This GCSE Physics PowerPoint presentation provides a comprehensive guide to the required practical on density, covering regular solids, irregular solids, and liquids. Designed for AQA GCSE Physics, this resource helps students develop essential practical skills by measuring mass and volume to calculate density using the equation: density = mass / volume.
The lesson begins with a starter activity introducing density calculations and asking students to predict whether objects will float or sink based on their densities. It then provides clear explanations and step-by-step methods for measuring density using different techniques.
For regular solids, students will learn how to determine volume by measuring length, width, and height and using the formula for volume. A table of example data for materials like aluminium, brass, and wood is included to guide students in calculating density.
For irregular solids, the lesson explains how to measure volume using water displacement in a measuring cylinder or a Eureka (displacement) can, following Archimedes’ Principle. The method is demonstrated with sample data for objects such as a rock and a plastic toy, helping students understand how displaced water equals the object’s volume.
For liquids, students will learn how to determine mass using a mass balance and measure volume using a measuring cylinder. The lesson provides example calculations, highlighting the importance of subtracting the mass of the empty container to find the liquid’s actual mass.
To consolidate learning, the PowerPoint includes structured practice activities, review questions, and exam-style tasks that assess students’ ability to apply the density formula and analyze experimental errors. The fully editable PowerPoint (.pptx) allows teachers to customize content for their lessons, making it a valuable resource for classroom instruction and revision.
