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.

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-IDA003997

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 ...
