After we took our 'first' look at the unit test, we visited an observation lab to try and answer some questions that we still have about body systems and adaptations.
Today, we started comparing different adaptations. We compared bird bones, fish respiratory systems, and plant vascular systems. We got a good look at celery's xylem and phloem and learned how xylem takes water up and phloem sends glucose down from the leaves. We also checked out some chicken bones and saw how they were hollow inside.
Tomorrow we will be viewing the respiratory system of fish. We will see how the obtain oxygen from water and what the purpose of the the gills are.
After we wind this up we will be writing an essay over the differences in adaptations.
WE ARE ALMOST TO SPRING BREAK!!!
