Wonderville is a great website for kids on which students can find games, videos, comics, and hands-on activities for learning about science and technology. The gallery of activities, games, videos, and comics is divided into three categories; fun science, awesome tech, and cool jobs.
A couple of the Wonderville games that I like are Reaction Action and Medieval Levers. In Medieval Levers students watch a short animated video about the physics of levers before trying to build their own catapults to use to attack the castle. In Reaction Action students learn about combustible gasses. The object of the game is to collect combustible gasses that can be used to create energy.
Applications for Education
Wonderville's games, comics, and videos can be used by elementary and middle school students on their own. The hands-on activities could be used by teachers as the basis for an elementary school science lesson plan. The hands-on activities include experiments in which students need to record observations.
