In this practical task, students estimate, and then measure, the weight of two objects using a number of multi-link cubes, a balance scale and weights.
Task: Measure 100mL of water into three different pieces of equipment. Weigh the result and calculate the precision of using that piece of equipment. Assessment focus: measuring and evaluating the accuracy of equipment.
This practical task requires students to lift a 1 kg weight and then estimate whether a range of everyday objects weigh less than, about the same as, or more than 1 kilogram.
