In a previous post, we explored gliders and paper airplanes. If you search for preschool gliders, well, you can see from the image above pretty much the only kid of glider you will discover so I am going to sift through the furniture ads and pictures of cute Australian sugar gliders to find some flying machines you and your preschooler can make.
This is a nice description of the gliders we make in Messy Fingers with a bit of good explanation at the end as to why this flies.
Essentially the two circles help to channel the air and create lift. What happens if the two circles are the same size? Does it matter which way you throw the glider - small circle or big circle first?
Egg Carton Glider
This is a really cool glider made from a foam egg carton. There is no explanation at that site as to how or why it flies the way it does. It is presented more as a craft project, but the template is great.
Is the penny necessary? What would happen if you left it out or added two pennies?
This was a very colorful and detailed explanation of how to make these gliders. Here is a better explanation of the science, but with only two colors.
Does the length of the wings matter to the helicopter? If you made them shorter or longer what happens?
