Air pressure concepts explained visually
See flying toilet paper, shooting smoke vortex rings, exploding balloon dogs, tea bag rockets and much more!
Students will find out all about air pressure in this fun science show with strong curriculum links.
As this show is primarily about pressure and air it can be tailored to demonstrate how weather works or how planes fly; just let us know which area you would like us to cover on booking this science show.
When presented as a show on the weather:
- What is air pressure? Why are low and high-pressure areas important?
- How are clouds formed? What is our atmosphere made of anyway?
- What conditions are needed to cause tornados?
- What causes drought and how can scientists help?
Students will gain an appreciation of meteorology and gain insight into how our climate operates.
Stage 1 students can attend, however, in such cases it would best run over 40 minutes due to their limited attention spans.
When presented as a show on flight:
- How do pressure differences relate to flight?
- What is the Coanda effect and how is this important for the design of plane wings?
- Specifically, the show demonstrations are designed so that students will understand 4 basic forces acting on flying objects; lift, thrust, drag, and gravity.
|Air vortices||Shooting compressed air rings over the class – discussion on pressure|
|Bernoulli balloons||Try to blow the balloons apart – explains how air acts on surfaces|
