1 quiz next week, Tuesday

We have two quizzes coming up next week:

• Gears, Pulleys, Sprockets (2nd and final)
• Simple Machines (3rd and final)

The simple machines one will test mechanical advantage, efficiency, and the descriptions and attributes of the simple machines with a focus on types of levers.

I did not hand back your 1st gear quiz, that was my fault, so we will not quiz on Monday.  I need to return those first before I give you a second.  It's only fair that you should see what you did the first time so you may improve.  Tuesday we will do both quizzes.  Take advantage of the PPTs on Its Learning, and activities 1.1.2 and 1.1.5 for practice problems and answer keys.

Enjoy your weekend!
