 sabastians blog- 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
1. i learned that friction is the force that happens when 2 surfaces rub together, like a block and sandpaper.you can measure friction in many ways, including newtons and LBS.

on narrower sides, theres more weight since its a smaller side, so its harder to pull, which means there's more friction.

2.we measured friction by pulling the block with a little scale thing, and it measured the force it takes to pull it with newtons by feeling the drag the block creates.

3. controlled variables are the thing that when you do several experiments, it stays the same. we controlled: pulling speed,pulling length, and block type.
