• Important Information

  Nothing for now...

1. We watched the rube goldberg videos from each period and students voted on their two favorite videos. Mr. Kleiner will tally up the votes and announce the top two videos from each class soon.

2. Mr. Kleiner showed a demonstration of convection. A tube of water with food coloring at the bottom was put on top of a bunsen burner. The heat from the flame caused convection currents to form in the water and these currents were visible because of the food coloring.

3. Mr. Kleiner explained how a bunsen burner is very hot above the flame, but very cool even just a millimeter to the side of the flame because of convection. Students were able to witness this themselves by experimenting with the bunsen burner.

homework: eat turkey or tofurkey

1.   We took a quiz on chapter 22

2.  Mr. Kleiner gave a boring lecture on convection, conduction, and radiation.  The class was shocked to learn that every person and every thing is emitting electromagnetic waves constantly.
