The Button Balance Scale
Steps:
- Lay a pencil flat on a table. Use a small piece of masking tape to stop it from rolling.
- Place the middle of the ruler on top of the pencil. It should tilt back and forth like a seesaw.
- Use your thumb and pointer finger to pick up a single button from your collection.
- Place the button gently on one end of the ruler.
- Now, try to place a second button on the other side to balance the weight.
- When the ruler stays level without touching the table, your child has mastered the challenge of finding the center of gravity.
- Keep adding buttons to see how many the scale can hold before it tips.
Safety Tip:
Adult supervision is required. Buttons are a choking hazard. Keep them away from small children and pets at all times.
