  2. Using ‘Tracker’ software in teaching mechanics

  3. Practical Work • Air Tracks are traditionally used to teach the physics of motion. However, • they often do not work well • pupils don’t relate this equipment to the real world • Having 30 students around the equipment isn’t easy • An alternative is to use free Tracker software and ask students to record and analyse examples of objects in motion.

  4. Tracker is a free video analysis and modelling tool built on the Open Source Physics (OSP) Java framework. It is designed to be used in physics education. Download from this site. When you do, take the sample experiments too. www.cabrillo.edu/~dbrown/tracker

  5. Getting started • Install the software then watch the two videos: • http://www.youtube.com/watch?v=tNCTuqR6NdM • http://www.youtube.com/watch?v=xds1ros43xM • These use a film clip that comes with the download. Easy for you to copy what is done in the videos.

  6. Working with students • The powerful approach would be to get them to film motion and analyse it. • Mobile phones or flip cameras could be used. • The motion needs to be controlled and within the vision of the camera. It is best to avoid panning the camera – the software can cope with it but it adds complications • How about … • Two people tapping a football to each other • Someone shooting a netball into the net

  7. Other ideas • Use a ‘pull-back’ racer (very cheap from Hawkins Bazaar) and film it alongside a metre rule. Track parachutes or spinning paper ‘helicopters’.

  8. Have some fun … • Track a whoosh bottle on a skate board!

  9. Have some fun…. There’s some great physics in Angry Birds! http://www.youtube.com/watch?v=iBrxjRDO0Zk

  10. Want more help? • If you can see the potential of using Tracker but want more support, contact Sarah at KSRC. • Sarah.Luckhurst@kent.gov.uk • 01795 476868 • She will arrange for a consultant to visit you with laptops loaded and ready for you to have a go with Tracker.
