Using illustrations from five different beech trees and a key, students are asked to identify which type of beech tree each leaf comes from.

Students use a key to classify and describe a number of the illustrated insects and spiders.

Students answer questions about how a road moves after an earthquake.

This practical task requires students to follow an experimental design that investigates various forms of insulation. They are required to gather results, make a conclusion, and identify the variables.

Task: Answer two questions about setting up a fair test and another about insulating houses. Assessment focus: controlling variables.

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

This practical task requires students to use a plastic comb and wool to generate static electricity. Students investigate different materials to find those that are attracted to the static charge.

Task: Make a sound gun and use it to investigate what happens to a candle when the end of the sound gun is tapped. Assessment focus: sound waves.

Task: Students answer questions about what will make mountain bike riders go faster. Assessment focus: Air resistance.

Students carry out and make observations about water in a straw, and suction. Students are then required to explain their observations.

Students describe the images seen in flat and convex mirrors.

Explain what affects the distance travelled by toy cars, and why they eventually stop. Assessment focus: science explanations using ideas about forces and energy.

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.

Task: read an article about releasing hand-reared kaka into a safe environment and answer questions about the research. Assessment focus: field investigations.

Students are asked to explain why the Southern Cross appears not to be in the same place in the night sky that it was a few months previously.

This task requires students to develop questions about their local geology and name possible information sources.

For this practical task students complete a table of observations for the following substances: vinegar, baking soda, and vinegar and baking soda mixed together.

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.

For this practical task students plan and carry out a fair test to determine which of four different cups will keep water the hottest over 10 minutes. Students are also required to graph their results and write a conclusion.

For this practical students use provided definitions to classify 12 objects as either transparent, translucent, or opaque.

Task: Predict, Observe, Explain, (POE) activity observing what happens to air in a balloon when it is heated. Assessment focus: behaviour of gases when heated and cooled.

Task: Describe what happens to ice in a glass of water, giving reasons, and explain where water forming on the outside of the glass comes from. Assessment focus: changes of state.

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.

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

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.
