In this unit you will learn about different materials by investigating and observing the behaviour of their properties. This will include learning about the differences between metals and non-metals; whether they are isolators or conductors of electricity and heat, whether they are magnetic, how dense they are and whether they are acidic or basic.

Outcomes

By the end of this course you will:

• Be able to define the 'reflection of light'
• Understand the difference between reflected and incident rays
• Be familiar with the two types of reflection viz.: regular and irregular reflection
• Have an understanding of the laws of reflection

According to Creative Commons there are over 1.6 billion openly licensed teaching and learning resources available on the internet. Open Educational Resources (OER) are quality, free educational resources, that you can use without having to ask for permission, and that can be adapted to better suit local contexts and needs.

Many educators and developers don't know how to efficiently search for and identity useful resources. Some throw up their hands in horror and give up when tasked with finding suitable resources on the Internet. In this tutorial, we are committed to providing you with a search strategy for open content to ensure that you quickly find open resources. Let us begin!

On completion of this unit of study you will be able to:

• Decipher open licenses i.e. identify rights and permissions contained within Creative Commons licences attached to open content.
• Search for open content using common tools and filters such as on Google Advanced Search and the YouTube Creative Commons filter, as well as specialized services such as Creative Commons Search to find open media.

• Describe a molecular model for solids, liquids, and gases.
• Extend this model to phase changes.
• Describe how heating or cooling changes the behavior of the molecules.
• Describe how changing the volume can affect temperature, pressure, and state.
• Relate a pressure-temperature diagram to the behavior of molecules.
• Interpret graphs of interatomic potential.
• Describe how forces on atoms relate to the interaction potential.
• Describe the physical meaning of the parameters in the Lennard-Jones potential, and how this relates to the molecule behavior.

• Describe characteristics of three states of matter: solid, liquid and gas.
• Predict how varying the temperature or pressure changes the behavior of particles.
• Compare particles in the three different phases.
• Explain freezing and melting with molecular level detail.
• Recognize that different substances have different properties, including melting, freezing and boiling temperatures.

In this lesson you will learn about:

• The structure of matter
• Kinetic theory
• The three states of matter
