Kids learn best when they are involved in their learning. This can mean asking questions, having discussions and exploring new concepts. The second grade is using LEGOS to explore simple machines. What better way to learn about forces and motions than by building a catapult with Legos and then testing it out!
Students in second grade are studying the scientific method by creating a hypothesis, deciding on similar procedures and then collecting data to determine the most effective design of a catapult. The students began the process by using Legos to create a catapult that would launch cotton balls and ping pong balls. They worked in teams of four to provide an opportunity for team work.
Once the catapults were finished they took turns launching the different materials to determine which one would go further. They used measuring tools to calculate the distance of the objects that they launched using both inches and meters. As they launched each object they collected data and began to compare their findings. Why did one cotton ball fly further than another one? Does force have anything to do with that? The students began the early discussion that all scientists have when they begin to analyze their data!
Science activities help children to enhance their critical thinking skills. Students ask how, when and why questions as they discover new ways to analyze and explore.
