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 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: 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.

Students describe the images seen in flat and convex mirrors.

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 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 investigates the effect of temperature on the rate at which corn pops. Students collect data and make a conclusion.

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

This practical task assesses students' ability to record and graph data, and draw conclusions, as they conduct an experiment on the rate at which an ice cube melts in different temperatures.

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.

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.

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.

Students are given some solids and liquids for this practical task. They plan how they would find out which liquids are solvents for any given solid, carry out the task, and write a conclusion.

Students complete a plant record for a tree by making observations.

Students are provided with a fact file on the tuatara. Students answer four questions that are based on information contained in the fact file.

For this NEMP task students show their understanding of the life cycle, functions and parts of a tree.

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.
