Finned, Floating, and Fabulous: A Shark Science Activity
The Discovery Channel’s Shark Week might be officially over, but if you haven’t had your fill, you can try our Shark Science Activity for kids. This activity is a Shark Week recap that reinforces one of the more surprising lessons we learned about shark anatomy and physics.
Why Don’t Sharks Sink?
The great white shark can grow up to twenty feet in length and weigh over two tons. That’s more than the weight of a car! Like cars, sharks are denser and heavier than water. But cars sink in the water, so what keeps sharks from sinking?
It’s not the fins, and it’s not just the fact that sharks swim constantly. If you want to find out how sharks keep their balance in the water, start our Shark Science Activity by clicking on the image below.
Strange Shark Facts
Discover more unusual tidbits about sharks below, which were all taken from the Discovery Channel’s “Shark Facts” page.
- Sharks breathe by processing oxygen from the water that enters their mouths.
- Great white sharks protect their eyes during attacks by rolling them back into their heads.
- Shark pregnancies can last from five months to up to two years.
- It’s not the scent of blood that sharks “smell.” Shark noses can sense electricity, so they smell the change in the water when blood changes its conductivity.
- You’re more likely to be bitten by a person than by a shark.
- Tiger sharks have been found with whole tires, license plates, and more in their stomachs.
- Shark diets are affected by the moon phases because the tides bring them closer to the shore.
- Great white sharks take a single bite to decide whether they want to eat their potential meal or not.
