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

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.

In this NEMP task students conduct a test to identify whether a number of substances are acid, base or neutral. They also answer a question about neutralising. Assessment focus: testing acid or base.

Task: Use understandings about heat energy and insulation to describe how adaptations help Emperor penguins survive in Antarctica. Assessment focus: adaptations for keeping warm in cold conditions.

For this practical task students make a prediction about which lot of ice will melt first. Then students record their observations and explain why one lot of ice melted faster than the other.

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

Students explain the terms physical and chemical change. Then they read a passage of text and identify the six changes that have occurred and state if each change is a physical or a chemical change.

A description of two 'reactions' with household chemicals is outlined. For each students identify if the reaction is chemical or physical and provide an explanation for their answer.

This practical task requires students to make observations and draw diagrams about diffusion that occurs when food colouring is added to water.

Using provided information students answer three multiple-choice questions about numbers of atoms, elements, molecules and compounds.

Students select the correct written definition of the words element, compound, and mixture.

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.

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

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.

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

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

This practical assessment requires students to design and carry out tests on three properties of four different fabrics in order to find the most suitable fabric for the stated purpose.

This practical task requires students to use methods of separation to separate a mixture of salt, sand, and iron filings. Students explain how they did this and the property of the substance that they used.

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 evaluate a fair test about whether salt or sugar solution dissolves faster.

Select the correct pair to set up a fair test. Assessment focus: controlling variables.

Task: Students fill in a chart to select the best material for making 6 objects, and give reasons for their answers. Assessment focus: properties of materials related to use.

Students are given an outline of an investigation on metal corrosion and a graph of some results. Students' ability to interpret the graph and knowledge of fair testing is assessed via short answer questions.

Students identify which substances undergo a permanent change when they are mixed together.
