DISCUSS: How are these beaks different?

Thinking Activity (Part 1)

A bird’s beak is like a tool that helps the bird eat. What kinds of tools would you use if you wanted to:

  • Crack a nut open?
  • Scoop cereal out of a bowl filled with cereal and milk?
  • Sip soda from a tall glass?
  • Catch a slippery fish?

Can you think of a bird beak that works like these tools?
If you’re stumped, advance to the next slide to see our ideas.

Thinking Activity (Part 2)

At Mystery Science, we use nutcrackers for cracking nuts. A parrot’s beak is short and strong, and it works like a nut cracker.

A spoon is good for scooping up soggy cereal. It works like a duck’s broad bill.

A straw helps you sip soda from the bottom of a tall glass, just like the hummingbird’s beak lets that bird sip the sweet juice called nectar from the bottom of a flower.

A fork can stab a slippery fish, just like the pointy beak of an egret.

In this lesson, students carry out an investigation to determine the relationship between the shape of different bird beaks and the food each bird eats. In the activity, Find the Best Beak, students experiment with long pointy beaks that are great for picking up seeds and wide flat beaks that are good for scooping. They discover that different beaks are best for different kinds of food.
