Why? How do the different projectile designs impact the force? What can you knock over? Can they come up with a way to measure the height reached as well as length?ħ-9 year olds might be interested in coming up with their own catapult designs. You can talk about how using the same size projectile each time, and firing the catapults from the same point (or starting line), creates a “fair test”.ĥ-6 year olds might be interested in taking measurements themselves and recording results in a table or graph. You could dot with chalk where each projectile reached so you talk about longest and shortest distances afterwards. With a little practice, preschoolers should be able to launch projectiles and compare distances. My daughters were 4 & 6.5 years old when we did this. This is a fun activity that can span multiple age groups, from preschoolers, to kindergarteners, to primary (elementary) school aged kids. But this time, I thought we’d try making classic craft stick catapults – mostly because I’ve been wanting to make some for ages and ages and ages. We’ve made easy upcycled catapults before (which were so much fun!). (We also submitted a Why STEM for Girls is So Important post to that series too – because that’s something that we tend to be a bit passionate about around here!) So I’m pleased to present this as the C is for Catapult submission in this year’s A-Z of STEM Activities for Kids series that Little Bins for Little Hands is running. Making catapults involves three of the four pillar STEM subjects – there’s the whole projectile, forces, physics thing ( Science = tick!), creating a machine and evaluating different designs ( Engineering = tick!) and measuring the height and distance of your projectiles ( Maths = tick!). Y’all know what a STEM activity is, right? STEM stands for Science, Technology, Engineering and Math, and a great STEM activity is one that incorporates two or more of these pillar subjects, in an open-ended, lets-find-out, hands-on kinda way. Making catapults is one of those classic STEM activities that are so much fun. How to make (and test) DIY craft stick catapults! Fun catapult STEM project for kids, that combines physics, engineering and math with play.
