Before you get started
What do egg codes mean?
The first number on an egg tells us how the hen was raised.
0 = Organic
1 = Free range
2 = Barn
3 = Caged
The two letters tell us in which country the egg was laid.
The final set of numbers tell us which farm raised the eggs.
Carrying out your project
Choose your questions
Here are a few question ideas to get you started.Be creative to think of your own!
Can you explain what 0, 1, 2, and 3 mean in the first part of the egg code?
Should shops support higher-welfare egg farms when possible? (For example, yes, no, unsure)
Tip: Avoid personal questions for this activity so people remain anonymous.
Make a prediction
What do you think your results will show? Some example predictions are below.
Most people will not be able to explain what 0, 1, 2, and 3 tell us in the first part of an egg code.
There will be a mixture of views, with people agreeing and disagreeing that shops should support higher-welfare egg farms.
Collect and analyse
Talk with your friends and family to collect your information.
Interviews are a great way to open up further questions and learn from each other. Make notes on any interesting points you had not previously considered.
When you have enough responses (aim for 10), bring your data together and be creative in how you communicate your results – try graphs, drawings or other visuals!
Receive your certificate
Upload a photo of your results below to receive your certificate.
Share your work to inspire others and celebrate higher-welfare hen eggs.
