Arthropods
Movement
1. What does the word arthropod mean? How does an arthropod move? What do all subgroups have
in common when it comes to movement? Are there any differences?
Obtain Energy
1. What is their body design (bilateral, radial symmetric)? What does this tell us about food getting?
2. How does it get its food?
3. What kinds of things does it eat? (a couple common examples)
4. Where does it digest the food?
Reproduction
1. Do they asexually reproduce, sexually reproduce or both?
2. What is most common?
3. Explain the process of metamorphosis. Describe the process of molting.
Protection
1. How does an arthropod protect itself? Give some examples of unique adaptations also.
Environmental Connections
1. How have mysid shrimp affected the Great Lakes? What is ballast water, and how is it a part of the
problem?
2. What effect has global warming had on icebergs? What effects do these changes have on the ocean
water? How might that affect organisms like krill? Why?
3. How were arthropods in the salt marshes affected by the BP oil spill? Although serious to living
organisms, many survived. Why?
4. What have scientist learned about spider silk? Name some ways it might it be used in the future to
help humans. Why is it a good choice for these ideas?
Echinoderms
Movement
1. Does an echinoderm move? Explain water vascular system. Explain tube feet.

Protection
1. How do echinoderms protect themselves?
Environmental Connections
1. What have scientists learned about sea cucumbers and sea urchins? Explain why. How might these
concepts be used to help humans in the future?
2. How might global climate change affect echinoderms ability to “beat the heat”?
3. How do echinoderm shells affect global climate change? Why?
4. How did the brittle star get to the Atlantic Ocean? What kind of effect is this having?
