UNIT OVERVIEW

This unit builds the practical skills you need for your matric year. Before you tackle experiments on momentum, organic chemistry, or electrochemistry, you must know how to plan investigations, control variables, record data, and write scientific reports.

These skills matter beyond school. Medical researchers, water quality testers, forensic scientists, and engineers all use the same methods you will learn here.

In this unit, you will learn to:

• Plan and conduct controlled investigations
• Identify independent, dependent, and controlled variables
• Write clear, testable hypotheses
• Record data in proper tables
• Process and analyse data using graphs and calculations
• Draw valid conclusions and evaluate reliability
• Write scientific reports in the correct format
• Follow laboratory safety rules
