The last day of the marking period. Halfway. Whew!
I started pressure with the L and O sections today. It wasn't a terribly exciting class--a short video on why the Titanic sank, and then some time to work in class. It helped students get their HW out of the way.
In the W section we did the bouncy ball lab, a lab that explores the difference between how well different types of balls bounce. We used 8 different bouncy-type balls and recorded the height they bounce back up to after being dropped from 100 cm, 70 cm, and 40 cm. Then the students graphed their results and took the papers home to answer the questions on the back of the worksheet.
The S section did their second day on pressure, Unit 7. We went over HW, took notes, and worked on the next HW assignment. I showed a simple demo of a balloon in a bottle. There is a hole in the bottom and it makes for a magical thing, when the balloon stays inflated even though it is not tied off! Amazing to see.
Sweet justice.
