Gather and interpret data resources

Students are provided with a narrative of two children who have gone back to the past at a time when dinosaurs existed. Students have a number of questions to answer during the narrative.

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

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

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

Students are required to write down some relevant questions about the Moon's surface that they would ask an astronaut who has just returned to the Earth from the Moon.

For this practical task students create a sundial by marking observations and recording the time for each hour, and answer questions about shadows and sundials.

For this practical students are required to investigate how the use of pulleys affects the effort force needed to raise a load. Students gather results, write a conclusion, and describe two situations in which a pulley system would be useful.

In this task students compare two photographs of a river with normal flow and a river in flood. They make inferences based on their observations.

Task: select a card to show how to control the variables of an investigation into the rolling distance of marbles on different surfaces. Assessment focus: controlling variables.

Task: Students match parts of statements about how Joan Wiffen worked like a scientist, and identify what skills or experiences helped her find fossils. Assessment focus: interpreting information about how scientists work.

Students complete tables of energy use.

Students describe what makes two boats move and change direction.

Task: Students answer questions about what will make mountain bike riders go faster. Assessment focus: Air resistance.

Students carry out a simple experiment to illustrate refraction. They then explain why this happened.

Students predict and investigate the way in which a concave and a convex lens distort the image of a pencil.

Students carry out a simple experiment with static electricity and then explain their findings.

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

Task: investigate reflection of light using a torch and mirror. Assessment focus: angle of reflection.

This practical assessment requires students to design and carry out tests on three properties of four different fabrics in order to find the most suitable fabric for the stated purpose.

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.

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

For this practical task students make observations about the effect of coloured lights on different coloured objects. Students then draw some conclusions about their findings.

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.

Task: Explain how a change in the cockle population has affected one or more organisms in a food web in the short and long term. Assessment focus: Sorting observations and inferences; reading food chains and; using a food web diagram to predict impact of change.

Task: Identify how features/adaptations of a starfish help it survive, and decide whether the amount of evidence from scientists' observations supports or does not support their theory/inference. Assessment focus: using observations as evidence to inform theories.
