A spatial pattern involving the area of a shape is represented by a table and a diagram. Students describe the rule in words and as an algebraic expression.
Task: Students place in order four beakers of copper sulphate solution from most to least concentrated. They then explain what would happen if two beakers were put together, and explain the term "concentration". Assessment focus: solutions.
Students are given an experimental setup of heating water with a burning peanut and are asked how they could change this in three ways to get a greater temperature increase. Students are also asked to give two important experimental conditions that should remain the same if the experiment was repeated.
Students use substitution into equations to evaluate the number of blocks and total surface areas in shapes of different heights.
The stimulus can be used as a challenging task to try and derive the rules from the spatial pattern. This is classified as Patterns and Relationships.
Students are given a diagram and information on the ratios of black- to grey-coated possums. Students answer questions relating to this information as well as identifying a method that could be used to determine the percentage of each coat colour.
In this task, students look for patterns in electron arrangement in the periodic table. They use their ideas to place missing elements in the table, answer some questions about the patterns, and use the patterns to predict the properties of some elements.
Students draw the next two triangles in a spatial pattern, calculate the areas of a range of triangles, work out the height of a triangle given its area, and write a rule for the pattern.
Students answer questions about the size of a balloon as the air temperature changes. The resource assesses students' understanding of the effect of temperature on gases.
Explain how to test if a solution is an acid or not, and describe and explain what happens if rusty nails are put in an acid. Assessment focus: acid reactions.
Using information about comets, students label a diagram of a comet and draw the orbit of a comet and the position of the comet in two places in its orbit.
This task is about using evidence to find the main idea of a text. Students read a narrative text with a Māori context, find two groups of details, then select the main idea from four choices. Note that the text deals with the hunting and slaughter of pigs, which may be a challenging concept for some of your students. SJ-4-2-2004. Text provided.
Task: Read a short piece of narrative. Identify and explain the behavioural adaptations of oystercatchers. Assessment focus: interpreting text to identify behavioural adaptations and their purposes.
Students prepare a talk for a group or the class about a book. The assessment focus is on both content and delivery. ARB scoring guides A and B are suitable for this task.
