Well we are about done with our Genetics Disorders Presentations and will begin the next unit: History of the Earth and Lifeforms. I'll discuss more in detail in class about this unit. The homework for the beginning of the week is as follows:
Wednesday, March 3: Pretend that the entire history of the Earth was compacted into 24 hours. You will make a 24 inch strip of paper to represent the 24 hours. Where would you place the following?
- Single-celled organisms, called stromatolites begin to produce oxygen.
- First marine plants
- Jellyfish appear.
- Trilobites and creatures of the Burgess shale.
- Plant life appears and the first land creatures.
- Reign of the Dinosaurs.
- First Humans appear.
Have a great week,
-Mr. Pfiester
