Today's Quote:
Recap:
The grade honors classes ran the cloud chamber experiment with disappointing results. We could not get the petri dish cloud chambers cold enough to create the vapor clouds for more than a few seconds so we only saw one or two alpha particle traces. I ordered a better radiation source and will do the experiment as a class demonstration when it comes in.
7th grade honors had better luck with the onion and cheek cell lab while learning staining techniques. The onion cells came out nicely with any students able to photograph them using phone cameras. Cheek cells were a little ore of a challenge, but still came out nicely with some pictures available.
8th grade science finished the definitions and electron placement worksheet for the periodic table.
Brain Bender:
While playing in the bathtub, Hardy Pyle decided to play with his two foot long plastic boat, which was filled with nuts and bolts. While playing, he accidentally tipped the boat over, dumping the contents into the water.With the nuts and bolts in the water, will the water level in the bathtub rise, fall, or stay the same as it was when the nuts and bolts were in the boat? Why?
Agenda:
8th Grade Honors.
Go over Homework. Redo and turn in on Tuesday for 1 letter grade higher. (ALL problems must be corrected for the extra points to apply.
Mixtures, Elements and Compounds
FYI- Get ready for your head to explode! How to determine Valence Electrons in the transition metals. You will need these two sites to help you:
