    A Chemistry Scavenger Hunt 

    Kids, tell your teacher that you would like your class to do a chemistry scavenger hunt! These are really popular assignments where students are asked to identify or bring in items that fit a description. Examples of scavenger hunt items are below. Many of these topics have been tackled in our previous 150+ columns. A partial list of possible “answers” to 5 items is also provided – you can find more at the website below.

    Please note:  All chemicals and experiments can entail an element of risk, and no experiments should be performed without proper adult supervision.

    First, start with the clues. Find:

    1. An element
    2. A heterogeneous mixture
    3. A homogenous mixture
    4. A gas-liquid solution
    5. A malleable substance
    6. A solid-liquid solution
    7. A substance that has a volume of 1 cm3
    8. An edible example of a physical change
    9. An edible example of a chemical change
    10. A pure compound containing ionic bonds
    11. A pure compound with covalent bonds
    12. A mixture that can be separated by filtration
    13. A substance with a density less than 1g/mL
    14. A substance with a density more than one
    15. An acid
    16. A metal
    17. A non-metal
    18. Immiscible liquids
    19. A base with a pH greater than 9
