In this 5 lesson project, students will begin by learning about forces, motion and Newton's Third Law. Using this knowledge, students will embark on a creative journey to design and 3D print their own functional, balloon powered dragster! Their aim is to create a vehicle that can travel as far as possible in a straight line and in the final lesson, they will compete against each other using their own unique dragsters. Enrolling in the lesson will give you complete access to the teacher training material and lesson documents. This includes content to help you prepare and deliver the lessons along with design tutorials so you become familiar with the process prior to teaching it in the classroom.

Subject Areas

The lesson can be incorporated into the study of physics, maths, computing and design technology and can be adapted for ages 7-16.

Learning Criteria

In this project students will:
- understand the principles of Newton's Third Law
- develop an understanding of forces including air resistance, friction, thrust and gravity
- understand and explore mechanical concepts of wheels and axles
- use their knowledge of forces and wheels to design a balloon powered dragster using CAD software and 3D printing
- analyse the performance of their balloon powered dragster by measuring the distance it can travel
