Your whole life you have been living around many forces, and you have constantly seen things in motion. You have even been the force that caused a lot of the things around you to move. Friction is a force that slows things down. For example, if you slide a paper across a flat. smooth surface, there is not a lot of friction so the paper can go farther, but if you try to slide a paper across a bumpy surface, it will not travel far. Friction can be a good thing and a bad thing.

Explain one real life example where friction is a good thing (stopping something from moving that needs to stop) and explain one real life exmaple where friction is a bad thing (stopping something from moving that needs to move). Think deeply. I want to hear your excellent examples!

Students remember to explain BOTH sides of friction (good vs. bad) and comment on someone else's comment. You may agree, disagree, or add to what they are saying. I look forward to the discussion.

Parents, other classes, and  other teachers are welcome to participate as well. We love to hear everyone's ideas! If we all work together, we could really get a great discussion in MOTION!
