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
- The air inside the bottle forces air into the balloon which expands.
- Air inside one syringe is forced through the plastic tubing into the other syringe, which is forced to open.
- If one syringe is a different size to the other, the amount of air in the syringes affects the movement.
Keywords
Pneumatic system - a mechanism that uses moving air to make things happen
Input - something put into a system
Output - something that comes out of a system
Common misconception
Air can only be directed to one place (output).
One input can affect multiple outputs by splitting the flow or direction of the air.

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.
