- ⚡ I will learn that energy is all around us.
- 💫 I will find out that we need energy for every movement or action.
- 🔮 I will make predictions about what might happen in an investigation.
- 🎯 I will show and explain how energy makes things move.
- 🧠 I will check if my results support or do not support my prediction.
Let’s explore how energy makes our world move! ⚡🌍
🌟 Key Words
- energy
- predict
📖 Tap to Learn the Meanings!
- ⚡ energy: the power to make things move or work — like heat, light, or movement.
- 🔮 predict: to say what you think will happen in the future based on clues or facts.
Great job learning new words! 🎉
Energy is all around us
Energy is everywhere around us.
Living things have energy. We get our energy from the food we eat. We use this energy to move, grow, breathe and carry out all our other life processes.
Non-living things also have energy. For example, there is energy in moving air that makes a wind turbine turn. There is also energy in light, heat and sound.
Light, heat and sound are forms of energy. Movement is also a form of energy.
Quick Fact
Energy cannot be created or destroyed — it can only change from one form to another, such as from light to heat or from movement to sound.
⚡ FUN QUESTIONS — Energy in Pictures
1. Look at the pictures. Where is the energy in each picture? 🔍
🌟 Show answer
- Flag — energy in the moving wind 🌬️
- Kettle — energy in the heat 🔥
- Plant — energy from the sunlight 🌞
- Drum — energy from sound vibrations 🥁
- Bird — energy in the moving muscles 🕊️
2. What type of energy does each picture show? 💡
🌟 Show answer
- 1️⃣ Wind energy 🌬️
- 2️⃣ Heat energy 🔥
- 3️⃣ Light energy 🌞
- 4️⃣ Sound energy 🥁
- 5️⃣ Movement (kinetic) energy 🕊️
What is energy?
We know that everything has energy. We can’t always see energy, but we can observe the things that energy does.
Energy makes things move. All moving things have energy.
Energy also makes things change. For example, a moving ball can break a window.
We can think of energy as anything that can cause movement or carry out an action. We need energy for everything we do.
Quick Fact
Energy is measured in joules (J). Even small actions like blinking your eyes use a tiny amount of energy.
🔬 Think like a Scientist: Demonstrate What Energy Does
🤔 Question: How can we show that energy makes things move?
🧰 You will need: A ping pong ball or a piece of paper crumpled into a ball 🏐
📝 Method:
- Flick the ping pong ball with your finger. What happens?
- Why do you think this happens? Use the word energy in your answer.
- Predict what will happen if you flick the ball harder. Remember, a prediction is what we think will happen based on our knowledge and experience.
- Flick the ball again. Was your prediction correct?
- Say why you think this happened.
💡 Flicking the ball transfers energy and makes it move!
❓ Questions:
🪞 How am I doing?
| How well can I: | Very well 😄 | Quite well 🙂 | I need help 😕 |

| Name three examples of energy around us | |||
| Describe how I use energy to make a ball move |
🌟 Tap to See Answers
- 1: The ball and your finger had energy. You used energy from your muscles to move the ball.
- 2a: Energy changed from your moving hand to the ball.
- 2b: When you added more energy (flicked harder), the ball moved faster and further. 💨
- 3: You could blow on the ball to show that moving air transfers energy too. 🌬️
Excellent work exploring how energy makes things move! ⚡👏
