• TLF-IDA003461

The soil moisture sensor project integrates science understandings and computational thinking to solve a problem about sustainable watering practices. This lesson was devised by Trudy Ward, Clarendon Vale Primary School, Tasmania.

• TLF-IDA003902

This activity invites students to explore the process of seed germination and the early phases of plant development. The activity includes a list of tools and materials required, what to do and notice, an explanation for the underlying science of what students observe and suggestions for further activities.

• TLF-IDA003970

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 ...

• TLF-IDA003967

This short video demonstrates how to determine the streak colour of a mineral sample. The video shows how to rub a mineral sample across a streak plate, and how to use a streak colour chart to help identify a mineral. The video also shows the difference in streak colour for pyrite (fool's gold) and real gold.

• TLF-IDA003976

This video introduces earthquake monitoring using seismometers and seismographs. It also features the National Earthquake Alert Centre. Students are asked to try making earthquakes at home using the accelerometers in their smartphones.

• TLF-IDA003990

This 58 page booklet explores geological timescales in the context of the Australian continent. Each section discusses a single geological time interval, and outlines the major geological, climatic and biological events which occurred in that interval, including continental drift, the break-up and amalgamation of continental ...

• TLF-IDA004004

This activity builds understanding of sonar technique and applications through processing and plotting data to discover a seafloor feature and by bouncing balls on different surfaces and analysing rebound, relating this to ground hardness then extend understanding to 'backscatter' in bathymetry surveys. It is suitable for ...

• TLF-IDA003995

This activity introduces lava viscosity and influence on volcanic cone shape. The download includes background information for teachers and an activity sheet for students. The activity involves making lava slime and racing this down a slope. Participants are asked to predict how lava viscosity might influence volcanic shape ...

• TLF-IDA004618

In this lesson students explore the dynamics of flight by examining animal adaptations and apply their learning to think like an aeronautical engineer and design their own glider

• TLF-IDA004621

In this lesson students think like geotechnical engineers, exploring the properties of sand and the ways in which those properties can be used in building and construction.
