Whoops! I meant to come straight home and post yesterday, but it was my son's 7th birthday and I forgot. So, let's see what I can remember . . .
I do remember that the O section completed the marble roll lab with flying colors. Groups in the O-1's that were not so stellar last week did admirably this week. We will have to go over it on Monday to make sure everyone understands the graph of velocity and the graph of acceleration.
The L section wrapped up lesson 6-6 discussing Newton's three laws. This lesson is discussed on Day 84. I did a good job with the candle in the bottle demo. Mrs. Nolan had to take over to make sure I didn't pick favorites for volunteers. I don't think I do, but everyone said I did. I should leave this up to Scottie every time (Scottie is my virtual seat picker friend, Scottie Pippen--you will have to ask your son or daughter if you don't understand this).
The W and S sections discussed momentum. We watched a short video, then went over HW using the new OWLSbuck/Scottie Pippen reward system. Then I got out the super ball swinger momentum display device. This allows me to show that momentum is conserved. I swing one ball in and one goes out. I swing two balls in and two come out. In a creative burst I tried marbles on a marble track from lab and discovered that the same thing happens with them. If they are in a row and I roll one in, one comes out. Two in, two out. Momentum is mass x velocity, so it has a direction. In a closed system, it is conserved--as long as no outside forces are allowed to interact.
Next up is a review day, followed by our test. Then, at the end of the week, we have our big vocabulary test. I hope that everyone is studying!
Sweet justice.
