In this practical students are first required to identify as many uses of paper they can think of. Then, using samples of different paper types, they identify particular uses for that type of paper and reasons why the paper is used for this purpose.
Task: Describe and compare some physical properties of plastic objects and identify the properties scientists might use for classifying materials. Assessment focus: classifying using physical properties.
Information on particle size and boiling point is provided for three alcohols. Students use this to place these substances in order of particle size and increasing boiling point.
In this NEMP task students conduct a test to identify whether a number of substances are acid, base or neutral. They also answer a question about neutralising. Assessment focus: testing acid or base.
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.
Using provided data students decide which of three liquids would freeze if placed in a freezer. Students explain what happens to particles when they freeze and how the level changes due to freezing.
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.
Task: Complete a drawing of things found in or near a waterway, and describe relationships between them. Assessment focus: interdependence in a waterways environment.
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 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 compare drawings of a healthy and unhealthy plant, collect data, and decide which data distinguishes them. This is a mathematics/science resource.
