A safe surf rated website. Web surfing without surprises
See flying toilet paper, shooting smoke vortex rings, exploding balloon dogs, tea bag rockets and much more! Students will find out all about pressure in this cool science show!

Concepts covered:
What is air pressure? Why are low and high pressure areas important?
How does pressure differences relate to flight?
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, as well as understand 4 basic forces acting on flying objects; lift, thrust, drag and gravity.

How Air Affects the Weather and Flight

Syllabus Outcomes: Science and Technology

Earth and its Surroundings

A student:

ES 2.6: identifies some of the features of the solar system and describes interactions that affect conditions on Earth.

ES 3.6: recognises that the Earth is the source of most materials and resources, and describes phenomena and processes, both natural and human, that form and change the Earth over time.

Physical Phenomena

A student:

PP S3.4: identifies and applies processes involved in manipulating, using and changing the form of energy

Fits within COGS Unit 'Local Environments'.

This performance is authorised by the
Performances for Schools program, managed by the NSW Department of Education & Training.
Shooting vortex rings over the audience - how do they work?
Exploding the balloon dog! Contained air has pressure.
