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? Pop can lids and expand balloons... + many others!

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

This performance can also be viewed as a LIVE web conference anywhere in the world!

Properties of Materials Liquid Nitrogen Show
Demonstrations

Safety of cryogenic substances  Liquid Nitrogen is - 196˚C, so what equipment must be used?
Fog breath Is water 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

PPS1.4 identifies and describes different ways some forms of energy are used in the community
...proposes ways of reversing a change of state after observing how some materials are changed by heating or cooling e.g. ice - water - water vapour.
...explores and describes how pushes and pulls can make things move

PP S2.4: - identifies various forms and sources of energy and devises systems that use energy.

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

Fits within COGS Unit 'Physical Phenomena

- Maximum of 60 students per session
- Two tables in a well ventilated area.
- Chairs are not required.
- Duration 45 minutes
- Set up time 30 minutes and pack up time 30 minutes

Cost

Specific Outcomes

Physical Phenomena: A student...
Liquid nitrogen bubble volcano!
Laser through condensation cloud
Liquid nitrogen over a balloon

This performance can also be viewed as a LIVE web conference anywhere in the world! The cost for video conference sessions are $110 inc. GST and can be arranged with our office.

For schools outside of Sydney please contact us to discuss how this workshop can visit your school as part of a regional visit

Unlike others we don't charge per student as we know that this causes an additional administrative load on your school office. Most schools tend to fill the workshops based on our recommended maximum number of students. If you have any questions please contact us.
