	Published by Australian Academy of Science
Activities \| A fair cop! Accurate breath analysis and speed detection

Patrick Gormley (Science Resource Center, USA)
- Alcohol breath analyser demonstration
Mobile Inquiry Technology (The Concord Consortium, USA)
- Calibrating thermometers
Science and Mathematics Initiative for Learning Enhancement (Illinois Institute of Technology, USA)
- Straight line motion in two parts
- Linear motion: Speed, velocity and acceleration
Mississippi State University (USA)
- Sonic doppler effect – students can watch an animation of sound waves that originate from a moving source.
- Doppler effect, 2 sources – animation shows sound waves from two moving sources.
Note: These activities require Shockwave.
Kettering University (USA)
- The doppler effect and sonic booms – describes the Doppler effect, the sound barrier and supersonic speed, using simple animations.
Hands-On-Physics (The Concord Consortium, USA)
- Mechanics – provides background information on the measurement of speed, together with a number of activities.
Center for Research on Parallel Computation (Rice University, USA)
- Rocket racer – students construct a 'car' and decide how to measure its speed.
