This online resource outlines the seven characteristics that define all living things.

It provides details of all seven things, and contrasts this with characteristics of non-living things.

This online resource looks into the concept of radioactive decay.

The resource is a lesson that uses M&Ms or Skittles as a model to examine the rate of decay of unstable nuclei.

The lesson allows students to grasp the concept that the exact time a certain nuclei will decay cannot be predicted, but that the overall decay of the radioactive element in a solid can be predicted. A printable worksheet is linked to from the web page.

This online resource looks at different allotropes of carbon.

The resource details a lesson to compare the molecular structure of diamonds and graphite.

The lesson examines how the structure of molecules can affect the physical characteristics of the material.

This online resource looks at acid-base reactions.

The resource provides a range of activities to do with some key chemical concepts relating to hair care, shampoos and conditioners.

The activities place ideas about surfactants, acids, and bases in an everyday context, using activities ranging from practical experiments to role play and a class survey.

This online resource investigates the gravity tower at Gingin near Perth.

The resource is a video from the ABC television show Catalyst and shows several objects being dropped from the 45 m high tower and their acceleration due to gravity is compared.

It also demonstrates that an object with a chain attached, like a bungee cord, can actually accelerate faster than gravity. This is then compared to the cracking of a whip where the whipping motion accelerates the end of the whip to a speed faster than the speed of sound.

This online resource demonstrates the size of atoms and the way they move.

The resource details three simple experiments and models that can be used to demonstrate the size of atoms and the way they move.

There are also instructions on how to make models of water, ice and salt.
