Science Sunday: shells, really the last one

Science Sunday

I just heard about a linky sponsored by Apologia Science, so I’m gonna link this up to Homeschool Science Show and Tell!

This activity comes from my Swimming Creatures pinterest board.  Over at the Crafty Classroom she put together a great sea shell printable identifying them to the best of her ability.  I tried to look for some others to add to my collection, but didn’t find any.  Does anybody know of any other shell printables?
We went through our shells and slowly sorted them into the different types.  We ran into several which didn’t quite fit the pictures we had, so at that point it got into our best guess.

This is a great way to talk about classification and the minor differences you can find in things.
What makes this one a whelk and this one a conch shell?

Of course eventually it turned into a boys versus girls thing.  That didn’t go over quite so well because both boys would pick the same type of shell and say, “This is ____________ (fill in the blank of a child’s name they know) and he’s part of the boy group.  There’s more boys than girls.”

Yeah, and that would be when I ended that activity.

However, the concept is still sound, and they are still talking about it a few weeks later, so I guess over all it was a win.

Fantastic Five did a fun activity making their own constellations, she based it off a similar constellation post from Relentlessly Fun, Deceptively Educational.  It was fun to see someone doing what someone else had linked up to Science Sunday!

Alex Nguyen Portraits had a fun experiment of How many pieces of styrofoam can fit in the can?  You have to go there to see the fun twist she had in it.

So, I guess in the end it was a mixed result.  Sigh………


Science Sunday: shell sorting

Science Sunday

I was hoping to have some amazing pictures this week of the triops that had hatched…….  However, we’re into the start of the time when they MIGHT hatch, provided I never got the water too hot.  This might not have been the ideal experiment for us to try.


Instead, I’ll start telling you about the next lesson we’re learning: SHELLS!


After reading what animals live in shells and how there are many types, we first read about bivalves, so today’s lesson is on bivalves.




Setup: Each kid had a pile of shells and a few non-shell items and a piece of felt.


Goal: To separate out the bivalve shells from the non-bivalve shells and to remove the non-shell items from the grouping.


Pretty simple, but fun right?


Next we sorted through the bivalves and looked for ones that were broken or had small holes in them.


Question: How did this happen?  What is the difference between a broken shell and a shell that has a hole in them?


Shell with small hole drilled in it- that was eaten by a sea snail that drilled the hole and sucked out the mussel in the shell.


Broken shell- it was broken by a land animal most likely.  Sea otters will lay on their backs and crush clams with rocks.  Sea gulls will drop clams onto rocky shores to shatter the shell to eat the clam inside.


Afterwards I gave them some time to freely explore the shells and look at them some more.


They were given some ocean life flashcards, a book about sea shells with pictures of them to identify them, and a magnifying glass (sadly the store I got mine from seems to of discontinued it).


Oh, and just so I have a chance of knowing who is who later on, Superman is wearing the Batman lego shirt and has the blue felt.  I’m basing this mainly on the blue felt because blue is his favorite color.

Snacks and Stories had a fun idea of comparing blowing different substances with and without straws and what the results are.

Relentlessly Fun, Deceptively Educational made a fun yarn bird’s nest.


Child’s Play Music has an interesting idea for making music with water and common household items and explains some of the science behind it.

Creekside Learning linked up a fun series of ideas from their astronomy unit (aside from my favorite oreo phases of the moon idea) she also used them with the calendar to mark when it happened.


Learning Hypothesis had a fun experiment involving forces, pushing/pulling with balls.


Anyone have any other fun ideas about shells?  I have a few more things we’re going to be doing and I’m looking forward to more explorations.

Science Sunday: Water currents

Science Sunday

We’ve started our next science book, Exploring Creation with Zoology 2: Swimming Creatures of the Fifth Day.  Or as my kid call it “The Ocean science book.”


The first chapter is basically setting up what the ocean is like.  So, we first read about plankton, and many other things, and then we got to currents, and I remembered All Things Beautiful having a wonderful experiment about currents and all sorts of things (she has older kids, so went into a lot more detail).



So, we happily set up our potential currents and our oh so official land masses.


For full explanation of set up and science head over to All Things Beautiful, but here’s my kid’s observations:


And after talking about that for a little while we did the next step.



Blowing on it, to simulate wind and other surface events that affect the oceans.  It was hilarious seeing them blow it all over and their amazement at the colors mixing.  Then we talked about how someone in the United States could drop trash in the ocean and how that could affect someone in Africa.


In our science book there was a hilarious example about a boat carrying Nike shoes that sunk in Atlantic Ocean Gyre.  Scientists were rubbing their hands in glee as they theorized what would happen to the shoes, and they got to watch as the shoes moved exactly where they predicted.

Of course they didn’t really say how it got cleaned up, but it was a great example of how something that is dropped in one place can


Quick reminder to those of you linking up:


1.  Don’t forget to link to your exact post (I read most of the posts on the Friday after so I can catch all the posts added in for the week).  Also, I go back from time to time as I remember someone did ________________ that was super cool.  It’s much easier to do if you’ve linked to your exact post.


2.  Please remember to put a link back to Science Sunday.  Either put in the button, or just make a word hyper link.
