Kavi Tests a Beak

Kavi looks at birds and sees that every beak is a different shape — a hooked one, a thin one, a wide one. "Is a beak's shape an adaptation that suits the food it must handle?" hoots Kavi. To find out the fair way, Kavi uses kitchen tools as pretend beaks and times how many seeds each one picks up. "I change just ONE thing — the beak's shape — and keep everything else the SAME: same seeds, same number, same time, same bowl. The one thing I change is my variable. Then I count, and read the pattern in my data — just like a real scientist!"

What your child will learn

1A beak is a tool shaped for its foodA bird's beak is an adaptation — it is shaped to suit the food the bird must handle. Tap each beak to see the job it is built for!
2A leaf's shape and covering suit its habitatLeaves are adapted the same way. Tap each leaf to hear how its shape and covering suit its home.
3Which do you change, which do you keep the same?In a fair test you change ONE variable and keep every other thing the same. Try it on Kavi's beak investigation.
4Read the pattern in the dataWe used the same seeds, the same number and the same time, and changed only the beak's shape. Then we counted the seeds each beak picked up. Read the bars from left to right — the wider the beak, the more seeds it scooped. That rising trend is the pattern in our data.

A peek inside

I want to find out if a BEAK'S SHAPE changes how many seeds it can pick up. What is the ONE thing I should change?
A fair test changes only the one thing I am testing. Here I am testing the beak's shape, so I change the beak shape and keep everything else — the seeds, the number, the time, the bowl — the same.

Try this at home: In a fair test, how many things should you change at one time?
