• 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-IDM019066

This is a student digital resource that contains interactive materials relevant to a study of light, sound, and electricity. This resource contains a rich array of digital interactive activities, simulations, video clips, supportive information and notebook questions, and is divided into several parts including sections ...

• TLF-IDL8970

Test your understanding of the nature of solids, liquids and gases. Compare levels of magnification. Identify substances made of only one type of atom or molecule. Decide whether a substance is a solid, liquid or gas by looking at its particles. Identify substances based on their particle behaviour. At the end, you can ...

• 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-IDL9128

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. This learning object is the first in ...

• 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-IDM019065

This is a student guide that explores many aspects of light, sound and electricity including how they are each transmitted and their contribution to modern societies, as well as material on the wave and particle models. This resource is divided into different parts with each containing information, images and diagrams, ...

• TLF-IDM019067

This is a teacher guide containing material to support the planning and implementing of lessons for a unit on the science of light, sound and electricity. It covers topics such as the wave and particle models, how light and sound are transmitted, and electromagnetic radiation and its uses in modern society; and includes ...

• TLF-IDM018350

Have you ever wondered why boiling water has bubbles? Discover with Dr Karl how the bubbles form, then watch what happens as Ruben the Surfing Scientist adds coffee to water he has boiled without bubbles. Spectacular, but dangerous!

• 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 ...
