Tuesday's Blog

Wow we got used to some levers today. I really liked all the examples of different levers. This is way better than just showing students a picture of each example. When they actually had the lever in front of them they could play with it and experience what part is the pivot (fulcrum) and which part the force is applied and resisted. I also liked the tip of which was is the middle (fulcrum, F(effort), or F(resistance) )would determine if it was 1st, 2nd, or a 3rd class lever. I think tools like this are very important to present to our students, because even as obvious as something may seem to you, it may not be apparent to others.
