In this session, we will learn how to make a pencil catapult, to learn about Newton’s Laws of Motion! This activity focuses on Newton's Second Law of motion, and demonstrates it through the launching of the catapult. The recommended age group for this project is 5 to 10 years old, although all ages are welcome!
MATERIALS NEEDED:
- 2 pencils
- 2 to 4 rubber bands - An eraser - A bottle cap - Something to launch (a button, small rubber ball, paper clip) How To
Step 1: Take 2 pencils and put an eraser in between them, about an inch from the end of the pencil.
Step 2: Wrap a rubber band around the 2 pencils, right in front of the eraser. Step 3: Take another rubber band and wrap it around the middle of the 2 pencils. *In Steps 2-3, you can use as many rubber bands as you need to make it tight and secure!* Step 4: Take your bottle cap, and tape it onto the top pencil (the end without the eraser). Make sure you leave space at the end of the pencil where you can push down. Step 5: Place the object that you will be launching into your bottle cap. Step 6: Push down and launch! the lesson
Throughout this class, we will be explaining Newton’s Laws of Motion. The kids would learn about Newton’s three laws detailing force, inertia, acceleration, action and reaction, and more. They will see how these topics affect their catapult, for example, how the amount of force they apply when launching changes the how far the object accelerates. This practical application of the topics learned ensures that they would remember all the content, and push them to make more scientific connections in real world situations. You can find our explanations in the presentation below.
