Here is a unique assigment: compare and contrast ionic and covalent compounds in an extensive data table and then analyze Lewis dot structures in antoher. Three columns are to befilled in: "characteristic or feature," "applies to ionic...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Four activities immerse beginning chemists into the world of elements. They examine the periodic table, use cobalt hydroxide to learn about chemical formulae and valence electrons. Also, they name binary compounds and examine the...

Communicate chemistry clearly with a concise guide to writing chemical equations. It covers everything from the parts of a chemical equation to the different types of reactions that budding chemists may encounter.

Balancing chemical equations is difficult even for top learners, and oxidation-reduction reactions can be the most difficult to understand. Using the half-reaction method, the instructor demonstrates four examples. Learners can watch the...

Chemical reactions are happening all around us every second of every day, but what exactly causes these changes to occur? Using easy-to-understand analogies, this video explains how the concepts of enthalpy and entropy determine the ways...

The first lesson in a 35-part video series explains how orientation and energy determine a successful collision reaction. Scholars examine the requirements for a collision reaction to take place and come to understand that the...

How are chemical reactions like dating? A collision must first occur! In this hilarious approach to speeding up chemical reactions, viewers find out that five changes can increase the rate of reaction: smaller space, increased number of...

Thinking back to the last time you taught a lesson on chemical changes ... was there no reaction? Check out an explosive video to put some spark back in your instruction! The narrator of the video guides you through the...

It's easy to take for granted the the importance of electricity in modern society, and even easier to overlook the environmental cost that is paid for all that energy. Watch as this video explores the detrimental impact...
