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: Students differentiate between simple observations and inferences, and between observations that require measurement and those that do not.
Assessment focus: observing scientifically.
For this practical task students investigate and report on what they noticed about a model river and how different sized materials are moved by the water.
Students use a diagram that shows a proposed site for a town that has a river running through it. Students identify where it would be best to collect drinking water, and how town planners could stop the town from flooding.
