[Free Registration/Login Required] Drag the groups of hydroxy and hydrogen atoms to their proper locations to make a complete glucose molecule.

An interactive display of quasicrystals allows students to study the inner components and molecular make-up of these structures. Since the discovery of quasicrystals, a lot of efforts have been put on finding the locations of atoms...

Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many...

Students explore connections between electric forces and molecules using simulations, and explain energy transfers using conservation of energy. This concept will be explored in the following activities. Activity 1 What makes materials...

An easy to do activity that investigates the basic principles behind chemical bonding. The activity is written in lesson plan format that meets NSES standards.

The page from NASA's The Space Place describes a simple activity, charging a balloon and making it move small pieces of paper. It then goes on to give an excellent explanation of how the activity works, and how it involves ions. This...
