Task: Predict, observe and explain what will happen when a balloon containing another balloon filled with water is thrown. Assessment focus: making and explaining predictions and observations.

Task: Predict, observe and explain what will happen when a balloon containing another balloon filled with water is thrown. Assessment focus: making and explaining predictions and observations.

This practical task requires students to use methods of separation to separate a mixture of salt, sand, and iron filings. Students explain how they did this and the property of the substance that they used.

Task: Create, use and identify ‘rules’ based on observable and/or measurable physical properties of common plastics. Assessment focus: classifying & identifying.

For this practical task students write a plan to find out if a microwave has a 'hot spot'. Students carry out their plan, collect, and interpret results.

Task: Answer two questions about melting and two questions about dissolving. Assessment focus: describe and explain melting and dissolving.

Task: Match insects to their adaptations for protection against enemies, and infer two ways stick insects are adapted for their protection against predators. Assessment focus: using observations to make suggestions about survival methods.

Choose which toy vehicle will roll further, and explain why. The two vehicles are set up under different conditions (ramps at different slopes, rolling onto different surfaces at the bottom). Assessment focus: science explanations using ideas about forces and energy.

Plan an investigation to find out which of two students' predictions is correct, and identify how to recognise what a result would look like. Assessment focus: identifying what to measure or compare to answer a science question.

Task: Students fill in a chart to select the best material for making 6 objects, and give reasons for their answers. Assessment focus: properties of materials related to use.

Describe methods for speeding up and slowing down melting of an ice cube using one of three provided objects, and explain why the methods would work. Assessment focus: planning an investigation.

Task: Select which state of water applies to a list of places where water can be found. Assessment focus: states of water.

Students first do the science activity Throwing Balloons 2 (PW2548) where they predict, observe, and explain what will happen when a balloon containing another balloon filled with water is thrown. Then the students do this writing task where they describe the balloon and what happened when it was thrown, and explain why they think it moved the way it did. Six annotated exemplars of student scripts (writing) are included under the "Working with Students" tab.

Explain what affects the distance travelled by toy cars, and why they eventually stop. Assessment focus: science explanations using ideas about forces and energy.

Students categorise statements according to whether they are evidence or inferences. They make inferences about moa, supporting them with evidence. Assessment focus: thinking in scientific ways.

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 explain the terms physical and chemical change. Then they read a passage of text and identify the six changes that have occurred and state if each change is a physical or a chemical change.

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.

Task: Use pictures to identify special features of various fish and make predictions as to likely habitats based on these features. Assessment focus: purpose of adaptation in fish.

Task: Read information and compare the special features that influence the chances of survival of black robins and fantails. Assessment focus: interpreting text to identify risk factors for survival.

Task: Make observations from a photograph, identify potential environmental problems giving reasons, decide which problem is the most important, and give reasons for the choice. Assessment focus: (1) observation, and (2) identifying and prioritising cause and effect relationships.
