Science Sunday: Shrimp
I just heard about a linky sponsored by Apologia Science, so I'm gonna link this up to Homeschool Science Show and Tell!
I’m kinda thinking I need a “grocery science” category, because as I was finishing up our science experiment for the week I realized a large majority of our science experiments come from there.
Case in point. This week we were reading about different crustaceans, and I thought excellent let’s check out the lobsters at the store.
We had a lot of fun observing the different parts and remembering why the water is cold (keeps the lobsters complacent and from needing to eat).
I asked if we could touch the lobsters, but they’re not allowed to touch except with gloves on, and I was rather expecting that answer, but figured I’d give it a shot.
That night after dinner we explored the 6 shrimp I got after looking at the lobsters. I considered getting some crab too (what a great excuse to get crab, right?), but the crab is already cut in half and doesn’t have the exoskeleton on it. Kinda takes away some of the science lesson, and thus my excuse to get crab.
We went through and looked at their swimmerets, and discussed their exoskeleton, which is tough and brittle. Then we looked at the tail, talked about it for awhile.
Jeff joined in the lesson at this point, and after having pulled the tail off one, pointed out the long thin brown thing you can see in the picture (thank goodness for zoom). That is the shrimp’s lower intestine. Then we talked about how the butcher (or someone else) had already taken the head off and removed most of the organs.
Let me tell you that was the most fascinating thing EVER to them.
Afterwards they filled out the lapbook portion about shrimp and drew pictures. Oh, and they all stole Jeff’s shrimp. Back when we were on our Christmas trip they all tried shrimp and swore they didn’t like it. On Wednesday when I only got a little they all decided they loved it and stole all of poor Jeff’s shrimp.
Here’s a few fun ideas from this past weeks link-ups:
Relentlessly Fun, Deceptively Educational has a fun way to learn about spiders (I know my boys would love this).
All Things Beautiful did an experiment with the connection between taste and smell (FYI one of my boys has those same jammies).
Learning Ideas K-8 has a fun anemometer, homemade wind speed measurer. I didn’t know you could make one at home.
And one last one:
The Learning Hypothesis gave us a link to the science behind play dough.
