Unit 2 Newton's 2nd Law    


Anti-green: Must-Do, green: Should-DO, anti-red: Strive-to-Do, and anti-blue: extra help. 

All activities should be completed cooperatively with 1 partner, unless otherwise noted. 

Before asking Mr. Skapetis a question, you must ask 3 classmates your question.  If they do not sufficiently answer your question, then you may ask.  It's not that he doesn't want to help you, but this policy frees him to reteach and grade the steady flow of work.

If there seems to be a glitch in my system or thinking, please let me know so this can be a smooth process going forward.
