Chemistry

How are atoms arranged in a metallic solid and in an ionic compound? Are the arrangements of atoms random or is there a “system” to it with regular “repeating units? In this two-part lab, students will build models of the three cubic crystal lattice ...

Help students visualize molecular bonding while providing a hands-on model-building experience. This innovative kit utilizes “electron” chips and cut-out element symbols to build Lewis electron dot models for both atoms and molecules. Students are ab...

Molecules have fascinating shapes and patterns! The structure and shape of a molecule influences its physical properties and affects its chemical properties as well. Lewis structures and VSEPR theory offer useful models for picturing the structures o...

There are more than nine million organic compounds! What makes all these compounds different? Introduce the basic structural theory of organic chemistry by building molecules from the ground up using models. In this guided inquiry activity, students ...
