Science Week of 3/1/09

MONDAY:

On Monday, Mr. Finley said that our previous quiz had some errors on it. So we got toy cubes for our table. We started out with 6 cubes and did meisos with them. This is how we did it...

1) Double the amount of cubes

2) Pair all the cubes

3) Split the pairs

4) Split them again (you should have 4 groups of 3 cubes)


Tuesday:

On Tuesday, we did a simulation that was based on Mendals pea genetics experiment. It showed us how when you combine 2 genes, almost all the time, the outcome will be different. We also learned about recesive and dominate genes. A dominant gene is stronger than a recesive gene.

Wednesday:

We learned that each letter in a gene is an allele. If you have two alleles that are the same in your genotype or genetic code, it is a homozygous. It you have 2 different alleles than it is considered a heterozygous. We practiced a little of this through that night homework.

Thursday:

Fin was gone for Wed. and Thurs. so we had a sub. basically, we reiveived the homework and started a lab.

Friday:

Mr. Finley was back!!! We picked up the lab that we had started. We also tasted something called the PTC taster. If your taste buds were like this, you could taste a nasty bittery taste. I did taste it. If you didnt taste anything. It tasted like plain old paper.
