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.
Students are asked to identify a solid, liquid, and a gas. They are also asked to write down two things that are generally true for each of these three states of matter.
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 need to interpret data about travel time to school and common after-school activities and identify which statement is true from a list of given statements.
