Online Class for 9/30

Class on Tuesday, September 30th was an online activity. The activity showed weights, that you could attach to springs to see the friction that the weights caused. Putting heavier weights on the spring caused the spring to be more stretched out, and fall down faster. Having lighter weight barely moved the spring. On the website you could also change the softness/hardness of the spring as well as more or less friction. When I changed the softness and hardness of the spring I didn't notice much chance to the way the spring bounced. But, when I change the amount of friction it was very noticeable. If you put it to no friction the spring would bounce a lot, but with lots of friction the spring bounced once but then came to a stop. It was also interesting to see the different changes of the planets. If you changed the button to the weight in Jupiter the spring stretched out a lot. This website would be a fun way to show elementary children the ways of friction. It is a great interactive website.
