This collection of videos, animations and documents comes from the NCSSM AP chemistry online course. Chapter five provides practice and demonstrations related to moles, molarity, and reaction types in chemistry.

For certain mixtures, reactions can be used to determine the relative composition of a mixture. This is illustrated in the following video.

This course introduces the basic driving forces for electric current, fluid flow, and mass transport, plus their application to a variety of biological systems. Basic mathematical and engineering tools will be introduced, in the context of biology and physiology. Various electrokinetic phenomena are also considered as an example of coupled nature of chemical-electro-mechanical driving forces. Applications include transport in biological tissues and across membranes, manipulation of cells and biomolecules, and microfluidics.

Learn how scientists regulate a nuclear reactor in this animation-enhanced essay from the FRONTLINE Web site.

There are many different kinds of energy. Every kind of action needs energy to make it happen.

In this lesson, students will explore motion, rockets and rocket motion while assisting Spacewoman Tess, Spaceman Rohan and Maya in their explorations. They will first learn some basic facts about vehicles, rockets and why we use them. Then, the students will discover that the motion of all objects including the flight of a rocket and movement of a canoe is governed by Newton's three laws of motion.

The purpose of this activity is to demonstrate Newton's third law of motion which states that every action has an equal and opposite reaction through a small wooden car. The Newton cars show how action/reaction works and how the mass of a moving object affects the acceleration and force of the system. Subsequently, the Newton cars provide students with an excellent analogy for how rockets actually work.

This video segment adapted from FRONTLINE looks at nuclear fission as an energy source that can be used to generate electricity.

What happens when a nuclear reactor overheats? This video segment adapted from FRONTLINE looks at the nuclear reactor meltdown at Chernobyl, the worst accident of its kind.

One by-product of nuclear fission is plutonium. This video segment adapted from FRONTLINE takes a look at this toxic element.

This text excerpted from Beyond Engineering: How Society Shapes Technology by Robert Pool and reprinted on the FRONTLINE Web site looks at the impact of nuclear power.

This video segment adapted from AMERICAN EXPERIENCE examines the worst nuclear accident in U.S. history.

Intermediate organic chemistry. Synthesis, structure determination, mechanism, and the relationships between structure and reactivity emphasized. Special topics in organic chemistry included to illustrate the role of organic chemistry in biological systems and in the chemical industry.

Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of reactants. Play a game to test your understanding of reactants, products and leftovers. Can you get a perfect score on each level?

Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?

Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters. This simulation is best used with teacher guidance because it presents an analogy of chemical reactions.

NBC's Lester Holt looks at Newton's Third Law of Motion and the role that conservation of momentum plays whenever players collide on the football field. "Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League.

Equilibrium of biochemical reactions is seldom taught in introductory biology labs. However, equilibrium is an excellent topic for the introduction of simple mathematical modeling into the lab curriculum. When properly done, modeling can allow an exploratory, hands-on approach to equilibrium, as well as teach a valuable application of mathematics. Stella modeling software facilitates the exercise by allowing students to construct sound models without dwelling on mathematical details. This exercise illustrates a modeling approach to reaction equilibrium and some aspects of thermodynamics. We use this exercise in introductory biology laboratories at Clemson University.
