For this practical students are required to investigate how the use of pulleys affects the effort force needed to raise a load. Students gather results, write a conclusion, and describe two situations in which a pulley system would be useful.
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.
Task: Explain how a change in the cockle population has affected one or more organisms in a food web in the short and long term. Assessment focus: Sorting observations and inferences; reading food chains and; using a food web diagram to predict impact of change.
Task: Identify how features/adaptations of a starfish help it survive, and decide whether the amount of evidence from scientists' observations supports or does not support their theory/inference. Assessment focus: using observations as evidence to inform theories.
Task: Choose images to enhance a science text about an adaptation of kererū, compare the messages of images, and reflect on the role of illustrations in science texts. Assessment focus: using and interpreting images in science texts.
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.
Task: Read information and compare the special features that influence the chances of survival of black robins and fantails. Assessment focus: interpreting text to identify risk factors for survival.
Task: Describe what happens to ice in a glass of water, giving reasons, and explain where water forming on the outside of the glass comes from. Assessment focus: changes of state.
This practical task requires students to follow instructions for making a 'green fridge' to determine its efficiency. Students collect and record data from their investigation and answer questions.
Explain what affects the distance travelled by toy cars, and why they eventually stop. Assessment focus: science explanations using ideas about forces and energy.
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 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 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.
Task: Use pictures to identify special features of various fish and make predictions as to likely habitats based on these features. Assessment focus: purpose of adaptation in fish.
