Chemistry experiments and algebra problems sometimes ask students to create percent mixtures or to change a mixture into a stronger or weaker solution by adding more of an ingredient. Students often have difficulty isolating the key concepts involved in this sort of problem. This investigation introduces the notion of changing percent mixtures through a fun class day that ends with a yummy treat. This activity is perfect for a middle school algebra class or any high school math class. Students set up and solve equations to solve mixture problems.
