Ocean Science


Sand/Water Table: For an ocean unit, or just for fun, purchase a bag of shark teeth from Ben Franklin, bury them in the sand table, & let students sift sand to find them. (On a recent vacation, I found real shark teeth fossils by sifting sand in Florida.)


Have available different types and sizes of shells and a magnifying glass. Encourage child to look closely at shells, smell then, listen to them…The shells could later be used for sorting or matching.


Marine Water Table:

In the water table place different marine animals. Let the children explore each animal, talking about its’ name and the sound it makes.


Natural Science or a specific habitat study: The Habitat Box

Use a small flat box, about the size of a shirt box is ideal. Visit on your own the habitat that you will be studying and pick of samples of things the children might expect to see. Example: Beach habitat – sand, small shells, smooth stones, kelp,


Science: salt water vs. fresh

First have a sample or both salt and tap water. Have the children smell and taste a little of each. Have them try floating experiments on each kind to see if there is any difference. Then fill an ice cube tray half with fresh water and half with salt. Put it in the freezer and check periodically to see what happens! Talk about what is different about the smell and taste, and what might make salt water take so long to freeze.


Sea Water:

Even if you do not live by an ocean, you can still show your class that there is LOTS of salt in sea water. In a large, see thru pitcher

If you are lucky enough to live by an ocean, you can do this with real ocean water.
