Performances for Schools program, managed by the NSW Department of Education & Training.
Demonstrations

Safety of cryogenic substances  Liquid Nitrogen is - 196˚C, so what equipment must be used?
Fog breath Is moisture present in your breath? Condensation demonstration
The shrinking balloon What happens to gases when rapidly cooled? Air pressure demo.
Balloon blow up Blowing balloons up from the outside! Transferring heat energy.
Lid launcher  Expanding gases have a lot of force - why can this be a problem?
The flying glove Heating gases causes rapid expansion!
Ball smasher Why can rubber shatter? Glass transition phase demonstration
Banana hammer   Can plant material survive instant freezing?
Liquid Nitrogen sprinkler! Rapid expansion of Nitrogen can be utilised - what about water?
Cool lasers How are lasers used in atmospheric research?
Frozen bubbles Bubbles can give clues about our changing environment.
Cooling circuits Proving chemical reactions slow when cooled.
Leidenfrost effect Rapidly boiling liquids can hover over surfaces… how?
Levitating magnets See the power within superconductors; future research in action
Specific Outcomes:

A student:

4.6. identifies and describes energy changes and the actions of forces in common situations

4.7. describes observed properties of substances using scientific models and theories

4.8.1.(a) identify that living things are made of cells

5.6. applies models, theories and laws to situations involving energy, force and motion

5.7. relates properties of elements, compounds and mixtures to scientific models, theories and laws

5.8.1 (a) explain that systems in multicellular organisms serve the needs of cells
Find out how solids, liquids and gases change when rapidly heated and cooled. Smash a squash ball! Shrink a balloon instantly!
What happens to living things if they are frozen?
How can Newton's 3rd Law of Motion explain a
liquid nitrogen sprinkler?
Explore Charles Law using popping cans and expanding balloons.
Investigate the Meisner effect using levitating superconductors.
Just what is the Leidenfrost effect anyway?

Covers phase changes, expansion and contraction, basic cell theory,
air pressure and the weather.
