Both the National Science Education Standards and Benchmarks for Scientific
Literacy propose standards or goals for understanding big ideas in evolution
starting in the elementary grades. Of the ideas addressed in Session 5
(variation, genes, mutation, adaptation, natural selection, artificial
selection) and Session 6 (species, evolution of new species, relatedness,
common ancestry, tree of life), which do you consider appropriate to
introduce at the grade level you teach?
Variation, genes, mutation, natural selection, artificial selection, species
evolution of new species, relatedness, common ancestry, and tree of life.
I can see ways to show the children variation in the life forms around them.
They can then understand that there are genes that control this. My
student already has been introduced to DNA from a museum in Atlanta Georgia.
He can understand mutation, from this understanding.
Natural selection - he saw something from the TV show about the rabbits and
asked about it. I was able to teach it because he was inquiring. Hey -
this is great for my research!
I think that all of the subjects are on his level, if he is inquiring. I
just need to learn how to stimulate him to inquire about them. I don't know
how to explain the difference between individual adaptation and a population
adaptation over time. So I am not sure he could learn this, since I struggle
