In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this activity, learners discover how NASA engineers develop experimental aircraft.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity (page 10 of the PDF) learners will explore the historical progression of siege weapons to gain an understanding of how the addition and modification of parts can change the efficiency

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!
