Observing Water Usage at Home
This weeklong investigation has students record their water meter readings from their homes every day for a week and then analyse those findings, creating charts and graphs and comparing it to the WHO’s recommended 50L/person. It is a great way of developing crucial investigation skills before their assessment.
This worksheet is a part of a larger unit designed for Year 6 that helps students develop their statistical investigation skills by walking them through the necessary stages to plan, conduct and analyse a statistical investigation and then communicate their findings.

Learning goals
- We are learning to pose questions, collect and interpret categorical or numerical data by observation or survey.
- We are learning to interpret and compare data displays, including side-by-side column graphs, tables and diagrams for two categories (e.g. age, height) and compare the usefulness of each display for data interpretation.
