Modeling chemistry

• To discuss main topics in introductory chemistry

• To facilitate students' understanding through the use of models and analogies

This program introduces the basic building blocks of matter – atoms – and focuses on their structure, the periodic properties of elements and their ability to bond with each other. The program shows teachers and students in a variety of classroom activities that challenge students to understand concepts of atomic structure, periodicity, bonding and moles through useful mental models of atoms. It follows the development of these concepts through history and their use in modern technology.

"I think an atom is something really, really small, about... mmm… this big…."

"So often when you're learning chemistry, it seems that you are learning laws and rules that don't have much application in real life. All you have to do is look around and you will see that chemistry is basically everywhere. That table in front of us is made up from a collection of atoms; it's important to understand how they are arranged and how bonds and energy hold them together."
