Students interpret the diagrams of mixtures, solutions, and pure substances. Then they draw diagrams to represent other combinations of substances.

Students classify 12 common substances as either a compound, mixture, or element.

Students draw a graph from some information they are given about the heating of meths in a water bath. Students then explain in terms of particles what is happening for the sloping section and the flat section of the graph.

Students use diagrams of substances with labelled atoms to write their chemical formula.

Students answer a multi choice question and draw and explain their understandings about heat convection in a hot water cylinder. Assessment focus: Using science ideas to explain heat convection.

Task: Students answer questions about a soil food web. Assessment focus: reading a food web, systems thinking.

Task: Explain the science messages communicated in a cartoon. Assessment focus: decomposition and photosynthesis.

Task: Use written text about farming's contribution to climate change to complete a flow chart, and answer questions about the two texts. Assessment focus: interpreting, using, and comparing different types of text.

Task: Students answer questions about a Southern Ocean food web. Assessment focus: interpreting food webs.

Students are provided with information about a genetic trait. They develop genotypes for the parents involved and then complete a punnet square for these.

Using characteristics found in peas, students construct two punnet squares and then answer questions on these.

Task: Students interpret a graph to answer questions, and use background knowledge to justify their responses. Assessment focus: control of body temperature in different types of animals.

Task: identify micro-organisms. Assessment focus: using an identification key

This task is about describing the behaviour of light rays.

Students to apply their understanding of basic wave behaviour at the sea shore to make an inference about waves in a different but analogous context: to predict where the worst damage might occur in an earthquake.

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.

Using the principles of fair testing, students identify four factors that could affect the time it takes for electric jugs to boil water.

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.

This whole investigation requires students to find out how spring stretch is affected by different masses pulling on it. There is also a section for planning a similar investigation and a processing section using some provided data.

This practical task requires students to plan, process, and evaluate an investigation on types of fruit and the voltage that each can produce.

Task: Answer two questions about variables in an investigation about insulation and complete a graph. Assessment focus: fair testing.

Task: Investigate mass required to lift a small rock when changing distance from pivot. Assessment focus: levers.

Task: Answer questions about rowing. Assessment focus: levers.

Task: Answer questions about levers. Assessment focus: levers.

Students read a passage about a proposed fair test and then list four variables that need to be controlled.
