1.In 6.1 I learned that different surface types can have friction force. in 6.2 i learned thatthe more mass something has, the more friction force it will have. in 6.3 i learned that different surface types have different amount of friction force.
2.You use a "spring scale" and pull it across a surface.
3.I learned that you should only change 1 variable at a time. there are many variables you could change when you are testing something but if you want accurate data, you only change 1 variable at a time. a variable is something that can be changed.
