Chemical Composition of Everyday Objects

A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

Radiation has numerous real-world applications, some of which are relatively safe while others can be extremely hazardous. In this nuclear chemistry project, young scientists choose a practical use of nuclear reactions to research in...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of experiments, pupils...

Biology learners should understand a few chemistry basics. Here is a worksheet that introduces them to the concepts of chemical reactions, molecular bonding, and the unique combination of properties that make water vital to life....

In this chemistry worksheet, test takers answer 60 multiple choice questions on topics related to chemistry from balancing equations to calculating moles and molecules of compounds. They name formulas, they convert, they solve problems...

Chemical and physical properties give compounds an identity. Learners use the identity of a compound to predict what it is. By performing different tests like solubility, flame, heat, and reactions, individuals attempt to identify an...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Everything around you is related to chemistry and more specifically, the energy within a system. The video explores how energy, in its different forms, changes after conversion — given off as heat or absorbed as heat  in chemical...

Finding new drugs has been likened to finding a needle in a haystack. How do pharmaceutical companies do it? One of a small series of four informative leaflets examines combinatorial chemistry, the method at the forefront of new drug...
