We ended up with two videos worth saving in February on my memory card. I found a lot of other videos, from the evening I let the 5-year-old take my camera outside, but it was getting dark and they were quite grainy, and some were so shaky I felt queasy just watching them! Our latest budding photographer needs a few lessons before I share many of his videos.
This first one shows a science experiment we did. We’re studying Apologia’s Zoology 1 book this year, about flying creatures, and they suggested an experiment to show how lift makes flight possible. Air going over a bird’s wing moves faster than the air under the wing, because the top of the wing is curved. That causes less air pressure above the wing than below it, which causes the wing to be pushed up. To demonstrate this, we cut a drinking straw so it would come just above the top of the water in a cup, then blew across the top of the cup through another straw. Because the air pressure directly above the straw was less than over the water in the cup (because it was moving faster), water blew out of the straw!
This second video is from one evening when Gayle coached the little boys and then brought them to the kitchen to sing “Read Your Bible, Pray every day” for us.
