Khan Academy: How to Use the Shortcut for Solving Elastic Collisions

Keep your hands on the wheel—at all times! Scholars learn why pilots use a flight computer through a high-flying demonstration. Making calculations for speed, distance, or time is automatic if you know how to use a flight computer. 

A topographic map can be challenging to read. This guide explains how to decipher one and how to use a magnetic compass to orient yourself to the landscape. It also explains how to use GPS coordinates.

Learn how to identify heart murmurs. [9:01]

In this video,learn how to solve elastic collision problems the hard way. The hard way means using the conservation of momentum and conservation of kinetic energy by substituting one equation into the other and solves for the final...

Teach the class how to use a microscope to identify bacteria in food. Scholars explore the different parts of the microscope and learn how to determine total magnification. They walk step-by-step through the procedure of preparing slides...

Understand how to use a redox reaction to construct a galvanic/voltaic cell to produce a flow of current. Idendify the flow of electrons and ions, and recognize the role of the salt bridge. [5:56]

In this science simulation, students learn how to use a microscope as they investigate bacterial contamination in a sample of yogurt.

This resource provides a summary of some fundamental math and science concepts that will be helpful in learning chemistry. Links are provided to help you learn or review the material on Khan Academy.

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]

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]
