Snow-Holes and the Scientific Method
I was walking my dog, Buddy, in knee-deep snow yesterday. We walk (I walk, he runs) at a nearby farm. As we walked, I noticed numerous small holes in the snow. Upon closer examination, I found that each such hole in the snow had a small object at the bottom of it.
Figure 2A and B show a seedpod and a leaf that were blown from some nearby trees (you can see them on the left in the first insert) and had sunk into the snow. Interested in how they got so deep in the snow, I dug out the seedpod and the leaf and ran a quick experiment. Dropping them back down onto the surface of the snow, I watched them settle on top of the snow without sinking in. I concluded that whatever caused them to sink into the snow must take time.
