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.
