Further Investigations: Worms

  1. Investigate other invertebrate phyla that are often considered “worms” or worm-like. How does their biology compare to the three invertebrate phyla discussed in this topic?
  2. Charles Darwin is famous for his foundational work in evolutionary biology in the mid-1800s. He also wrote extensively about earthworms. Use library and Internet resources to investigate the ecological importance of earthworms. Why are earthworms considered “ecosystem engineers”? How many species of earthworms occur on Earth? How do humans interact with earthworms?
  3. Design and construct an earthworm composting bin. Use library and Internet resources to investigate the conditions needed for breeding earthworms in captivity (called vermiculture). Examine how worm composting changes the physical and chemical properties of compost material over time.
