Simple Machines

I did not know that there was so much to learn about simple machines. I always wondered what a fulcrum was, and now I know. I also enjoyed the game. This is some of my favorite stuff to learn about. I also didn't know that a ceiling fan and a boat propeller were both inclined planes and it was also interesting to learn that shoelaces were pulleys. I hope how we can do this again very soon because this was very interesting. THIS BLOG ROCKS!!!!!!
