Built a lever catapault

Math

• The child learned about measurement and estimation by determining the distance the projectile traveled.
• They applied basic addition and subtraction skills to calculate the force needed to launch the projectile.
• The child explored the concept of angles by adjusting the angle of the lever to achieve different launch heights.
• They practiced counting and tallying by keeping track of the number of successful launches versus unsuccessful ones.

Science

• The child gained an understanding of simple machines, specifically levers, as they built and used the catapult.
• They learned about potential and kinetic energy as they observed the transfer of energy from the pulled lever to the launched projectile.
• They explored the concept of force and motion by experimenting with different amounts of force to launch the projectile varying distances.
• The child practiced the scientific method by making observations, conducting experiments, and drawing conclusions based on their findings.

Continued Development Tip: Encourage the child to experiment and make modifications to their catapult design. They can try using different materials, adjusting the length of the lever, or changing the angle of the launch. This will help them understand the impact of these variables on the catapult's performance and further develop their problem-solving and critical thinking skills.
