Hands-on activities like this engage children actively, making complex concepts easier to grasp. By seeing the real-time effects of their actions, students can better relate to scientific principles.
1. Cut a piece of string about 1 meter long and tie it to two chairs. 2. Thread the straw onto the string so it can slide freely. 3. Inflate the balloon but don't tie it; pinch the end to keep the air in. 4. Tape the balloon to the straw without blocking the straw's opening. 5. Release the balloon and watch it fly along the string. 6. What did you notice about the balloon's movement?
