In the middle of my Unit Plan planning, snowstorms and the general crisis mode of being in two Dr. Smirnova classes, I created a science fair project.
I can say in all faith and honesty that the science fair took its place on the back burner for me. I was focused on the anxiety of the Unit Plan, the added craziness of snow days and the absolute worst I had for the semester, which is that I would have to teach the two Unit Plans (one for Methods Social Studies and one for Methods Science) back to back.
So, given all that was going on, I can't believe I even completed the science project, yet somehow I pulled one together.
I ended up exploring buoyancy, and I did that by placing an orange in a vase with the skin peeled off, and another orange with the skin still on.
I made a quick hypothesis, that the peeled orange would float, since it was smaller. But then I wondered if the orange would float or if the water would inch up through the orange itself through the slices. I had to go forward and let the oranges hold their own water, so to speak.
I had two large vases and filled the vases with the same amount of water, 1 1/2 cups.
The peeled orange sank immediately, for all of my 5 trials. The unpeeled orange did not sink, which was a surprise.
When I dug up some information as to why the oranges floated with their skin unpeeled.
The reason was due to buoyancy. The skin acts as a floatation device and evenly dispels the water around the orange. So while I had thought that the lack of skin would make the orange lighter and therefore would float, I had started the correct thinking that the water would creep through the crevices of the orange slices and weigh it down.
I enjoyed the experiment, although I do wish I had spent more time on the project too. I learned a surprising fact, forced myself to think creatively when I really wanted to panic instead and found a new project to incorporate into my classroom.
