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.
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 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 provided with drawings of the main types of fingerprints. Students then make their own fingerprint and those of three other students. They then classify and describe the differences between these prints.
Students are provided with some information about testing leaves for starch. They are required to match the steps in the process with their purpose, and to explain what substance is present that turns iodine blue-black.
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.
Pictures are given of the life cycles of three different animals (hawk, turtle and deer). Students identify which stage the animal's survival is most in danger and give explanation of why it is not safe. Students also give one special feature that helps this animal survive at this time.
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 are given diagrams of an experiment on photosynthesis using pond weed. Students are asked to put the diagrams of the experiment into the correct order, to give an aim, identify the gas produced, name the process in plants that produces this gas, and to write a conclusion for the experiment.
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.
