Students are asked to identify a solid, liquid, and a gas. They are also asked to write down two things that are generally true for each of these three states of matter.
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.
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.
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.
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.
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.
