Students draw diagrams to show the particle arrangement in a solid, liquid, and a gas. Students then describe the differences in arrangement and movement of the particles for each of these states.
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.
Students explain the function of the veins, waxy layer of the upper surface of the leaf, how the shape of the leaf traps light energy and why the upper surface of the leaf is a darker green than the lower surface.
Task: Demonstrate understanding of the pupil reflex of the eye, and apply this to answering questions about sunglasses safety. Extension questions probe understanding of who decides on and applies safety standards. Assessment focus: effect of UV light on the eyes and how it can be mediated by simple sunglasses technology.
Task: Use understandings about heat energy and insulation to describe how adaptations help Emperor penguins survive in Antarctica. Assessment focus: adaptations for keeping warm in cold conditions.
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: Identify from an experiment the preferred living conditions of slaters, and use a fact file to suggest reasons why. Assessment focus: interpreting results of an investigation.
Task: Identify how the kererū's adaptations contribute to its interactions with its ecosystem, and how knowing about kererū's' adaptations can benefit both it and people. Assessment focus: using understandings about adaptations to consider actions affecting the kererū.
Task: Decide the advantages for survival of both introduced and native frogs' life cycles, explain how climate change could impact on native frogs, and identify level of interest in survival of native frogs. Assessment focus: using information about adaptations.
Task: Using statements from four people decide and justify whether or not each person supports wind farms. Identify which person has a misconception about wind farms, giving a reason. Assessment focus: identifying different perspectives.
Students read an article about an investigation into the sustainable harvest of pīkao and identify key features of the investigation. Assessment focus: interpreting information about how scientists work.
Task: Students suggest ways to stop sand dunes blowing on to farmland, and describe the predicted outcome of their suggestions. Assessment focus: application of knowledge of erosion to a specific situation.
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.
In this activity students progressively build up evidence for and against a new idea in pest control: using bumblebees to transmit a fungicide. Students practise argumentation skills and reflect on how they formulate opinions on environmental issues.
