PowerPoint that covers the following learning objectives: Define the mass of an object. Measure mass of an object using a mass balance. Includes questions, pictures, instructions and a practical in which the students have to use mass balances to measure the mass of up to 20 objects. There are questions that ask students to add masses of objects together, substract masses and work out the difference. The results table, questions and space for answers are on the worksheet. This is for a primary/early secondary class. If you could spare 5 minutes, please review this resource, to help my online presence grow! :)

PowerPoint that covers the following learning objectives: Measure the temperature of a substance. Plot a graph of temperature vs. time.
