Learning Intention: Understand the motion of objects in terms of gravity, magnetic and electrostatic forces, bouyancy, friction and surface tension.
Success Criteria: You will be able to describe how things move using simple combinations of forces. For example, “A boat floats because the bouyancy forces are greater than the forces of gravity”.
Year 7 students have started a unit of work about how forces can:
- Start motion
- Stop motion
- Change the speed
- Change the direction
- Change the shape of objects or
- have no effect at all.
Your task is to produce a concept map using bubbl.us, showing contact and non-contact forces, including pictures as examples of each force. I have used “Arthur’s Clip Art” to get some free images to illustrate each of the forces. You could also use “Fotopedia” or “Creative Commons Search” to find images free from copyright restrictions.
