built a lego catapult

Math

• The child learned about measurement and estimation by determining the distance the lego catapult could launch objects.
• They practiced counting and addition by keeping track of how many objects were launched and how many were successful hits.
• They explored geometric shapes and angles by observing the trajectory of the launched objects.
• The child learned about force and motion by experimenting with different amounts of tension in the catapult's rubber bands.

Science

• The child learned about potential and kinetic energy by observing how the rubber bands stored energy and transferred it to the launched objects.
• They explored the concept of leverage and simple machines by understanding how the lever arm of the catapult increased the force applied to the object.
• The child practiced the scientific method by hypothesizing and testing various modifications to the catapult design.
• They learned about projectile motion and trajectory by observing how the launched objects followed a curved path.

Continued development: Encourage the child to further explore the concepts of force and motion by experimenting with different catapult designs and materials. They could also investigate the relationship between the angle of the catapult arm and the distance the object travels. Additionally, they could explore the concept of energy conservation by comparing the distance the object travels with different amounts of potential energy stored in the rubber bands.
