This practical task requires students to first plan how they could find out which liquid flows the best. Then they carry out their plan, record their results, and write a conclusion.
Students are given some solids and liquids for this practical task. They plan how they would find out which liquids are solvents for any given solid, carry out the task, and write a conclusion.
Task: Students play a tag game that simulates the relationships between elements within a waterway and discuss how different scenarios impact on the populations living there. Assessment focus: changes within a habitat affect everything living there.
This task requires students to order four photographs of the life cycle of the Paradise Duck. Students describe the changes that have occurred in each part of the lifecycle. NOTE: It is intended that this resource be used in colour.
This practical task requires students to order five photographs of the life cycle of a Harrier Hawk. Students describe the changes that have occurred in each part of the lifecycle. NOTE: This resource is intended to be used in colour.
This practical requires students to place four photographs of kākāpo at different times in their life cycle in order from youngest to oldest. Students describe how the kākāpo changes from each part of the life cycle to the next. NOTE: This resource is intended to be used in colour.
Students are given an outline of a fair test. They are asked to identify the aim, variables to be controlled, how to judge the results, and an aspect of replication.
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.
For this practical task students investigate water (and dye) movement in a plant when the stem of a daisy is cut lengthwise into three sections. Students record their observations and then explain their results in a scientific way. Key words have been provided.
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.
Task: Students use an image of an Australian lizard to explain what purpose is served by the lizard's tail looking like its head. Assessment focus: features for survival.
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.
Students are provided with six drawings of different types of insects. They use the drawings to explain two features of insects and to explain differences between the insects illustrated.
Task: Order fruit according to size and number of seeds, make a generalisation about the pattern and use this to predict whether a fig has small or large seeds. Assessment focus: pattern seeking.
