We began the week wrapping up the Simple Invertebrate portion of the unit with our quiz. On Tuesday we took the quiz and then started discussing the Mollusk and Annelid worm phyla, which are more complex than the previous invertebrates studied. We watched a couple video clips about Mollusks that showed how smart some of the organisms in this phylum can be. Later in the week, we began our external and internal exploration of earthworm anatomy (structures and functions).We learned a little about their body systems and anatomy, and we also learned important direction terms (anterior, posterior, dorsal, and ventral). On Friday, we put our new knowledge of directions and earthworm anatomy to work. We did a live earthworm observation lab. Students had the opportunity to observe a real earthworm's movement, structures, and they even had to test the earthworm's reaction to environmental stimuli(being placed on its dorsal side, dry/wet paper towel, and presence of food). A special thank you goes out to all of those who brought these earthworms for us to observe!
Students are getting quite excited about the earthworm dissection next week!!
