Introduce your child to the scientific concept of the relative weight of objects with this safe and simple art project. Children will have fun constructing the balance, and using it to weigh different materials.
What this activity will develop:
Science, art and thinking skills
What you'll need:
• Quart or half-gallon milk carton
• Cardboard strip, 1" x 12"
• 2 small styrofoam cups
• Beans, macaroni, shells, and other materials to weigh
What to do:
1. Cut off the top of the milk carton. Place sand inside to weight it down.
2. Punch a small hole in the exact center of one side of the milk carton near the top.
3. Punch a hole at the exact center of the cardboard strip. Then punch a hole at each end of the strip the same distance from the center.
4. Attach the cardboard strip to the carton with the brad.
5. Punch two holes through the top of each cup. Attach the cups to the strip of cardboard with string. Make sure the cups hang evenly.
Rules of Play:
1. Experiment to find two different objects that have the same weight according to the balance.
2. Put beans in one cup and dry macaroni in another. Keep adding, one at a time, until the cups balance.
