This weeks lesson on Developing Experts is the last lesson on Forces and Magnets. It looks at what happens when an object moves on different surfaces.
1. Watch the Mission Presentation about Forces.
2. read the Rocket words and explain to someone what they mean.
3. Have a go at the Mission Assignment. How quickly does a toy boat take to go down a ramp that has different surfaces?
If you haven't got a boat, a smooth bottomed object would do. See the instructions on the presentation or on the sheet.
