Students read some information about testing the absorbency of different papers. They outline two features that need to be kept the same if the tests were to be fair.
For this practical task students use their knowledge about the properties of gases to explain their observations when they blow up a balloon that is inside a bottle and a balloon that is not inside a bottle.
This practical task requires students to sort some common items from hardest to softest. Students then explain a test that they used to help determine this.
For this practical task students complete a table of observations on nine common materials. Students then use their results to group the materials according to similar properties.
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 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 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 a sequence of diagrams showing the erosion of a waterfall by a river over time. Students complete diagrams for two other waterfall erosion sequences. Each waterfall has different combinations of layers of soft and hard rocks.
Students are given a diagram of a glacier, and asked to identify natural hazards and the possible effect of increased temperature on the position of the glacier snout.
This practical task requires students to plan a method to determine which magnet is the strongest. Students carry out their plan, record results and write a conclusion.
For this task students are provided with a diagram showing the landmasses that originally made up Gondwanaland. Students are required to identify and use their own knowledge to indicate the evidence which indicates that these landmasses were once joined together.
Students are provided with drawings of three methods to collect gases and the characteristics of four gases. Students match the gases with the method of collection that would need to be used.
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 provided with some information on the diet of eight NZ birds. Students use this information to fill in a table that identifies which birds are herbivores, omnivores, and carnivores.
Students are provided with four diagrams of different types of fossils. Students are asked to explain the type of information each of these fossils could provide.
Students list advantages and disadvantages of recycling. The assessment focuses on students' ability to identify impacts on the environment and its inhabitants (including people).
