Teacher Angelica Brown at Glennallen sent in the following report:

"In Marine Biology students are learning about the variety of marine life and how it is classified through taxonomy. As you work your way through the different phyla, organisms become more complex. Focusing on phylum annelida, segmented worms, students observed the simple form and function of the internal and external anatomy of an earthworm. 

"While there are no earthworms in the ocean there is a variety of bristle worms and tube worms with a varied form of body function. Students then moved to phylum arthropoda and dissected a crayfish. This is the largest phylum which includes insects, spiders, and crustaceans. Students learned about the function of the exoskeleton and digestive glands and wondered why the stomach was in its head!"
