Math students came up with some good questions for a lesson about Prime and Composite Numbers. There are questions leading me to believe that some students already have a grasp on these numbers.
This was the image displayed to students.
These are the questions...
I wasn't sure about completing an onion cell and cheek cell lab in one 50 minute period, but the students were such good workers, scientists and listeners that we did it! Each lab has 4 students. 2 students set up a slide with a thin layer of onion cell and the other two students set up one slide with cheek cells. I dropped dye on each sample and students then placed the slip cover on the slide and took a look. After 7 minutes, I had students switch to the other microscope at their lab station and look at the other sample. They were taking notes and had to clean everything up before the bell. They did it!
