PHYSICS: Wow! Do you realize what we just did? We finished the chapter! Well, we’ll add this small lecture on simple machines from chapter 7 to the chapter 5 test – but we’re done! Did you remember this stuff on simple machines from your physical science days?
I don’t think you’ll have any trouble with efficiency and mechanical advantage problems. How do you think the efficiencies of machines compare? Could you design a method to test that? You don’t need no stinkin’ lab sheets! Do you?

Ms. Skinner- I don’t think I’ll be able to make it to the help session tomorrow-is there any way you could record it and post it? thank you!
May we have a list of the labs due Wednesday? I know most of them but I’m not sure what to title a few of them since they were of the create-your-own variety. There are six labs, two create-your-own and four PDF link-y ones, right?
❏ Inertia Balance
❏ Coefficient of Friction
❏ Forces (Car acceleration)
❏ Power
❏ Equilibrate Forces
❏ Machines and Efficiency
+ roller coaster
(I’m guessing forces is glx?)
Also, what exactly do we need to put in for the power lab?
