Jefferson Lab is a great place to find educational online games and puzzles. I discovered this resource when one of my students played “Who Wants to Win $1,000,000?” during some free computer time this afternoon. The games and puzzles are primarily designed for math and science with one word game thrown in for good measure.
Applications for Education
The games from Jefferson Lab are great practice for applying science and math knowledge to problem solving. Jefferson Lab also has a great Teacher Resources page full of lesson plans for hands-on activities, study pages, and reference materials.
