Format
Time is allowed throughout the workshop to ask and answer questions. We treat video conferences in the same format as traditional science incursions.
1. Program begins with a general introduction and discussion on timezone and weather differences between Australia and your school
2. We discuss liquid nitrogen's temperature and perform a number of demonstrations on gas expansion on heating.
3. Your class now performs the 'expand air' experiment using simple materials supplied by you. Please refer to the supporting .pdf document supplied to you on booking
4. We perform a number of cooling experiments.
5. We discuss the pre-class activities 'supercool water' and 'freeze lettuce' with your class. Please refer to the supporting .pdf document supplied to you on booking
6. We perform demonstrations based on current research using lasers and superconductors.
7. Time is allowed for further questions and discussion of cultural differences.
Objectives
The student will:
- explore changes in state from solid to liquid to gas with a variety of materials when heated or cooled
- understand that gas pressure changes by heating or cooling
- learn about basic cell theory
- learn that an object must push one way to go the other way (Newton's Third Law of Motion)
- engage in a discussion carbon dioxide and it's possible effects on global warming
- develop an appreciation for research into superconductivity and its implications to future energy consumption
