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.

This practical task requires students to make observations of the changes that occur in five common foods as they are cooked.

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.

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.

For this practical task students are given a variety of objects which they are required to make observations on by using their senses.

For this practical task students use their knowledge about the properties of gases to explain their observations when they blow up a balloon that is inside a bottle and a balloon that is not inside a bottle.

Students decide on the variables that will make an experiment about boiling water a fair test. Assessment focus: Recognising multiple variables.

Students use a table of information to answer questions about descriptions of different substances.

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.

Task: Identify the variables for testing how fresh water and salt water affect rusting. Assessment focus: planning a fair test.

Students explain the mistake in each of six sentences about elements, compounds or mixtures.

Students use a table on solubility/insolubility of 16 compounds to determine the validity of four statements and justify with evidence from the table.

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.

Information on particle size and boiling point is provided for three alcohols. Students use this to place these substances in order of particle size and increasing boiling point.

The liquid range for four common substances has been provided. Students use this to answer questions about melting point, boiling point, and state.

Students are asked one multiple-choice and one short answer question about fair testing.

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.

Task: Measure 100mL of water into three different pieces of equipment. Weigh the result and calculate the precision of using that piece of equipment. Assessment focus: measuring and evaluating the accuracy of equipment.

Students use a table of information on melting points and boiling points of six different substances to answer questions about states of matter.

This practical task investigates the effect of temperature on the rate at which corn pops. Students collect data and make a conclusion.

This practical task assesses students' ability to record and graph data, and draw conclusions, as they conduct an experiment on the rate at which an ice cube melts in different temperatures.

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 outline a test they could do to show if a substance is a metal or not.

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 draw a circle around those objects that are hard.
