Mystery Science really covered everything in this fun and educational activity. The interesting subject of water combined with some sneak attack math. This is made out like a game so kids don't even notice that their learning. You will need the print outs for this one and it is best done in groups or at least with more than one student as they will need to bounce ideas off each other and help each other with the math. Great activity that I think would work at home or the classroom. Also if you don't have stickers, you can use little cut up pieces of paper.
