For this practical task students are assessed on their ability to record their observations of the decomposition of a cut slice of pumpkin over a two week time period.
A report about a topic of local, national, or international interest is prepared. The assessment focus is on opinions and information from the media. ARB scoring guides A and B are suitable for this task.
Students identify the variables to be kept constant, and the variable to be different, when they plan a fair test to show if green plants need light to grow.
Students are given information and a diagram about a drink bottle overflowing when it had been put into the freezer. Students are asked to explain why this happened and how they could prevent it.
Students identify the appropriate type of graph for a statistical investigation about dice throws. They also justify the use of a histogram for an investigation about heights of people, indicating their understanding of discrete and continuous data.
Students complete a table showing the number of matchsticks used to build a series of pentagons. They identify the number of matchsticks required for a given pentagon and state the rule as an word equation.
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.
