What I Learned Today: Worm Sort

For the worm sort, I looked at four different types of worms. Each worm belongs to a classification. The worms I looked at were: Lumbricus earthworm, aempais leech, polynoe scale worm, calcareous tube worm. The classifications that they all could belong to are the following: Flat worm, round worm, tape worm and segmented worm.
