These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- A buggy chassis provides structural support for all the components.
- A chassis must be strong enough to enable the buggy to function reliably.
- Visual inspections can help identify and fix issues before they become problems that are harder to fix.
- Motors can be controlled through code to change the direction of a buggy.
Keywords
Chassis - the base frame or structure that supports and holds components
Strong - able to withstand force, pressure or wear
Visual inspection - looking at something carefully to see if you can find any problems
Common misconception
As long as the components are attached the buggy will work fine.
A good chassis design isn’t just about holding parts. Care should be taken when positioning and securing components to ensure the buggy is reliable, easy to fix and functions as intended.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
