Check out the contest instructions for details:
The contest is simple--just do what I do quite often. Read a non-fiction science book and make a video! Oh, you have to be a kid or teen. Just making that clear. Age 8-12 can enter Kids Read Science and ages 13-18 can join Teens Read Science. We will be thrilled to see you all be creative and articulate. Tell us what you learned in less than five minutes.
Anyone anywhere in the world can submit an entry. We have prizes, too! But, for now, with our limited legal knowledge, we can only distribute those in the US. Don't worry, we're going to try to figure something out for everybody else.
You can start with my previous post to get ideas about readings (at least for teens), and feel free to add ideas in the comments here and on Joanne's blog.
