For this practical task students investigate and report on what they noticed about a model river and how different sized materials are moved by the water.
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.
For this practical students make observations about dissolving, and plan and carry out an investigation to find out what makes sugar dissolve more quickly.
From a diagram of an experimental set up, students answer questions based on fair testing principles. Questions cover the control of variables, and measurement of results.
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.
This practical task requires students to describe to a partner their observations about an ice cube melting. Students then develop questions about what they observe.
For this practical task students complete a table of observations for the following substances: vinegar, baking soda, and vinegar and baking soda mixed together.
For this practical task students follow a plan to determine the best temperature for the reaction of rennet with milk. Students need to make observations and write a report on their findings.
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.
Students read some information about testing the absorbency of different papers. They outline two features that need to be kept the same if the tests were to be fair.
