This video introduces the National Earthquake Alerts Centre. The video explains that earthquakes are detected by a network of seismometers; each station sends seismic information for analysis and checking by seismologists on duty. The video describes the types of wave forms in earthquakes and the sequence of events in ...

This activity demonstrates how much water expands when frozen. Students quantify water's expansion when it freezes and establish how this can lead to weathering (breakdown) of rocks in areas exposed to frequent freezing and thawing temperatures. It is best to set up the demonstration one day ahead and examine the results ...

This activity invites students to investigate why, when you touch a variety of materials, some will seem warmer or colder than others, even when they're at the same temperature. The activity includes a list of tools and materials required, what to do and notice, an explanation for the underlying science of what students ...

This activity invites students to calculate the acceleration of gravity using simple materials, a cell phone, and a computer to record, watch, and analyze the motion of a dropped object. The activity includes a list of tools and materials required, assembly instructions, what to do and notice, an explanation for the underlying ...

This activity invites students to make Cranky Contraptions, kinetic sculptures that animate a character or scene when a handle is turned. These automata are powered by a simple crank slider mechanism which provides the basic motion. Everyday materials around can be repurposed into these contraptions. The activity includes ...

This short video examines the process of liquefaction and its impact on buildings and other structures. The video encourages students to investigate some of the ways engineers lessen the impact of earthquakes on buildings and to make their own liquefaction demonstration and extend it into an inquiry activity.

• TLF-IDA004557

In this lesson sequence, students investigate how properties of materials determine their use. Students identify a range of natural materials used by Aboriginal and Torres Strait Islander Peoples for a specific cultural purpose. There is an optional ‘maker hour’ for students to produce, implement, test and evaluate a shelter ...

In this activity, students use a story of a fictional river to explore the impacts of various land uses on the ecological health of a river. This demonstration can be used to introduce science or geography concepts related to your local catchment e.g. land uses, water cycle, human impacts and contaminants or waste in river ...
