Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Substances with the same empirical and molecular formula must be differentiated by their structural formula. Part two in a series of 36 has pupils using chemical formulas to calculate how much of a compound is present in a given...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Here's a presentation that not only covers momentum, impulse, conservation of momentum in both one and two dimensions, angular momentum, torque, and the moment of inertia, but offers many applied guided practice problems as well.

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...
