Many chemists do research and create new things. Some chemists watch what happens when they mix two or more chemicals together. They explain what they might see, smell, or feel. From their research, they can create new products. Chemists can also improve products we already have and show us new ways to use them.
Chemists also work in factories.
They tell plant workers which ingredients to use to make a chemical. They also tell the workers how long to mix chemicals, and how hot or cold the mixture should be. They watch the whole process to make sure that they get the right product at the end. Chemists test samples to make sure they meet industry and government rules. Chemists also record and report on test results.
