In fifth grade Wellness classes we are discussing caffeine and how it affects our bodies. We look at the definition of a drug: a substance that changes the way your mind or body works. We discuss four categories of drugs: drugs that are legal for everyone, drugs that are legal only for adults, medicines and illegal drugs. We will be studying caffeine in depth, focusing on how it affects our bodies and the effects of consuming too much caffeine. We also look at the caffeine content of commonly used drinks and snacks and discuss good choices.
