natural gas called non-renewable?
🛢️- They come from the wind
- They will never run out
- They took millions of years to form, so they can run out
- They can be made again in a day
They took millions of years to form, so they can run out
Hint: These fuels formed from ancient plants and animals over millions of years. We use them much faster than that.
Question 10
Which energy change happens when you hit a drum?
🥁drum- motion → sound
- electrical → sound
- sound → electrical
- chemical → motion
motion → sound
Hint: Ask yourself: what kind of energy goes in, and what kind comes out? Here it's motion → sound.
Answer key
- 1. The battery stores chemical energy → Electricity flows through the wires → The bulb gives off light
- 2. heat from deep inside Earth
- 3. ♻️ renewable: sunlight, wind, heat from inside Earth · ⛽ non-renewable: natural gas, coal, oil
- 4. 💡 Turn off lights when you leave a room
- 5. motion → heat
- 6. It can change form, but it is never destroyed
- 7. light and heat
- 8. electrical → light
- 9. They took millions of years to form, so they can run out
- 10. motion → sound
