Bird Beak Challenge
Essy
Mission Briefing.
Essy was exploring a natural history museum when she noticed something strange.
Some birds had long, thin beaks.
Others had short, powerful beaks.
Some looked like giant spoons.
“Why would birds need so many different beak shapes?” wondered Essy.
Could a pelican survive with a hummingbird’s beak?
Could a finch crack seeds with a spoon-shaped beak?
To investigate, Essy created a bird feeding challenge.
Can you discover which beak design collects the most food?

Mission Equipment
• Dried beans
• Plate
• Tweezers
• Clothespin
• Spoon
• Small scoop
• Timer
Let’s Investigate
1
Create the Feeding Ground
Spread the beans across a tray.
Place an empty plate nearby. This will be your bird’s nest.
3
The 30-Second Feeding Frenzy
Set the timer for 30 seconds.
Use your beak to collect as many beans as possible.
Move them to the plate before time runs out.
5
Test Another Beak
Choose a different beak.
Keep the beans, timer and feeding area the same.
Scientists call this a fair test.
7
Compare the Results
Which beak was most successful?
Which was least successful?
Did the results match your prediction?
2
Choose Your First Beak
Select one of your bird beaks.
Will it be the tweezers?
The spoon?
The clothespin?
Make a prediction before you start.
4
Count Your Catch
How many beans did your bird collect?
Record your result.
Return all beans to the tray before the next test.
6
Complete Your Investigation
Test all remaining beaks.
Record each result.
Which beak collected the most food?

Have you ever tried eating soup with a fork?
Or picking up rice using your fingers?
Some tools work better for certain jobs.
Birds face the same challenge.
Different foods require different beak shapes.
Could a bird survive if it had the wrong beak for its food?
Think back to your 30-second feeding frenzy with each beak.
Which beak collected the most beans? Were you surprised
What made that beak better at the job than the others?
Which beak was the hardest to use — and why do you think that is?
The best tool depends on the job — that's what adaptations are all about.
A surgeon uses tweezers, not a spoon. A chef uses tongs, not chopsticks. Why does the tool have to match the task?
A duck has a flat, wide beak. What kind of food do you think it eats?
If the environment changed and seeds disappeared — what would happen to seed-cracking birds over time?

Think Like a Scientist
Scientists don't just do ONE experiment; they change one part of the experiment (independent variable) and then see how it affects another part of the experiment
(dependent variable)
Change ONE variable and test again.
What happens if you change the food?
What happens if the food is spread further apart?
🧪 Try it! Change ONE thing and test again. What did you discover?

The Science Behind It
Different Birds, Different Beaks
Birds eat different foods.
Some eat seeds.
Some catch insects.
Others catch fish or drink nectar from flowers.
That’s why birds have different beak shapes.
Built For The Job
A finch has a strong beak for cracking seeds.
A hummingbird has a long beak for reaching nectar.
A pelican has a scoop-shaped beak for catching fish.
Different beaks help birds collect different types of food.
Scientists call features that help animals survive adaptations.
What Did Your Results Show?
Which beak collected the most beans?
Did one beak work better than the others?
Would the same beak still be best if the food changed?
Scientists investigate questions like these when they study animal adaptations.

Think Like a Wildlife Scientist
Scientists rarely ask:
“Which beak is best?”
Instead, they ask:
“Best for what?”
A beak that is perfect for picking up beans might not work well for seeds, insects or fish.
Real scientists test animals in different environments to discover how adaptations help them survive.

READY TO TEACH THIS
TOMORROW?
Running the experiment is easy; however, teaching it well is another challenge.
Teachers often ask:
How do I adapt this for Stages 1,2 or 3?
What do I do with fast finishers?
What misconceptions will they have?
How do I structure this for a full class?
What syllabus outcomes does it cover?
What do I say when they ask WHY?
