A chemist is like a scientist who likes to study and play with tiny things called molecules. Molecules are very small pieces that make up everything around us, like water, air, and even our bodies!
Chemists use special tools and equipment to understand how molecules work and what they like to do. They mix different molecules together to see what will happen, just like when you mix colors to make a new one! But instead of paint, they use chemicals.
Chemists also learn how to make new molecules that can be used to make things like medicine, soap, and even food! They need to be very careful and follow special rules to make sure everything is safe and works the way it should.
So, in short, chemists are people who love to play with tiny things called molecules and use their knowledge to make new things that can help people.
