Sara likes to go to the lab with her dad. Her dad is a doctor who helps sick people. The lab is a big room with many machines and bottles. Sara likes to look at the machines and bottles, but she cannot touch them. They are not toys.
One day, Sara sees a white dog in the lab. The dog is very friendly and wags its tail. Sara likes dogs. She asks her dad, "Can I pet the dog, please?"
Her dad says, "Yes, you can, but be careful. The dog is not a normal dog. He is a special dog. He has a chip in his ear that helps us learn about his brain."
Sara is curious. She asks, "What is a chip? What is a brain?"
Her dad says, "A chip is a small thing that can talk to the machines. A brain is a part of your head that helps you think and feel. The dog has a chip in his ear that tells us what he thinks and feels. We want to know how he learns and remembers things."
Sara thinks that is very interesting. She pets the dog and says, "Hello, dog. What is your name?"
The dog looks at her and barks. The machine next to him makes a noise and shows some words on a screen. The words say, "Hello, Sara. My name is Max. I am happy to meet you."
Sara is amazed. She says, "Wow, you can talk to the machine! That is so cool!"
Her dad smiles and says, "Yes, he can. He is a very smart dog. He is also very nice. Do you want to play with him?"
Sara nods and says, "Yes, I do. Can we play fetch?"
Her dad says, "Sure, we can. But only in this room. And don't throw the ball too hard. We don't want to hurt his chip."
Sara agrees and picks up a small ball. She throws it gently and says, "Go, Max, go!"
Max runs after the ball and brings it back to her. He wags his tail and barks. The machine says, "Good girl, Sara. You are fun. I like you."
Sara laughs and hugs Max. She says, "I like you too, Max. You are the best dog ever."
