Student will be able to list major characteristics of nematode, annelids, and platyhelminthes and will be able to give an example of each.
Younger students: Draw a picture of a particular species of nematode, annelid, or platyhelminthes and use the biodiversity website to explore the animal's taxonomy.
Older students: Fill out an animal report form (this one from CurrClick is free and will work for this activity), making sure to include the characteristics that make this animal a nematode, annelid, platyhelminthes. Use the bio-diversity website to explore the animal's taxonomy.
