Other Interesting Aquatic Animals

Lesson 13 ("Other Interesting Aquatic Animals") is the very last lesson in Apologia's Exploring Creation with Zoology 2: Swimming Creatures of the Fifth Day and writing this post is bittersweet ... bitter because we have loved this text so much and have enjoyed it thoroughly, but sweet because it's another text under our belts and we know so much more about this amazing world that God made for us to live in.  We have truly loved this curriculum.
This lesson also allowed us to finish up our work in our Junior Zoology 2 Notebooking Journal.  It is always such an accomplished feeling to page through our completed journals.  Maggie keeps them safely in one of her desk drawers, a drawer just for her completed Apologia notebooks.  I love seeing her take pride in her hard work.
We started this last lesson reading about how scientists define animals -- basically, organisms that are multicellular, mobile consumers (as opposed to unicellular, immobile producers).  Some of the animals in this lesson appear to be plantlike, but because they fall under the "multicelluar, mobile consumers" category, they are animals.  The first one we studied in depth was sponges.  Maggie had a lot to say about sponges in her notebook.  She wrote so much, we had to attach a page.
We found a really fun video on sea sponges at https://www.youtube.com/watch?v=m8a0oNsDEx8 (below).  (I even subscribed to all of this guy's videos, I was that impressed.)
After watching, Mags filled out a video review sheet (which I make on the computer) and we attached it to her notebooking journal.
In our specimens box, we have a sea sponge.  (You can pick one up at a craft store in the painting department.)
This sponge does not contain the spicules that some species do.
Next, we did a Google image search on the common red sponge.  (Here is a good picture of one.)
I chose the common red sponge because Mags has a slide of that same species in her prepared slides her grandfather gave her.  (Thanks, Dad!)  We quickly set it up under her microscope.
Fascinating!
From there, we learned about sea squirts, water worms, bristle worms, flatworms, and microscopic water animals, like rotifers and tardigrades.  Microorganisms are so neat.  I knew Maggie would enjoy learning more about these little critters.  After our reading, we watched the "A Teeny Weeny Adventure" episode on this The Cat in the Hat Knows a Lot About That! Surprise, Little Guys! DVD.
You can watch that same episode at https://www.youtube.com/watch?v=thf4dAA2aPM (below).
We recorded all we were learning about these creatures in our journal.
It was then time to find some microorganisms for ourselves!  I snatched up these awesome plastic test tubes at Dollar Tree not too long ago (I know!  I was so stoked!  A dollar!!) and we headed to a local pond to grab some water samples.
This was the place Maggie picked to get her samples.
My little scientist!
Sample #1!
We got our second sample from a different spot.
We were ready to see what we got!
Fists full of microorganisms?  We were soon to find out!
Back home, we were thrilled to see them swimming in our samples!  When I took this picture, the frame had three microorganisms swimming in view.
You can make out some of what we were seeing in the lens in this picture.
Once some microorganisms were spotted, I had her record her observations on this worksheet I made up for times when we use our microscope.
Here is her completed sheet, which we added to her journal.
We completed the rest of the activities in her journal for this lesson ...
... before I had her write a paragraph telling of her favorite thing we learned about from Zoology 2.  I put together this sheet for her to write it on.
Her favorite lesson was the one on crustaceans (Lesson 8).  She still can't get over the hilarious mating dance of the fiddler crab!
Finally, it was time to add the last few ocean creatures to our ocean box.  Here, Mags is making a sponge.
 Daddy made her a flatworm ...
 ... and these neat tubeworms.
 They went into the ocean box with everything else and then we were able to admire our completed project.
 Once done, we moved it to a high place on a bookshelf so it's not a temptation for our naughty kitties.  I think Mags did a great job!
And so that's a wrap!  Zoology 2 has been our favorite Apologia science to study so far.  As I write this, we have just today started the Botany text, so if you are following our Apologia posts, stay with us because these posts will continue.  Happy studying!
