Online Science Class for Preschoolers: What is in the Ocean?

WEEK 4: Oceans

Day 3: What is in the Ocean?
Overview: You could spend many hours on many days studying what is in the ocean.  This lesson lets your child learn look at patterns, discuss size, and think about diet.  The lesson appeals to the Verbal-Linguistic, Logical, Visual-Spatial, Bodily-Kinesthetic, Naturalist, and Intrapersonal intelligences.

Science Time!
  • What's under the ocean?  Let's climb in our submarine and travel underwater.  Take turns with your child pointing out things you "see."  Look at and discuss pictures of animals and plants that you can find in the ocean. 
  • The ocean is full of many different kinds of animals that have shells.  What kinds of patterns do you see on these shells?  Give your child some time with the magnifying glass to study the shells.  Encourage her to draw pictures of them in her Science Notebook.
  • The ocean has lots of seaweed in it.  Many animals eat seaweed, including endangered sea turtles.  Have you ever tasted seaweed?  It's okay for people to eat.  Let's try some!  (Carrageenen, a seaweed extract, is used in many products--including breads and desserts--as a thickener.)
  • The biggest animal in the ocean is a whale.  Whales can be 100 feet long! How long is that?  Let's find out.  Unwind the 100 foot long piece of yarn with your child.  How many times could you fit inside this whale?  Let's find out!
  • What would you eat if you were that big?  Most whales eat plants and animals smaller than a graham cracker!  Can you imagine how much food they would have to eat to get full?
  • Science Notebooks:  Draw or write about what we did today.
