An introduction to the difference between distance traveled and displacement.

Using a one-dimensional number line to visualise and calculate distance and displacement.

The Earth behaves like a giant bar magnet and as such there is a magnetic field present around it. The Earth’s magnetic field is thought to be caused by flowing liquid metals in the outer core of the planet which causes electric currents and a magnetic field.

The idea of the electric field, how it's useful, and explains how the electric field is defined.

Use the dynamic worksheet to practice simplifying expressions with fractional exponents, rewriting them as radicals.

This video explains how to solve inequalities.

Three activities which illustrate the law of exponents.

This is a simple video which describes how indices problems are solved using simplified laws.

In this lesson you will learn about:

• The concept of magnetism
• Be able to identify magnetic and non-magnetic materials
• Identify properties and types of magnets
• Understand that metals can be magnetised and de-magnetised
• Understand that magnets have a magnetic field
• Understand that the Earth has a magnetic field
