Grade 3 energy concepts quiz

📚 Quick Study Guide

• ⚡️ Energy is what makes things able to do work.
• ☀️ The sun is a major source of energy for Earth.
• 💡 Kinetic energy is the energy of motion (like a rolling ball).
• 🍎 Potential energy is stored energy (like a stretched rubber band or food).
• 🔥 Heat, light, and electricity are forms of energy.
• 🔄 Energy can change from one form to another. For example, a battery changes chemical energy into electrical energy.
• 🌱 Plants use sunlight to make food, which is stored energy.
