Science
- The child learned about the concepts of force and motion by building a catapult.
- They explored the principles of energy transfer as they observed how the stored energy in the catapult's elastic bands was converted into kinetic energy when launched.
- They gained an understanding of trajectory and angles as they aimed the catapult at the target.
- They learned about measurement and estimation as they made predictions and measured the distance the projectile traveled.
For continued development, encourage the child to experiment with different variables, such as adjusting the tension of the catapult, using different projectiles, or changing the angle of launch. They can also investigate the effect of gravity and test different materials to build the catapult for a deeper understanding of engineering principles.
