a mechanism that uses moving air to make things happen

Exploring pneumatic systems

Design and technology

This unit introduces pupils to creating movement with air using pneumatic mechanisms. They will then apply this knowledge to develop a moving toy.

Physical activity and equipment requiring safe use

Use of ingredients which may contain allergens.

Risk assessment required - may contain allergens

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.

Air pressure can be affected by temperature, elevation and ...

The connector splits the air into two paths.

The pressure builds up and causes the output plungers to move.

Order the actions in this simple pneumatic system.

Which would fill the balloon in the output the quickest?

Which word beginning with the letter 'i' means to make something bigger by filling it with air (or gas)?

Air __________ is the force of air pushing against a surface.

The air pressure **outside** a balloon is __________ the air pressure **inside** the balloon.

Which of these would **not** be inflated or made using air directly from our lungs?
