Why not review for that chemistry test with a little healthy classroom competition? With a fun and interactive Jeopardy-style game, you can adjust the number of teams, keep track of scores, and even make your own test if the provided...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Behold, the electron is discovered! Take young scientists on a journey back through time to examine JJ Thompson's famous experiment using a Crooke's tube. Pupils manipulate the charge on the apparatus' horizontal plates, observe cathode...

Is your class in a quandary over quantum numbers? Change things up by adding games to the mix! Science scholars discover the shape, number of electrons, and number of orbitals in the s, p, and d sub-shells using an interactive.

Naming complexes can be, well, pretty complex! Simplify a study of ligands using interactive puzzles. Junior chemists match up the name, formula, and complex name, then solve a series of logic games with the information.

Things are really shaping up! Provide young chemists with polyatomic ion practice using an interesting interactive. Individuals complete puzzles focused on molecular geometry and complex ions.
