Task: select a card to show how to control the variables of an investigation into the rolling distance of marbles on different surfaces. Assessment focus: controlling variables.
This practical task requires students to record temperatures of various areas in the school and to suggest reasons why some areas are warmer or cooler than others.
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: Explain how to use the magnet to remove a drawing pin out of a glass of water without putting the magnet in the glass, touching the glass with hands, or spilling the water. Assessment focus: using knowledge of magnetism to solve a problem.
Students investigate energy transfer by colliding marbles, explaining their observations, and what happens to the energy of the moving marble on impact.
Choose which toy vehicle will roll further, and explain why. The two vehicles are set up under different conditions (ramps at different slopes, rolling onto different surfaces at the bottom). Assessment focus: science explanations using ideas about forces and energy.
Explain what affects the distance travelled by toy cars, and why they eventually stop. Assessment focus: science explanations using ideas about forces and energy.
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.
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.
