Biology 11

Today we had a quick quiz on Evolution and Natural selection.  Next we looked and genetics in more detail with Punnet squares.  Make sure the genetics review gets done for homework. 

Science 8

Today we wrote a quick question quiz.  Next we watched a Bill Nye video on cells......and then we built our own plant or animal cell from crafty things in the classroom. 

Science 9

Today we had a quick question quiz.  Next we took some notes on matter: pure substances and mixtures.  Then we went to the IT lab and started some research on "This Week in Science" presentations that we will start next week. 

Science 8

Today we practiced using microscopes and determining actual size of organisms.  We started by taking notes about cells and cell theory.  We did a big lab on cells by looking at our own cheek cells under a microscope.  How cool is that!   Make sure you finish the lab and the venn diagram on prokaryotic and eukaryotic cells. 

Biology 11

Today we worked on the Natural Variations lab and turned it in with three graphs (length of beans etc.) next we took some notes on DNA and genes and watched a video on the evolution of human skin colour.   Finally we did a lab looking at our own genotypes and phenotypes called Variations in Human Beings and turned that in. 

Next class you have a short quiz on evidence for evolution and how natural selection works. 

Biology 11

Today we review the answers to the peppered moth case study.  Next we measured wrist circumference, grasshopper femur lenght and bean seed length in the Natural Variations Lab.  Three graphs on the same graph paper should be completed for homework. 

Science 9

Today we added two more things to our knowledge of subatomic particles:  ions and isotopes.

We completed an atomic structure review worksheet and then looked at a website:  how to build an atom
