Swimming Creatures Lesson 13: Other Interesting Aquatic Animals

As we wrapped up our study of aquatic creatures, we learned about sponges, sea squirts, leaches, bristle worms, flatworms, and microscopic creatures like rotifers and tardigrades. We learned how scientists classify an animal as an animal and not as a plant (some of the creatures look like plants!), what sponges do for the water environment around them, what the ostia are in a sponge, what the ossculum of a sponge is, what a bristle worms bristles are used for, how leaches eat, why some flatworms look like nudibranchs, how rotifers get around and why they are called that anyways, what a water bear is and why they can be found with rotifers in many bodies of water. One very important thing we talked about is why some animals have features similar to other animals. The answer is very simple - they have the same Designer! Our experiment was to learn about the process of desalination. We learned that means to remove the salt water through the process of distillation. I have really enjoyed all of Jeanie Fulbright's books and appreciate her Charlotte Mason approach to science, her conversational style of teaching, the notebooking activities, narrations and experiments! Now that we are done with Zoology 2, and the weather is nicer, we will jump back where we left off with Zoology 1: Flying Creatures of the Fifth Day and study insects and bugs. . . AFTER we take a break!
