This resource requires students to process information on an earthquake. This entails calculating the distance that the recording stations are from an earthquake's epicentre, locating the epicentre, calculating the magnitude, and answering general questions on earthquakes.
A diagram representing an area of a civil emergency is provided and students are asked to identify the geological event that has caused this. Students then give six hazards or problems that could result from this geological event.
Students use the Modified Mercalli intensity scale to assign magnitudes to three described earthquakes. Then they interpret data about the distance from an epicentre, and explain why, from given information, one earthquake might be more damaging than another.
Using data from three different locations, students calculate the time difference between the arrival of P and S waves and the distance of each location from an earthquake's epicentre. Students use these distances to locate the epicentre on a map of NZ.
This resource asks students to apply their understanding of basic wave behaviour at the sea shore to make an inference about waves in a different but analogous context: to predict where the worst damage might occur in an earthquake.
Task: Students read a pH scale to determine how it shows the increasing strength of an acid and a base solution and decide from different pH products what the effect would be on an acidic soil. Assessment focus: interpreting a pH scale.
