Biology Co-op 10/16

 I didn't post this yesterday, because I was overwhelmed, but here's what we did for the biology class that I teach on Friday mornings.  It was a great class.  The boys were actually listening and enjoying it.

Bacteria and Viruses (reference: BJU Life Science textbook)

Thylacine

  • We learned about the Thylacine or Tasmanian Tiger, an extinct marsupial from Tasmania/Australia
  • We watched videos of the last Tasmanian Tiger from 1936
  • We discussed what led to its extinction
Bacteria
  • Bacteria structures, size
  • Bacteria types
  • How bacteria help the environment
  • Can you see bacteria with a microscope?
Viruses
  • Viruses are not living organisms
  • Virus structure
  • Video of a virus attacking a cell
  • You can only see viruses with a special microscope
LAB
  • Using 10 Petri dishes with agar and 10 cotton swabs, the kids swabbed various surfaces (including a toilet seat, doorknob, cat's paw, cat's water bowl) and then created streak plates.  I'm keeping the Petri dishes in a warm place until next week when we can compare/contrast bacterial and fungi growth on the plates.  Maybe we can take some small samples, form slides and try to identify bacterial shapes under the microscope
