Technology and Energy Worksheets for Child Development ... - Free Printable

Absolutely! Let’s go through each image one by one and identify the form of energy it represents. This is a great exercise to understand how energy appears in everyday life and science.

🔹 Row 1:

1. Lamp (desk lamp with light on)
→ Light Energy (also called Radiant Energy)
*Explanation:* The lamp emits visible light, which is a form of electromagnetic radiation. Light energy travels in waves and allows us to see.

2. Batteries
→ Chemical Energy
*Explanation:* Batteries store energy in chemical form. When connected in a circuit, chemical reactions occur that release electrical energy.

3. Sun
→ Radiant (or Solar) Energy
*Explanation:* The sun emits energy across the electromagnetic spectrum — mostly visible light, infrared, and ultraviolet. This is often called solar or radiant energy.

🔹 Row 2:

4. Donut (food)
→ Chemical Energy
*Explanation:* Food contains stored chemical energy in its molecules (like carbohydrates and fats). Our bodies break these down to release energy for movement and function.

5. Waterfall / Dammed water falling
→ Mechanical Energy (specifically Gravitational Potential → Kinetic Energy)
*Explanation:* The water at height has gravitational potential energy. As it falls, that converts into kinetic energy (energy of motion).

6. Atom model (nucleus + orbiting electrons)
→ Nuclear Energy
*Explanation:* This symbolizes the energy stored in the nucleus of atoms. Nuclear energy is released during fission (splitting atoms) or fusion (joining atoms), as in the sun or nuclear power plants.

🔹 Row 3:

7. Person riding a bicycle
→ Kinetic Energy (and also Mechanical Energy)
*Explanation:* The moving cyclist and bike have kinetic energy — energy due to motion. Muscles convert chemical energy into mechanical work to move.

8. Trumpet with musical notes
→ Sound Energy
*Explanation:* When the trumpet is played, vibrations travel through the air as sound waves. That’s sound energy — mechanical wave energy we can hear.

9. Campfire / Burning wood
→ Thermal Energy (Heat) and Light Energy
*Explanation:* Fire releases heat (thermal energy) and light (radiant energy) through combustion — a chemical reaction between fuel and oxygen.

## ✔ Final Answers (Fill-in-the-blank):

Row 1:
1. Light Energy
2. Chemical Energy
3. Radiant (or Solar) Energy

Row 2:
4. Chemical Energy
5. Mechanical Energy (or Kinetic/Potential Energy)
6. Nuclear Energy

Row 3:
7. Kinetic Energy (or Mechanical Energy)
8. Sound Energy
9. Thermal Energy (and/or Light Energy)
