Investigating in science resources

Task: Select the most suitable thermometer to use for different purposes and answer two questions about scale. Assessment focus: making measurements decisions.

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

Students compare drawings of a healthy and unhealthy plant and decide which quantitative and/or qualitative data distinguishes them. This is a mathematics/science resource.

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: Select cards to show how to control the variables of an investigation into the rolling distance of marbles on different surfaces. Assessment focus: controlling variables.

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.

Task: Use displacement to measure volume. Assessment focus: displacement.

For this practical task students investigate convection currents when tea leaves are placed into a beaker of water that is being heated. They are asked to make observations and to provide an explanation of what they have observed.

This practical task is about heat absorption. From a given list students choose the equipment they would use to heat cold tap water as much as possible. Students complete the investigation, explain why each piece of equipment was selected, and record their results.

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.

For this practical task students complete a table of observations on nine common materials. Students then use their results to group the materials according to similar properties.

This practical task requires students to sort some common items from hardest to softest. Students then explain a test that they used to help determine this.

In this practical task students investigate the effect of temperature on viscosity. Students describe and explain what has happened.

Students use information on the properties of five different drinks in order to place them correctly into a key.
