Hi there! Let's talk about things in a safe and helpful way. Sometimes, people talk about substances like medicine or other materials being divided into smaller parts. For example, if you have something that weighs one gram, you can split it into many little parts, like tiny lines. How many little parts you can make depends on how big you want each part to be!
It's very important to know that some substances, like drugs, can be very dangerous and hurt people. That's why grown-ups and teachers tell us to stay away from those things and only use medicines approved by doctors.
If you have questions about science, medicine, or anything else, always ask someone you trust, like a parent or teacher. They want to help you learn safely!
