Ok, so you know how you can make those cute little ziplock baggy water cycles? Well, I thought I would take it up a notch and create mini-water cycles using the front part of the plastic packaging you find on glue stick packs and Expo packs. The picture above is misleading because it looks pretty nice, but I actually cropped out all of the shortcomings and “leakage.”
So, here’s the steps to what I attempted to do:
First, I outlined the plastic packaging on a piece of cardstock and then had the students take turns in small groups drawing the different sections of the water cycles.
Then, I laminated the card stock. I hole-punched a hole in the top of the plastic packaging. Then, I glued the plastic package under the edges with clear Elmer’s glue (not the white kind because it will milky up the water later on).
Then I “sealed” the edges with 3M’s weather sealant tape.
The students then filled the bottom “ocean” part with tinted blue water through the hole I had made in the plastic from the very beginning. We then plugged the hole with modeling clay and taped the water cycles to the window.
So far, we have had a 25% success rate of water cycles not leaking, and I still haven’t seen any condensation at the tops of the packaging :(. Oh well, you live and you learn.
Of course I asked my students about what solutions they could think of to fix the leaks. We’re supposed to be training our students to be good problem-solvers, right? That was my objective all along! 😛
Do you have a suggestion to make this project work? I would love to hear it!
Here’s one that is still retaining its water but you can still see on the cardstock where there are leaks.
