What You'll Need

Let's get your Marshmallow Detective mission ready! This experiment is essentially the same as our Puppy vs. Imposter exercise, but we want to teach kids that - AI is only as samrt as the data we give it. If a machine is trained with biased info, it will produce wrong answers.

We can use different types of candies—like colorful rock candies in two separate cups—to show how the computer learns to tell them apart. So you can start your Audio Project and Post Project from there.

1. Access to a computer or tablet with a webcam.

2. Two different types of colorful candies (like marshmallows and rock candies) placed in separate cups.

3. Access to Teachable Machine.

Can kids learn machine learning without coding?

Tools like Google Teachable Machine allow kids to explore machine learning through "no-code" experiments. By using a webcam to train an image recognition model, children learn the logic of how AI identifies patterns without needing to write a single line of code.

Dive In

The process is incredibly intuitive, but if you want to guide your little scientist through it step-by-step, here is your official mission plan:

1. Go to Teachable Machine and start a new Image Project.

2. Defining the Suspects: Rename Class 1 to Team Marshmallow and Class 2 to Team Rock Candy.

3. Gathering Intelligence: Use your webcam to take 30 or more photos of the marshmallows. Move the cup around, tilt it, and show the computer what they look like from different angles.

4. Scanning the Imposters: Switch to the second cup. Take 30 or more photos of the rock candies in the Team Rock Candy section.

5. The Brain Swap: Click Train Model. This is when the computer learns to distinguish between the soft, white shapes of the marshmallows and the jagged, colorful edges of the rock candies.
6. The Final Interrogation: Hold up on of the candies or even mix of both. Does the computer correctly identify which team is which?

Now that we have the steps down, how should we explain the science behind this to the kids? We could choose one of these areas to focus on:

The Power of Data and Manipulation : Don't forget to take AI, and also media answers with a grain of salt. They can be wrong! Machines don't think for themselves - if you train a model to call a candy a cat, it will folow your lead without questions.
Pattern Recognition: Discussing how the computer looks for shapes and colors rather than "tasting" the candy.
Making Mistakes: Exploring what happens if we show the computer a candy that is halfway between a marshmallow and a rock candy.

✏️. Always use your critical thinking skills when looking at AI or media. They aren't perfect, and they often follow a specific "script" they were given. A machine's output is only as good as its training—if you train it to think candy is a cat, that’s exactly what it will report.
