By investigating how friction, including air resistance, affects motion, I can suggest ways to improve efficiency in moving objects.

SCN 2-07a

Benchmarks:

· Describes friction as a force which opposes the motion of moving objects, for example, two solid surfaces rubbing against one another or a solid surface moving through air or water.

· Finds an association between air resistance (drag), the speed of the object being investigated and the surface area exposed to the air, making links to original predictions.

· Demonstrates understanding of how friction and air resistance can both be useful, for example, in braking systems, and also a problem, for example, causing moving parts to wear.

· Describes efficient movement as that which requires the least possible energy and suggests ways to improve efficiency in moving objects, for example, by streamlining.

CD Hovercraft

This activity demonstrates what happens when we reduce the level of friction and object experiences.

Without the air the CD experiences a higher level of friction and doesn't move far when pushed.

When the air is released from the balloon it creates a layer of air between the CD and the surface reducing friction, as a result the CD can travel far further.

Note that bottle lids can be attached with blue-tac rather than super glue.
