2020/21 Lesson 9: The Ocean

 The Ocean is a fascinating place! Did you know that oceans cover over 70% of the earth? Wow! There are 5 oceans on earth: Pacific, Atlantic, Indian, Arctic, and the Southern. Oceans provide 50% of the oxygen on earth, 97% of the water on earth, and provides over 270 billion dollars to the United States. The ocean is used for transportation, recreation, and is home to over one million species of animals. 

We looked at pictures and videos of many sea creatures. Sharks are always the most popular answer when asked what creatures live in the ocean. So, we had to spend a little more time discussing sharks!

Mark Rober videos are always a hit! Watch his shark blood videos to see if sharks are attracted to blood from a mile away. Click on this link: Can sharks smell blood?

We also discussed the zones of the ocean. We learned that most ocean life live in the Sunlight Zone. 

We had fun looking through microscopes to see objects from the ocean including: fish scales, sand, plankton eggs, and a feather (not from the ocean). 

 We looked at sea shells, coral, and sponges from the Atlantic Ocean. 

Finally, we cracked open an oyster and saw the pearl that was inside!
