Catapults

60-90 Minutes | 1st – 8th Graders

catapultsThe catapults activity introduces the engineering design process whilst also giving a basic introduction to trajectory physics. Students learn about different types of catapults and their historical and modern uses. Students then design and build their own catapults using popsicle sticks, tape, rubber bands, and spoons. Launching at targets allows the students to learn the difference between accuracy and precision. Afterwards, the class reviews the results to see which catapult design worked the best!
