Students use a diagram of a cutting showing exposed rock layers to answer questions about their formation, age, and geological history.

Students are provided with nutritional information on three different types of milk. Students use this information to answer a number of questions.

For this practical task students are assessed on their understanding of the life cycle of a butterfly by putting pictures (of eggs, caterpillar, pupa, emerging butterfly, and butterfly) into the correct sequential order and answering some questions.

Task: Students differentiate between simple observations and inferences, and between observations that require measurement and those that do not. Assessment focus: observing scientifically.

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.

Students complete tables of energy use.

Students are provided with information and data on different makes of soccer balls. Students answer questions on fair testing, and write conclusions from the given data.

Students construct three different sized parachutes from plastic bags. They then carry out a fair test to see which sized parachute is the most effective. Students answer questions about fair tests, collect and record their results, and make a conclusion.

This practical task requires students to follow an experimental design that investigates various forms of insulation. They are required to gather results, make a conclusion, and identify the variables.

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

Task: Predict whether given objects will float, investigate, then record and explain results. Assessment focus: flotation.

This practical task requires students to record temperatures of various areas in the school and to suggest reasons why some areas are warmer or cooler than others.

This practical task requires students to use a plastic comb and wool to generate static electricity. Students investigate different materials to find those that are attracted to the static charge.

Students describe the images seen in flat and convex mirrors.

Students investigate energy transfer by colliding marbles, explaining their observations, and what happens to the energy of the moving marble on impact.

For this practical task students investigate convection currents when tea leaves are placed into a beaker of water that is being heated. They are asked to make observations and to provide an explanation of what they have observed.

Task: read an article about releasing hand-reared kaka into a safe environment and answer questions about the research. Assessment focus: field investigations.

This task requires students to develop questions about their local geology and name possible information sources.

For this practical task students investigate and report on what they noticed about a model river and how different sized materials are moved by the water.

For this practical students make observations about dissolving, and plan and carry out an investigation to find out what makes sugar dissolve more quickly.

For this practical task students are assessed on their ability to observe changes that have occurred to 'popping' corn before and after it is heated. Drawings and written observations are required.

This practical task requires students to make observations of the changes that occur in five common foods as they are cooked.

For this practical task students record their observations as an egg is poached in water.

This practical task requires students to plan and carry out a fair test to find out which paper type will soak up water the best.

Students outline four ways of improving a given plan for an investigation to make it a fair test.
