Ocean experiment
By Lori

How about a salt water experiment? I used to do an experiment where we watched 2 dishes of water (one "fresh" water and one "salt" water) over several days. As the water evaporates the students can see that the fresh water
just disappears and of course the salt water leaves behind salt. You could have them taste the salt water too. Just dip a q-tip into the solution and then place it on their tongue. I have also put "fresh" water and "salt" water into two plastic see through containers. The students can then see how you can see through the fresh water and the salt water is kind of foggy. Is this what

you are looking for?

How about this: After reading many books on oceans and ocean animals I do an activity so that the students understand just how big ocean animals can be. I found the lengths of different animals; killer whale, dolphin, hammerhead shark, etc. and measured string to that length. The students can stretch the string out and see just how large the animals are. You will need to do this in a gym or on the playground. They can never get over how BIG the animals are.

Hope this helps! Good luck.
