Mississippi Science ZOO.6.6
The Standard
- ZOO.6

What This Standard Means
What Students Need to Do
- Students research how sea stars regrow lost arms. They compare this process with human healing and explain what it might mean for medicine.
What Mastery Looks Like
- A student uses evidence from reliable sources to explain a possible medical use, such as improving wound healing. They make clear that this research has not shown humans can regrow arms.
Common Misconceptions
- Students may think any broken sea star arm can grow into a whole animal. They may confuse closing a wound with rebuilding a limb, or mistake early research for a proven treatment.
How to Assess It
- Exit ticket: Sea stars can regrow arms. What might doctors learn from this, and why can’t we promise people new arms? Cite one fact from today’s reading.

Ways to Teach It
Give pairs clay and photos of regrowing sea star arms; have them model the missing tissue and label skin, nerves, and muscle.
Ask students to write: What evidence would researchers need before testing a sea star regeneration finding as a human treatment?
Give teams claim cards about sea star arms, human wound healing, and human limb regrowth; sort each into shown or not shown.
Print the headline 'Sea Stars Will Help Humans Regrow Arms'; have students rewrite it to state a possible medical use and an unproven claim.
