This fascinating video details the journey that a group of friends made in Nevada. Their aim was to illustrate the solar system to scale.

• 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.

This YouTube video investigates the structure and composition of the sun.

In this lesson you will learn about:

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

This online resource investigates the internal structure, outer layers and surface features of the sun.

These four short online lessons cover the following:

• What is the sun?
• Interior of the sun
• Outer layers of the sun
• Surface features of the sun

This online resource explores the terrestrial, or inner, planets - the planets closest to the sun: Mercury, Venus, Earth and Mars.

This online tutorial will provide you with some guidelines on how to interpret both topographic and geologic maps.

This online resource investigates the features and topology of the ocean floor, the effects of wave erosion and the landforms created by coastal depositions.
