For this practical task students follow a plan to determine the effects of a weak acid on different building materials. Students need to put their results into a table and write a conclusion.
Students compare drawings of a healthy and unhealthy plant and decide which quantitative and/or qualitative data distinguishes them. They draw conclusions from the data. This is a mathematics/science resource.
Task: Use written text about farming's contribution to climate change to complete a flow chart, and answer questions about the two texts. Assessment focus: interpreting, using, and comparing different types of text.
Task: Demonstrate understanding of the pupil reflex of the eye, and apply this to answering questions about sunglasses safety. Extension questions probe understanding of who decides on and applies safety standards. Assessment focus: effect of UV light on the eyes and how it can be mediated by simple sunglasses technology.
Students first do the science activity Throwing Balloons - investigation (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.
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.
Students formulate questions about glaciers and climate change to show awareness that informed opinions are based on inter-related aspects of evidence rather than individual instances.
Task: Select the most suitable thermometer to use for different purposes and answer two questions about scale. Assessment focus: making measurement decisions.
Task: Identify from an experiment the preferred living conditions of slaters, and use a fact file to suggest reasons why. Assessment focus: interpreting results of an investigation.
Explain what affects the distance travelled by toy cars, and why they eventually stop. Assessment focus: science explanations using ideas about forces and energy.
This practical task requires students to first plan how they could find out which liquid flows the best. Then they carry out their plan, record their results, and write a conclusion.
Students classify six common substances as either a solid, liquid, or a gas. Students then group these substances into elements, mixtures, or compounds.
Students are given a graph that shows how many days it took for bread placed in different areas to grow mould. Students use this graph to answer three short questions.
