1. I learned that when you pull one surface on or through another surface you cause friction to pull the opposite way so it slows down and will eventually stop.

6.1 I also learned that if the weight is greater it increases the friction

6.2 If the surface is smaller it also increases the friction

6.3 some objects or surfaces increse or decrease the frictions pull.

2. We measured sliding friction by pulling a block along by a spring scale which measures friction because friction pulls backwards and so, if the block is harder to pull, that much friction that is making it harder, so that is how we measured it.

3. we controlled variables by changing one thing, such as the weight, and then kept all the other things the same, slope, times, length of pull, surface area, surface type, etc.

My Classes & Students

 Period 1 Period 2 Period 3

I started my teaching career in South Central Los Angeles teaching in modified to full bilingual 4th and 5th grade classes. Then I moved to WA State where I have taught mainly 6th through 8th grade. I have enjoyed the culture clash but notice that kids are the same everywhere :o)

My areas of interest are science and technology but I also love studying ancient cultures and learning about different peoples and cultures.
