Catapults

Engineering enthusiasts are sure to explode in understanding as they practice the engineering design process (EDP). A container of "toxic popcorn" is placed in the classroom. Teams must work together to devise a method for removing it...

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach the proper...

Just this once, it's okay to throw things in class. Out of craft sticks and rubber bands, pupils build catapults to launch an object of choice. This can be a ping-pong ball, a marshmallow, or any other small item. As long as it hits the...

Watch your marshmallows fly. The engaging STEM activity has groups create a catapult to launch marshmallows. After testing their prototypes, they consider improvements and redesign their catapults.

Solar energy is an amazing alternative ... but, not always particularly portable! Challenge young scientists to a folding solar panel build-off with an easy-to-execute activity. Scholars brainstorm around specific design needs, construct...

Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages children in...

Take your class on an out-of-this-world adventure with this fun engineering design lesson. Working in small groups, young scientists design, build, and test crew exploration vehicles using some creativity, teamwork, and an assortment of...

Class members work in pairs to build a catapult to launch a grape a given distance. The catapult project, a compound machine, reinforces pupils' understanding of simple machines.

Building a solar oven is always an enriching and engaging activity when your class is studying forms of energy or alternative and renewable energy sources. This lesson plan refers you to the re-energy.ca home website for specific...

Teams take their cavern designs and build a model from clay or paper mache that can be buried in sand. Testing involves dropping a bowling ball on the buried cavern. Teams dig out their cavern, inspect it for damage, and consider...
