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.

This YouTube video explores both passive and active solar energy.

This online resource introduces the geocentric and heliocentric models. Exoplants, planets and their motions, planetary orbits, the role of gravity and how the solar system was formed are also covered. 

This short YouTube video introduces you to the planets which make up the solar system.

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.
