 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

The force of friction Controlled variables are measured by,
How far we pulled the blocks
How fast we pulled the blocks
The surface type
Manipulated variables are measured by
Surface type
Weight

Surface area I learned that different surface types make more/less friction, they don't all have the same friction measurement.
I learned that the more weight on a surface type will make more friction because it is heavier.
I learned that if you put more surface area on a surface type the friction stays almost same!

When you pull a block across why does it measure friction?
It measures friction because when you pull a block across a surface area the friction goes the opposite way!

Thanks and 6.1 i learned about surface area and that different surface types make more/less friction, they don't all have the same friction measurement.
6.2 i learned that the more weight on a surface type will make more friction because it is heavier.
6.3 I learned that if you put more surface area on a surface type the friction stays almost same!
