The last two days in class were spent discussing and investigating chemical and physical changes. If you missed class you can catch up on these concepts with the two videos below.
With our test last Friday our evolution unit is complete. Monday we begin our Chemistry Unit which will take us up to Winter Break.
Gold Tape Question: Read THIS ARTICLE about how elephants are continuing to evolve and write a short summary about: 1) What adaptation is occurring in the elephants? 2) What is causing this adaptation to rise in the population? 3) How does this adaptation help the elephants survive? 4) How do you think African elephants might look in 10, 20, or 30 years?
Today was day one of two investigating other methods of relatedness among organisms. So far we have focused on how organisms that are similar to each other tend to look similar. However, there are many other ways to compare relatedness including homologous, analogous, and vestigial structures as well as the type of cell that makes up an organism. Tomorrow we will share out what we've learned with our partner groups and continue our discussion of relatedness among all organisms.
