Al thinks different size balloons create different forces as they let out air. How can he plan an experiment to test this variable?
Propel different size toy cars over the same surface with the air from different size balloons.
Let the air out of different size balloons to see which empties faster.
Propel the same toy car over the same surface with the air from different size balloons.
Propel the same toy car over the same surface with the air from different size balloons.
