Built catapult

Science

• The child has learned about motion and force as they understand how the catapult launches objects by creating tension in the rubber band and releasing it.
• They have also learned about potential and kinetic energy as they observe the stored energy in the rubber band being converted into motion when the catapult is released.
• Additionally, the child has learned about angles and trajectory as they experiment with different launch angles to see how it affects the distance and height the object travels.
• They have also gained knowledge about simple machines, specifically levers, as they understand how the arm of the catapult acts as a lever to increase the force applied to the object being launched.

To further develop their understanding, the child can experiment with different materials and designs for their catapult. They can explore how the length and tension of the rubber band affect the launch distance, or how the size and weight of the projectile impact its trajectory. They can also learn about historical catapults and how they were used in warfare, exploring different designs and techniques used throughout history.
