This free website has been named a "Site of the Week" by eSchool News. The site offers free digital games and instructional resources targeted to help middle school science teachers address students' persistent misconceptions. The games and related resources focus on four particularly challenging topics for students: photosynthesis ("The Ruby Realm"), heredity ("RoboRiot"), electricity ("Monster Music"), and heat transfer ("Galactic Gloop Zoo"). The site also features an animated video series that explains why digital games are so appealing to students, offers "No Way!" a classroom activity that helps students develop critical thinking and science literacy skills emphasized in the Next Generation Science Standards, and presents our research on the games and resources.
