Our latest inquiry has been about the beach and the ocean! While we were wondering and thinking about the Earth, many of our students gravitated towards places that were always hot. We loved finding Mexico on our globe to see how close the Equator it was. Miss Campbell, Ms. Conti and myself quickly realized our students were beginning to shift their thinking to the ocean and the beach. We began our latest inquiry by adding some new books to our reading corner about water and ocean creatures. S.Z. read about starfish in one book and in the interesting facts section at the back learned that starfish can grow back their arms! He shared this fact with our class and together we questioned: "I wonder how starfish grow back their points when one comes off?" We have a lot of theories! Take a look below to see some of our thinking!
V.T. I think there is magic dust itself.
S.Z. I think there is little guys inside their hole.

J.L. I think the starfish bones pushes out.
S.M. I think a star fish has 100 arms.
E.Rjk - I think it has another arm in the middle.
A.M. - I think starfish grow like people.
E.Z. - I think inside his body has another arm.
M.S. I Think a bone grows back in.
J.Y. - I think it is becuase the water surrounds it.
E.R.(sk/1) I think it has extra blood.
I.L. I think the starfish drinks water.
D.M. - I think there is something inside of them.
M.O. I think starfish drink water to regenerate.
E.R. (sk) - I think starfish have 100 arms in their body.
A.K.jk - I think when starfish skin grows back the arm grows back.
K.H. I think it uses tape.
U.L. - I think the starfish finds a seed.
E.W. I think it sucks water in and makes an arm.

E.B. - I think the sun gives it energy.
S.S. - I think the starfish arms will grow small to big.
A.M. - I think starfish grow like people.
S.B. - I think it needs water to put more energy on it.
J.M.X. - I think his friend gives his arm back.
T.C. - I think it has extra bones in the body.
L.H. I think it can grow underwater.
H.H. I think he eats his arm.
Thank you Mrs. Smith and E.R.(jk) family for letting us use your sea stars at our wonder table! We have enjoyed touching their bumpy surface and looking at their hundreds of tube like feet, which help them move slowly along the ocean floor.
We have learned that starfish lose their limbs for all kinds of reasons! Fishing is one cause of sea stars losing their arms. While we were learning about starfish we also found out that sea stars can release one of their arms if there is a predator trying to eat them!
After watching this video, looking at books and talking about starfish. We learned so much about them! Here are some things that we know:
- It takes one year for a starfish to grow back their arm.
- Starfish have special cells in their body that help them regrow their arms.
- Starfish can be prickly (EB)
- Some starfish are nocturnal. (PZ)
- Starfish are also called sea stars.
- Some have spikes on them. (ER)
- Starfish don't have blood. (DV)
- There are lots of different kinds of starfish. They all look different. (JY)
- Some live in shallow and some live in deep waters. (ZL)
- The biggest starfish lives in the Pacific Ocean. (JMX)
- When starfish lose an arm they can grow back another one. (SZ)
- Some can be different colours and sizes. They are unique. (VT)
