Smoking, alcohol, drugs, and solvents are the topic of this informational presentation. The causes, effects, and health issues that arise from illicit drug use are all covered. While this appears to be a learner-driven presentation, it...

Hydrogen bonds, and polarity are described in this PowerPoint, and the reasons for tension and cohesion associated with water.  The states of water under certain conditions are explained with information about the changes in...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.

What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Advanced techniques for the lab use of chromatography are detailed here and your students will learn the specifics of separating molecules using a staionary and mobile medium. Diagrams of the equipment used and some facts about how...

Amateur chemists define and describe properties of solutions, compare solubilities, explain how solutes affect freezing and boiling points, describe acid and base properties, and more! This educational PowerPoint provides information and...

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

Chemistry and biology work hand in hand, without one you literally wouldn't have the other. Using a presentation, individuals learn about plant cells, animal cells, cell responses, macromolecules, DNA bases, and so much more. A worksheet...

Thin-layer and gas-liquid chromatography are introduced in an intelligible presentation. Paper chromatography is also listed as another type of chromatography, but it is not explained. If you are particular about appearances, there are...

Titration, and the lab skills that are needed to support it, is detailed here, with the reasoning behind standard solutions, concentration and volumetric analysis covered. Your young lab assistants will learn the skills of determining...
