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: Identify direction of currents and explain reason for pattern. Assessment focus: convection patterns.

Students answer a multi choice question and draw and explain their understandings about heat convection in a hot water cylinder. Assessment focus: Using science ideas to explain heat convection.
