Earthworm Observation

Scientists in Ms. Martin's class worked very hard to complete an observation this past week. We worked on creating a detailed hypothesis and then observed a worm in several different settings: Choice between wet and dry surface, choice between darkness or light, and reaction to "danger" ( vinegar on a Q Tip) We loved watching the worms move and were able to infer that they were able to move so easily/freely because they do not have a back bone. The students are very excited to continue our animal unit!
