    After identifying the rules, assign a specific color of Post-it® Super Sticky Note for each individual element (Orange represents C. Blue represents O. Green represents H, etc.) Then, have your students write each element on the respective colored Post-it® Super Sticky Note.

    Next, have your students affix the Post-it® Super Sticky Note containing the appropriate rule on different objects around the school or in the classroom. For instance, the water in a fish tank would be marked with a two H’s and an O. This will help them recognize the simple patterns of which basic elements are contained in all the everyday objects around them.
