Students are provided with a diagram of a bag used in solar showers. They answer questions about this bag relating to heat absorption, heat transfer, and radiation.
Students indicate for each of six different variables those that need to be kept the same for an investigation about dissolving different types of sugar.
Students are provided with a graph of the heating curve for octane. Students use this to answer questions about state, temperatures, and changes of state.
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.
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.
Students look at two diagrams. The first shows iron nails in test tubes with boiled water or tap water, the second shows iron nails with moisture either present or absent. Students answer five questions about these investigations.
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.
Students are given an outline of an investigation on heat loss from two different shaped objects (a cube and a sphere). They answer questions on variable control, repeat trialling, and they then graph data from this investigation.
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.
Students are given an outline of an investigation on metal corrosion and a graph of some results. Students' ability to interpret the graph and knowledge of fair testing is assessed via short answer questions.
Students are given a partially completed table which details materials which are used as either conductors or insulators of heat. Students complete the table by indicating whether the materials conduct or insulate heat or give an example of its use.
The results of three different crosses between long-haired and short-haired rabbits have been provided. Students state, with a reason which characteristic is dominant and complete a punnet square for one of the crosses.
Decide whether the photographed animals are reptiles or not, and justify responses. (A fact file giving the features of reptiles is given.) Answer a question about why scientists have an agreed way of grouping living things. Assessment focus: using science-based classifications.
