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.
Students use diagrams to answer questions about atoms, elements, compounds, and mixtures. They are then asked to use these words to describe the differences between diagrams.
Task: Complete a table to show how energy is transformed in eight objects and describe the energy transformations in two others. Assessment focus: energy transformation.
Students are asked to identify two impending signs of a volcanic eruption and to describe four geological events that are linked to volcanic eruptions.
Students are asked to explain how a stone from the top of a mountain could become sand on a beach. Students then identify the most likely way stones 'move' from the tops of mountains to the coast.
This resource requires students to process information on an earthquake. This entails calculating the distance that the recording stations are from an earthquake's epicentre, locating the epicentre, calculating the magnitude, and answering general questions on earthquakes.
This practical task has two parts. The first part of this practical requires students to observe the effects of different indicators on different substances. Students use these results to identify if some other substances are acid, alkali, or neutral.
This practical task consists of two parts. Students test various substances with hydrochloric acid, iodine solution, and universal indicator, and then complete a table with their observations. The second part requires students to identify four unknown solids using their tests and results from part one.
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 are provided with a graph of the heating curve for octane. Students use this to answer questions about state, temperatures, and changes of state.
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.
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.
