Roll With The Changes (Friction)
http://teacher.scholastic.com/dirt/roll.htm Roll With The Changes (Friction) Why do the tires on your bike roll better when they're all pumped up than when they're soft? And why do your roller blades go better on smooth pavement than on a sandy road? The answer is friction...the big rub! The force that slows you down and gets you going; without friction, you'd be slip slidin' away! |

Friction - 4learning
http://www.channel4.com/science/index.html Friction is a force that slows movement. It can slow your movement down the park slide (solid against solid), or swimming through the water (solid against liquid) or dropping with a parachute (solid against gas). |

Friction (4e)
http://www.standards.dfes.gov.uk/schemes2/science/sci4e/?view=get In this unit children build on their existing knowledge of forces and learn that forces can be measured and compared. The unit focuses on friction as a force which exists between objects moving across solid surfaces and opposes motion, and the forces of air resistance and water resistance which oppose the motion of objects moving through air and water. Experimental and investigative work focuses on: -deciding what evidence should be collected when planning and carrying out a fair test -making measurements using a forcemeter -looking for patterns in results, interpreting and suggesting explanations for these. Work in this unit also offers opportunities to relate knowledge and understanding of frictional forces to everyday contexts and to recognise that science provides explanations for familiar phenomena related to friction. This unit takes approximately 11 hours. |
