Class Update

Monday, March 29th. All about Gears. That was our topic today. We looked at the difference between pinion gears and spur gears, how gear ratios will affect the power and speed of their vehicles and how wheel size can have an impact as well. We looked at the How Stuff Works website on gears for more information and demonstrations. http://science.howstuffworks.com/gear-ratio.htm Check it out. Tomorrow we will work on our cars again. We are still gathering materials for building our cars and wheels to use as well. No Homework this week. Grandparents day on Friday as well.
