Fun End of Year Inquiry Science Activity

Let me guess- you’re already thinking about the end of the school year.  You’re tired, but you’d like one more meaningful activity.   Maybe something that could even give a nice spark to the end of the school year.  Is that how you feel? If so, you should consider the classic “Measure Colored Liquid” activity (it’s also commonly called the “Measuring Volume Lab”).

Essentially, here’s how the lab goes- students get into groups, and each group gets 6 test tubes and 3 beakers of colored water.  The instructions tell them to put certain volumes of certain colors into certain test tubes, and to also pour between the test tubes along the way. If they follow the directions perfectly, they’ll end up with a beautiful rainbow across their test tubes, all with the exact same amount of liquid!
