Science Sunday: Shrimp



A few months ago I shared how we dissected a shrimp, however the shrimp we got from our grocery store was already beheaded.  We got ones with shells on, so they saw the tails and legs and such stuff, but they really wanted to know what the head looked like, up close and personal.


I joked about going out for sushi and making my brother order fried shrimp heads again (he did it on a dare once, it was AWESOME), but Jeff didn’t think that was the best plan, for many perfectly valid reasons.




Then, when we were in Virginia we ate at this perfectly horrible Chinese/Japanese buffet.


Horrible, they messed up jello so badly I couldn’t eat it.


But, they had shrimp with their heads on.  So, right there in the restaurant we had a science lesson.


First thing we noticed is how HUGE the eyes are.  I personally think they’re kind of freaky.




Next we noticed the length of the antennae.  They’re about as long as the shrimp itself.


This required a lot of playing and fiddling around to see how much it could be moved.



And then some general exploration of how it moves and the different parts of it.


Of course eventually it was eaten.


I guess that day we played with our food.


Let’s see what others did this week:

Finding the Teachable Moments shared about their Fire Safety week, a great pre-school/early elementary unit (you have to see what her husband brought home from work!).


Homeschool Mo did a couple of things this week, but I really loved her illustration for the earth circling the sun using a pie pan.

Science Sunday on Saturday: Louisiana Crawdads

Science Sunday


So do you say Crayfish, crawfish, or crawdaddy?


We read one of the Johnette Downing books I referred to earlier, “Why the Crawfish Lives in the Mud?”  You like how Aunt Tara got suckered into reading to them when visiting?

Afterwards we took some time to read through it again more slowly and we talked about what was true in the book (where crawdads live, what the eat) and what wasn’t true (the animals talking, crawfish being a trickster).


Sigh, and sigh again, I have no pictures of them doing this.  None, my computer ate them, bad computer.


My follow on was going to be to study one from the grocery store, like we did shrimp, but timing never worked out right.  Maybe we’ll check it out again someday and do that.


Have you ever looked for truth in fiction books?



A couple of weeks ago Mama to 4 Blessings linked drawing out a primeval reptile’s head.  I love the visual of that, and we forgot to do that when we covered that chapter.

I loved these snakes over at Learning Hypothisis to demonstrate gravity.

Over at All Things Beautiful she found these great worksheets on whales and a few other fun things on the course website for Apologia Swimming Creatures.  I keep forgetting to check these out.

Books 4 Learning reviewed a cute picture book about insects this week.  I’ve pinned it for next time we get to Flying Creatures.

Science Sunday: frogs

Science Sunday
I thought it’d be good to review our study of frogs.

We read this book and also reread the section on frogs and toads in our science book.

Afterwards we talked about the differences between frogs and toads.


Earlier I had gone over to my swimming creatures pinboard and found this idea by Relentlessly Fun, Deceptively Educational (printable included there).  She had linked it up to Science Sunday right after we’d studied frogs and toads, so I didn’t do it then, but saved it as a review activity for a day when the kids wanted a craft and I wasn’t up for a big craft.

So, they happily colored and talked to me about the differences.

Frogs have longer legs for hopping, and have smoother skin (generally speaking).

Toads have shorter legs and have bumpier skin.
We also looked at the difference between frogs and toads for more information.

By the way my boys decided their frogs were poisonous, so they colored them bright colors to warn predators they were poisonous.

It was even more impressive when we found a toad in a neighbor’s front yard and they correctly identified it, and then spent 10 minutes chasing the poor thing around the yard.

It’s so much fun when they show off what they’ve remembered from earlier lessons.

I’m also going to try and start showing off some posts that were linked up in previous weeks.  So, here’s a few that stood out to me:

Changed by the Maker showed off her artificial gravity experiment.

 And Next Gen Homeschooler made plastic using milk as part of her Letter M studies.  I know it is bad grammar to start off a sentence with a conjunction, but I’m lazy.

That’s it for this week, I can’t wait to see what ya’ll have done!

Science Sunday: North Carolina: tar and water proofing

Science Sunday

North Carolina is nicknamed the “Tar Heel state,” I read a couple of reasons for this but it all boiled down to there is a lot of tar there.  Tar was originally used for water-proofing boats.  I don’t have any boats to try water-proofing with, but I have paper.

North Carolina Tar Heel State


First, I smeared the various things that have been used for water-proofing onto the papers and let that soak in for a while (I gave it about 30 minutes).




Then each of the kids got to take turns putting water with an eye dropper onto the various pieces of paper.


As you can see it was very exciting results.  I was even surprised by some of them.


I wasn’t too surprised the butter and oil repelled water, those I expected because they were used in the colonial time periods to make cheap semi-translucent window coverings that were somewhat waterproof.  The paint also didn’t surprise me because we used paint to seal wood against water for our houses.  The rubber glue and the Elmer’s glue did surprise me.  Elmer’s because it is water-soluble, and the rubber cement because I only put on a very thin layer.


Of course the plain old paper immediately soaked up the water.  I want to repeat the experiment and keep checking back to see if it has soaked in, that was my original plan, but some of the papers were thrown away right away.


How about you guys?  Anything fun this week?  Any surprising new discoveries?

Science Sunday: Ben Franklin

Science Sunday
What study of Pennsylvania would be complete without something about Ben Franklin inventor extroidanairre (bother, apparently I’m so far off on the spelling of this word spell check doesn’t even have a clue, anyone know what I did wrong, or did I invent a word?)?

Okay, admittedly there are many other famous people in Pennsylvania, but this is one of the people our library had a book on that was checked in.  After a couple of tries.

There’s one I’m gonna want to get about actually doing some of his experiments, but I digress. Widgets


As I read the book, the kids found the corresponding invention and would either draw or write the corresponding invention that Ben Franklin had made (the page was cut with flaps on the lines between each picture).

Some of the pictures are less self explanatory than others (the second from the bottom is a heater), but overall the kids had no real problem with completing it as I read it.

Now, can I interpret what the pictures are my kids drew?  Not really.

But, it was still fun.
