Unit 5 Part 2

Today was AWESOME, we had one of the coolest/most fun activities I've ever done in school. We got to make a massive slip and slide about 35ft long. This slip and slide help to reduce our friction and thats why we were able to slide so far down. When I went down when it was dry i only slid, maybe 5 feet. This is because without water or soap the slip and slide is just like normal ground. Now with water and soap added this helped to reduce the amount of friction by a lot and thats why Jonas and Candace could slide all the way down! This wasn't the only cool thing we got to do today though. We also got to play with frisbee disc things that basically made the entire ground like an air hockey table. Most of them didn't work but a few did and those things were nuts! They would slide across the entire floor no problem. This is because they were reducing the amount of friction between the bottom of it and the floor by pushing air out of the bottom. Mr Blake said that at Kam they can do it across the entire gym floor which I thought was pretty cool!

Although this was very fun we also had to learn a great deal today in class and had our lab practical which was pretty confusing. The lab practical was on forces, friction and tension. Although we were adequately prepared the lab still confused me because we weren't allowed to see the spring scale so I kept doubting my equations and answers.

Interesting fact of the day:
If a bus and bicyclist collide the both hit each other with the same amount of force. Although the bus and bicyclist hit each other with the same amount of force the bus is to beast mode (it just has more mass) and will plow through the bicyclist.

This is Kelli playing with the cool air hockey puck fancy things that reduced friction, awesome.
