My child built a catapult

Science

• The child learned about potential and kinetic energy by understanding how the catapult stores and releases energy.
• They learned about force and motion by observing how the catapult launches objects through the transfer of energy.
• The child learned about engineering and design by building and modifying the catapult to improve its performance.
• They learned about angles and trajectory by experimenting with different launch angles to achieve different distances.

For continued development, encourage the child to explore other simple machines and their applications, such as levers, pulleys, and inclined planes. They can also apply the concepts learned from the catapult to understand how real-life machines and devices work.
