In this fun, free online game, players investigate 8 different "cases" – each one a child like them, who suffers from low energy, an unhealthy diet, or weak teeth and bones. Players investigate these cases by exploring the characters' environments, and helping them choose healthy foods or find fun ways to be more active.
Solving a case unlocks 3 fun mini-games, all of which reinforce the healthy habits that players have just learned.
The accompanying teaching guide (making this an excellent resource for educators as well as parents!) says that the game was designed for grades 4 through 6, but I think kids between the ages of 8 and 12 would be able to handle it.
