Glaxo Smith Kline’s Active Science offers fifteen interactive games covering a range of science topics. There are games appropriate for elementary school, middle school, and high school students. The games for younger students appear at the topic of the Active Science list and the games for older students are at the bottom of the list.

The Interactive Periodic Table is a game designed to help chemistry students practice identification of the elements. To play the game students are given some clues about an element’s properties. Using those clues the student has to place the element in the correct place on the table.
