On a grid, students enlarge the net for a box by a scale factor of 3.

Students identify which of the three transformations (rotation, reflection, translation) were not used to create repeating koru patterns.

Students use given shapes to cover grids in tessellating patterns.

Students choose the correct trigonometric ratio which would be used to calculate a missing length in two practical problems.

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 practical task has two parts. The first part of this practical requires students to observe the effects of different indicators on different substances. Students use these results to identify if some other substances are acid, alkali, or neutral.

This practical task consists of two parts. Students test various substances with hydrochloric acid, iodine solution, and universal indicator, and then complete a table with their observations. The second part requires students to identify four unknown solids using their tests and results from part one.

Using a stimulus diagram showing plate tectonics, students explain why the following geological features or events; earthquakes, mid-ocean ridge, ocean trench, and volcanoes are present.

Students are provided with a sequence of diagrams showing the erosion of a waterfall by a river over time. Students complete diagrams for two other waterfall erosion sequences. Each waterfall has different combinations of layers of soft and hard rocks.

This practical task requires students to make observations and draw diagrams about diffusion that occurs when food colouring is added to water.

Students are provided with a diagram of a roadside cutting. They are asked to mark the fault line and the youngest rock layer in this cutting. Students then suggest two explanations for the pattern shown in the diagram.

For this practical task students use their knowledge about the properties of gases to explain their observations when they blow up a balloon that is inside a bottle and a balloon that is not inside a bottle.

Students are asked to identify two impending signs of a volcanic eruption and to describe four geological events that are linked to volcanic eruptions.

For this practical task students are provided with four types of plant storage organs. They classify examples as one of these types of food storage organ. Students also look at the tap root and a tuber and describe the main differences between them.

This practical task requires students to test a number of circuits and to give reasons why some of the circuits do not work while others do. Students also look at other circuits and explain what happens to the brightness of the bulb.

This practical task requires students to follow an experimental design that investigates various forms of insulation. They are required to gather results, make a conclusion, and identify the variables.

Students answer short questions to demonstrate their understanding that candles need oxygen to burn.

Students use keywords to label a simple circuit, and then explain how someone would know if the circuit is on or off.

Task: Describe changes to iron as it is heated or cooled. Assessment focus: changes to metals as they are heated and cooled.

Students place five statements in order to show how sound travels from its source to the brain.

Students answer short questions to show their knowledge of heat transfer through metal and plastic spoons.

Students indicate for each of six different variables those that need to be kept the same for an investigation about dissolving different types of sugar.

Students use information on the properties of five different drinks in order to place them correctly into a key.

Students use a list that has some properties of glass to help them answer four questions about glass use.

For this practical task students investigate and report on what they noticed about a model river and how different sized materials are moved by the water.
