CHEMISTRY: Great job learning to name binary ionic compounds – and even beginning to write formulas! Next Tuesday, let’s add polyatomic ions! Whoot, whoot!!
Speaking of formulas, what is your plan for all the memorization in this chapter? Word of warning – don’t wait to the last minute!!
Super important – the secret for the next few days and this entire chapter is DON’T GET BEHIND! Keep up with me and practice, practice, practice!
PHYSICS: Who knew snow skiing could be so complicated! Well…friction problems on an incline anyway. Here’s the problem 49 from the homework and then our discussion of friction problems on an incline.
Back to the problems – remember, drawing the diagram is super, super important. Label all the forces and apply the concepts you know about net forces and resultant forces – let it tell you a story. 🙂
