Khan Academy: Introduction to Circuits and Ohm's Law

Take a very basic understanding of circuits and develop a strong understanding of the parts and function of a circuit. This activity is developed to be an independent exploration of circuits from the basics to series and parallel models....

An introduction to entropy and its relationships to various states for a system. [7:27]

Video provides a basic introduction to the phenomenon of light, the electromagnetic radiation spectrum, wave and particle-like behavior, and how to calculate the wavelength or frequency of a light wave. [9:36]

Introduction to how groups of organisms evolve and how natural selection can lead to evolution. [17:39]

Students will explore the basics of dc circuits analyzing the light from light bulbs when connected in series and parallel circuits. Ohm's Law and the equation for power dissipated by a circuit will be the primary equations used. Using...

Learn the definition of partial pressure and see Dalton's law of partial pressure. Find out how to calculate the partial pressure of a gas in a mixture from the total pressure and partial pressure of the other gases in the mixture. [6:51]

Introduction to the reaction quotient Qc, and comparing the reaction quotient with the equilibrium constant to predict how concentrations will change. [7:36]

Introduction to redox in cellular respiration. Provides an overview of how cells break down fuels and looks at some of the electron transfer reactions that are key to this process.

An introduction to buffer systems, which regulate pH in blood. [6:20]

Review the key terms, equations, and skills related to Ohm's law, including how electric potential difference, current, and resistance are related.
