Great White Shark: The Ocean's Ultimate Predator

After listening to "Great White Shark: The Ocean's Ultimate Predator," you'll become a shark super-sensor yourself! We'll investigate just how a shark uses its amazing senses to find its way around the ocean, just like the great white.

The Big Question

How do sharks "see" and "hear" their world without ears and eyes like ours?

What You'll Need

• A small bowl of water
• Food coloring
• A dropper or spoon
• A dark-colored piece of paper or fabric

Mission Steps

1. Dark Water. Fill your bowl with water and add a few drops of food coloring. Swirl it gently to make the water dark and murky, like the ocean.
2. Sense of Smell. Hold the colored paper or fabric over the bowl and let it hang down into the water. Can you still smell it? Sharks have an incredible sense of smell.
3. Feeling Vibrations. Gently tap the side of the bowl. Can you feel the tiny vibrations travel through the water? Sharks can feel these movements from far away.
4. Electro Sense. Imagine you have tiny dots all over your face. Sharks have special pores called ampullae of Lorenzini that can sense the tiny electrical fields from other living things. Try closing your eyes and imagining feeling tiny electric sparks around you.

Talk About It

• What did you notice about trying to smell the paper when it was in dark water?
• How is feeling vibrations in water similar to or different from how we hear sounds?
• How do you think a shark's senses help it survive in the ocean?

Take It Further

For older rangers, research sharks' lateral lines. This is a special sensory organ that runs along a shark's body and detects movement and pressure changes in the water, helping them navigate and hunt in murky conditions.

FAQ
