• TLF-IDL5825

Test your understanding of the particle nature of matter. From a number of particle-level views of substances, choose the one that fits the type of matter required: solid, liquid, gas, pure substance, mixture, element, compound. For example, distinguish an element from a mixture and a pure compound. This learning object ...

• TLF-IDL9122

Heat ice and record the temperature and states of water at specified times. Plot a graph of temperature against time and relate sections of the graph to the states of water. Observe animations of water particles over time and explain the shape of the graph in terms of particle theory. Predict the shape of the graph when ...

• TLF-IDL9126

Select a substance such as iodine and explore how physical changes of state can be brought about by supplying heat energy to the substance. Observe what happens when heat energy is removed. Observe the changes of state at both the physical and particle levels. Explain the different properties of solids and gases in terms ...

• TLF-IDL9127

Select a substance such as liquid water and explore how physical changes of state can be brought about by supplying heat energy to the substance. Observe what happens when heat energy is removed. Observe the changes of state at both the physical and particle levels. Explain the different properties of liquids and gases ...

• TLF-IDL1490

Experiment with phase transformations of water. Heat a block of ice and a beaker of liquid water. Predict changes to the molecular structure and molecular motion. Look closely at movement of the water molecules, especially at the surface. Explore relationships between temperature, molecular speed and states of matter. This ...

• TLF-IDL10380

Experiment with some gas trapped in an air chamber. Notice how the gas is made of particles. Investigate the speed and collisions of the air particles. Discover what happens to them as you change the temperature. Observe how this affects the properties of the gas. For example, measure the change in pressure as you heat ...

• TLF-IDM012513

This PDF unit of work is one of a series of resources accessible by searching the list in the series.It includes two teaching and learning sequences: 'Water journeys' focuses on the water cycle, and 'Pure water' focuses on the processes and people involved in creating and managing drinkable water. It provides Australian ...

• TLF-IDL9129

Predict the shape of the graph when water vapour is cooled to solid ice. Observe physical and particle animations of the changes that occur during cooling and confirm prediction of graph shape. This learning object is the second in a series of two sequential objects that are also available as a combined learning object.

• TLF-IDL1493

Experiment with phase transformations of water. Heat a beaker of water to boiling point. Predict changes to the molecular structure and molecular motion. Look closely at movement of the water molecules, especially at the surface. Explore relationships between temperature, molecular speed and states of matter. This learning ...

• TLF-IDL10381

Experiment with gas trapped in an air chamber. Change the size of the chamber, add or remove gas and notice how the gas pressure changes. For example, double the pressure by halving the volume. Control the pressure by balancing the volume of the chamber with the number of gas particles it contains. This learning object ...
