Students love doing experiments. However, they often tend to waste a lot of reagents. A good way of teaching them to be less wasteful is through microscale chemistry. Here is an example of the worksheet I designed to teach my students to be more conscious of the amounts of chemicals they are using:
In this experiment students conduct 5 precipitation reactions and use 2-3 drops of each reagent. The worksheet is laminated and a paper towel is used to clean up afterwards. Once prepared it will last a long time.
