In this experiment, the 3rd graders discovered that volume and capacity are not one in the same. I explained to the class how upset that I was when I opened my can of seltzer to find it was not full! However, the students discovered that when companies print “355 mL” on the can, that is the VOLUME, or amount of liquid in the can, not its capacity, or the amount of liquid it would take to fill up the can.
Here are a few pictures of our kiddos hard at work! I was so proud to see how well they took turns and shared responsibility in this activity 🙂
