Light travels as waves. Waves can be described by their amplitude, wavelength and frequency. The speed of a wave can be calculated from its frequency and wavelength.

The circulatory system transports substances between the exchange surface and cells. It delivers oxygen and glucose to the tissues for respiration, which is the release of energy to cells.

This section of the lesson module focuses on covalent bonds, which are formed between non-metal atoms that share a pair of electrons. It includes links to a video and a test. Other types of chemical bonds are covered elsewhere in the...

This lesson focuses on static electricity, including how particles can be charged by friction, and electrical forces and why they repel or attract each other. Includes a link to a test.

This lesson focuses on gravitational fields and includes what one is, the formula for gravity force, defining weight, formula for mass, an example of how to calculate gravity force, a practice question, and a link to a test.
