Some online science games for kids are "Magnets" and "Let it Glow." There is also an animal-inspired science game for kids called "Habitat Adventure: Panda Challenge."
"Habitat Adventure: Panda Challenge" is a fun science game for kids who enjoy animal games. The player tries to protect giant pandas and the habitats they live in. The player uses field guides, a camera and binoculars to inspect the habitat and make decisions about how to make it better.
With "Magnets," the player matches three or more magnets based on their colors in order to destroy them. This game is appropriate for kids of all ages and is relatively easy to play. In "Let it Glow," players try to bring light to a light bulb. They drop transmitters in certain places to get connections from lightning bolts.
