How Energy Changes from One Form to Another 

Introduction

Energy is all around us. It lights up our homes, powers moving vehicles, and helps fans spin. Whenever energy changes from one form to another, it is called energy transformation.

In this energy transformation science project, you will discover how the air from your breath can make a simple vehicle move. This fun STEM activity shows that science is happening all around us and helps students understand important concepts through hands-on learning.

By completing this energy transformation science project, children can explore how energy is converted into motion in an exciting and easy-to-understand way.

STEM Activity

Materials Required

1) Cardboard

2) Chart- 1

3) Cellotape- 1

4) Skewers/broomsticks – 2

5) Scissors

6) Straws – 3

Draw a circle of radius 2 cm on a thick cardboard as shown and cut it. Cut 4 circles of the same size (medium) as shown.

Step-by-Step Procedure for the activity

Step 1: Cut the cardboard into a rectangle that’s 10 centimeters by 15 centimeters.

Step 2 :Now place the straws on both sides of the cardboard. Cut the parts of the straws and secure them using cellotape.

Step 3 : Next insert the skewers or broomsticks through the straws on the cardboard.

Step 4 :Make a hole at the center of each wheel which’s a circle.

Step 5 : Attach the wheels to the skewers on the vehicle base. Now your vehicle base is ready to go. It is a car.

Step 6 : Cut the chart paper into a rectangle that’s the same size as the cardboard 10 centimeters by 15 centimeters.

Step 7: Fold the chart paper in half to make two halves. Draw a line at the center of the chart paper. On the side of the chart paper fold about 1 centimeter and mark it. Then cut a slit where the lines intersect on the chart paper.

Step 8 : Stick the chart paper at the center of the cardboard on the vehicle base.

Step 9 : Blow air through the straw towards the chart paper, on the vehicle base. Watch the vehicle base move and watch the car move.

Observation: What Do You Notice?

• The vehicle moves forward when you blow through the straw.
• The chart paper works like a sail and catches the moving air.
• Blowing harder makes the vehicle travel faster.
• The wheels rotate smoothly on the skewers.
• The vehicle stops when you stop blowing because the pushing force is no longer present.

These observations make this energy transformation science project easy to understand and enjoyable for students of all ages.

Scientific Explanation

When you blow air through the straw, the moving air pushes against the chart paper. This push creates a force that moves the vehicle forward. The wheels reduce friction with the ground, allowing the vehicle to roll smoothly.

In this energy transformation science project, the energy from your breath changes into the kinetic energy of the moving vehicle. This process is called energy transformation because one form of energy is converted into another. Activities like this energy transformation science project help students understand scientific concepts through practical experiments instead of only reading about them.

FAQ

1. Why does the vehicle move?

The vehicle moves because the air we blow pushes the chart paper forward 

2. What type of energy is used in this activity?

The activity uses energy from our breath, which changes into movement energy

3. Why are straws used?

Straws help hold the skewers and allow the wheels to rotate smoothly.

4. What happens if we blow harder?

The vehicle moves faster because more force is applied 

5. What do students learn from this activity?

Students learn about energy transformation, force, motion, and simple engineering concepts

6. Can I use different materials to build the vehicle?

Yes. You can use lightweight cardboard, foam sheets, or recycled materials for the base. Just make sure the wheels can rotate smoothly for the best results.

7. What kind of energy transformation happens in this science project?

In this STEM activity, the energy from your breath (air energy) is transformed into the kinetic (movement) energy of the vehicle, causing it to move forward.

8. Why do the wheels need to spin freely?

The wheels need to spin freely because they reduce friction with the ground. Less friction allows the vehicle to move more smoothly and travel farther.

9. How can I make the vehicle travel farther?

You can make the vehicle travel farther by using lightweight materials, ensuring the wheels rotate easily, and blowing a steady stream of air through the straw.

10. What science concepts do students learn from this STEM activity?

Students learn about energy transformation, force, motion, air pressure, friction, and simple engineering design while building and testing their own air-powered vehicle.
