First dissection day! In class the students have been studying both the external anatomy and internal systems of the earthworm. They have looked at characteristics that has put this animal in the phylum Annelida meaning ‘ringed’ or segmented worms. After removing the reproductive system, the children observed the 5 aortic arches, dorsal aorta, and the digestive system. They were impressive by displaying proper lab procedure, technique and engagement!
