10 Science Online Game Collections Kids Can Play in Their Free Time

Science in particular has a great many subjects which benefit from visual models and animated examples.  Furthermore, kids of nearly all ages naturally gravitate to things that resemble games since they understand and respect their mechanics and rules.  Take advantage of this match made in heaven and look over these curated collections of web-based science games that kids can play at school and at home to reinforce what they are learning in class.  Since science often gets less time in the limelight than subjects such as language arts and math, these games are also a great way to get in some extra practice that you may not have freedom to devote direct teaching time to.
