Built a catapult

Science

• The child learned about force and motion by understanding how the catapult works using elastic potential energy.
• They explored the concept of angles by adjusting the angle of the catapult arm to achieve different flight paths.
• They learned about potential and kinetic energy as they observed the transformation of energy when launching objects.
• They gained an understanding of gravity as they observed how it influenced the trajectory of the launched objects.

For continued development, encourage the child to experiment with different materials to build the catapult, such as popsicle sticks or rubber bands. They can also explore the concept of trajectory by adjusting the force applied to the catapult arm and experimenting with different launch angles. Additionally, they can research the history of catapults and learn about their various uses throughout different time periods and cultures.
