Bacteria on Cells

Here is a sample image from one of the mouthwash-rinsed mouths:


It was difficult to find cells in some of the samples (perhaps another variable in the experiment?) but those that were present looked a lot like the one above.

Remember to answer all discussion questions and read ahead on diffusion in the textbook.

Welcome, KIPPsters!

Hi everyone,

We have created this blog for you to be able to communicate with your science teachers effectively. We will be sharing websites, links, homework hints, and assignments here to help you stay organized for the rest of the year.

To begin, here is the cell model website described in class:
