Teachers! The holidays are nearly upon us, and you know what that means: time to tweak your lessons for the next term. As you develop your curriculum and put the finishing touches on your upcoming units, we thought you might like the chance to win a sweet, new Macbook Air or some gift certificate cash for what you'd be doing anyway.

We want teachers to show off the hands-on projects they use with their students. But even if you're not a teacher, we want to see your project if you have a great way to teach subject-verb agreement, mitosis, waves, the ramifications of starting two-front wars in Asia, tessellations, or anything else that someone might teach in a formal setting. This contest is open to Instructables, Photos, Videos, and Guides with a learning objective explicitly stated in the introduction.
