 - We have three 6th grade Science classes and two 8th grade Science classes blogging here from the Pacific Northwest in Chimacum, WA! Sixth graders are learning a bit about Mt Saint Helens, environmental science through fresh water ecology, and physical science this year. Eighth graders are learning about life science this year. Please join us as we learn Science by exploring our world. Mr. G's Blog Mr. G's Class Facebook Page

Friction Force
What have you learned about friction in lesson 6, Inquiries 6.1, 6.2, and 6.3?
6.1: I learned that if you slide a block across a rough surface there is more friction.
6.2:I learned that if there is more weight that your pulling then there is more friction force.
6.3: I learned that if you change the surface area then the friction force varies.
How did you measure sliding friction in the labs you did in class?
We measured the sliding friction in newtons.
What did you learn about controlled variables? Give examples of how you controlled variables during your labs.
I learned that controlled variables are things that you don't change during your test. In our labs we kept the sliding speed the same in all of the labs. Controlled variables are things that you do not mess with.
