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.

W HAT i lEArnEd AbOUt frIctIOn!
well we are supposed to say what we learned about friction.

lesson 1: i learned that different surfaces have different amounts of friction. the fine sandpaper has the most friction.

lesson 2: i learned that with more weight comes more friction. like if you pull 2 blocks, it has more friction than with just 1.

lesson 3: i learned that different sides of the block have different amounts of friction, but its not much of a difference.

we measured sliding friction by using spring scales in class. friction can be measured when it pulls back on the object you are pulling. so when you pull it, you can measure the resistance with a spring scale, and that is
friction and that is how you can measure friction with a spring scale.

we learned that controlled variables are important. plus also here are some examples.
1:distance pulled
3:surface type
5:block type
those are things that are controlled variables, which means they stay the same.

well, yep! thats it! bye!
