  • Diagram of a circuit showing a battery with leads on the positive and negative side and a lightbulb in the middle. Reduction. Caption: During this process, one substance must gain electrons,

    Every portable electronic device is fueled by chemistry, specifically through oxidation-reduction or redox reactions. In redox reactions, one compound gains electrons (reduction) and one compound loses them (oxidation). Chemists can set up reactions so that electrons are forced to move in a certain way to create an electrical current. Metals often play a key role in redox reactions, which are essential to all aspects of chemistry, particularly in many biochemical processes. Part of the series Chemistry: Challenges And Solutions.

  • Waterfall greenery in the background. Caption: Weathering occurs all around us.

    In this video, students will learn about the two major types of weathering: mechanical and chemical. These forces alter the shape and composition of rocks. Students will also explore the different types of soils, soil properties, and soil profiles. Other topics covered include oxidation, soil formation, soil texture, horizons, leaching, subsoil, soil conservation, and groundwater.

  • Rocky streambed between snow covered banks. Caption: eventually causing them to split apart.

    Everyday, real-life examples demonstrate the processes of weathering and erosion. Easy-to-understand examples of weathering help students differentiate between the processes of mechanical and chemical weathering. Footage of weathering and erosion processes help students grasp how each process alters the environment. Important terminology includes: mechanical weathering, landslides, abrasion, freezing, thawing, chemical weathering, oxidation, acid rain, moving water, wind, and glaciers.

    3D model of the atom Gadolinium

    Gadolinium is a chemical element with the symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is only slightly malleable and is a ductile rare-earth element.

  • Illustration of a cat knocking over stacked dominoes that then fall as one hits the next. Caption: A catalyst is a substance that jump-starts a chemical reaction without getting involved in the reaction itself.

    A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Topics covered include precipitation reactions, oxidation-reduction reactions, kinetics, equilibrium, and nuclear reactions. Part of the "Chemistry" series.
