Hey 7th graders- this is the first week review. Now, blog entries will not be daily, but weekly, so you have to check at the beginning of the week. Anyway, here is what we did in 7th Grade Science this very short 3 day week:
Monday: (No School- President's weekend).
Tuesday: We talked about Skye and Poppy, and their offspring. We learned that each parent gives one gene to their offspring. We also learned about dominant and recessive traits. A dominant trait is the one that basically has 'more say'. For instance, if the dominant trait is blue, and the recessive trait orange, and if you have one blue and one orange trait, you would get a blue [tail]. See SmartNotes and "Critters Template" for more info.
Wednesday: More genes (see above).
Thursday: Punnentt Squares, see SmartNotes and "Punnett Squares--Step by Step" handout for more information.
Friday: (No School- Snow Day!)
TERMS YOU NEED TO KNOW
Alleles: Versions of a trait
Phenotype: Physical characteristics that are visible
Genotype: Genetic information (alleles) for a given trait.
Homozygous: same alleles
Heterozygous: different alleles
That's all for this week! *See SmartNotes for more information!
