Build a popsicle stick catapult

Develop an understanding of levers and build a popsicle stick catapult from craft sticks with this free STEM lesson plan.

This is an exciting and engaging way to learn about physics and engineering. With the right materials, build a simple yet effective catapult capable of launching chocolate eggs up into the air!

This lesson plan is perfect for KS3 students and can be used as a fun one-off main activity to introduce levers.

This is one of a set of resources designed to allow learners to use Easter themes to develop their knowledge and skills in Design & Technology, Mathematics and Science. This resource involves making a simple catapult which works as a lever to propel a chocolate or mini egg.

This activity will take approximately 50 – 70 minutes to complete.

Also included is a fun crossword using words from the activity to promote sticking learning.

Tools/resources required

Craft sticks (at least 7 per learner)
Small elastic bands (at least 7 per learner, plus spares)
A teaspoon (metal or plastic)
Chocolate mini eggs (or similar)

For the extension activity:
Pencils (or similar, such as dowel rods)
Elastic bands

The engineering context

Levers are one of the simplest machines and are used in many applications. These include pliers, scissors, brake pedals and wheels and axles. The principles of levers are also used in many applications when designing sports equipment, such as cricket bats, golf clubs and hockey sticks.

Suggested learning outcomes

After completing this Easter themed engineering resource students will be able to describe the three classes of lever and they will be able to make a structure.
