Hands-on Activities
Use items you have at home: balloons, balls, a fan and a stopwatch to act out or understand the forces that act on an airplane. Four forces affect an airplane while it is flying: weight, thrust, drag and lift. See how they work when you do these activities as demonstrations.
These activities are adapted from the “Four Forces (K-4)” and “Four Forces (5-8)” educator guides.
