Biology 11

Today we did two labs looking at Bacterial colonies.  The first was staining E. coli and B. subtilus to see bacteria that are gram positive and gram negative.  That lab (Staining and Observing Bacterial cells) is due on Tuesday with questions completed.

The next lab was: Antibiotics and Bacteria.  We cultured our two strains of bacteria and added different types of antibiotic discs to see their effects on E. coli and B. subtilus

Science 8

Today we collected pond water and looked at it under the microscope.  We saw some cool stuff which we drew and then calculated sizes for.   Your cell diagrams are due on Tuesday.  They should be coloured and labelled.   They are found HERE and HERE.
