Build a Catapult STEM Challenge for Middle School Science NGSS MS-ETS1-1, 1-2, 1-3, 1-4

Your middle school science class is sure to LOVE using the design process to build a catapult!

Students will design and build a catapult. Students will learn about mangonels and trebuchets. Using the design process, students will build a catapult, test it, evaluate it according to the criteria and constraints, compare it with other design solutions, and improve their own design solutions.

They will also learn about the mangonel which uses tension to power the launch and the trebuchet which uses a counterweight and gravity to launch the projectile. Your class will love this engaging STEM activity and they will love learning about these two mechanisms for launching a projectile.

This unit contains a variety of different activities to keep your students engaged!

It includes a slideshow on trebuchets and mangonels with an interactive note taking guide, information on planning an investigation, information on criteria and constraints, and follow-up pages.

My students used this resource to help them compete in a school wide STEM competition. My class made catapults and were so proud to launch them for the school. Great information and clear directions.
