Outcomes

In this course you will learn about:

1. Expanding brackets.
2. Factorising by grouping.
3. Factorising by finding the difference of two squares.
4. Factorising trinomials.
5. Simplifying algebraic fractions

This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work. 

Outcomes

In this course you will learn how to:

1. Use exponential notation and exponential identities.
2. Multiply exponents.
3. Divide exponents.
4. Raise a power to a power.
5. Change fractional exponents to radical form.
6. Simplify surds.

This video explains how to find factors.

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

Three activities which illustrate the law of exponents.

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

The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!

The model also helps us to understand what happens to the particles when matter changes from one state to another.

In this unit, you will explore the three phases of matter and then look at the properties and differences between them. You will explore their shape, volume, and kinetic energy.
