Light and the electromagnetic radiation spectrum. Wave and particle-like behaviour, and how to calculate the wavelength or frequency of a light wave.

A discussion on how energy can't be created or destroyed in an isolated system, and works an example of how energy is transformed when a ball falls toward the Earth.

An explanation of how LOL diagrams allow us to visually represent what we mean by conservation of energy as well as what we mean by an energy system.

The potential energy between two objects due to long-distance forces can be thought of as being stored in a field. When the objects move due to the field forces, the energy stored in the field decreases

This online activity is a math game on rounding numbers. 

This is an online activity that provides you with various exercises on rounding whole numbers.

Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system’s total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms.

An exploration of how the area under a force vs. position graph equals the work done by the force and solves some sample problems.
