A differentiated worksheet to reinforce basic concepts around significant figures and standard form/scientific notation. The worksheet consists of three sections: Part 1 asks students to identify the number of significant figures in a given number; Part 2 requires students to give the answers to basic calculations using the correct number of significant figures; and Part 3 has students practice writing numbers in standard form. Students are asked to complete a minimum number of questions in each section, and each question has been designated as Level 1 (Easy), Level 2 (Medium) or Level 3 (Challenging). This resource complements my lesson on Standard Form and Significant Figures. Originally designed to support the Edexcel 9-1 GCSE specification (outcome 1.4), the worksheet would be suitable for use with any curriculum. It could be used as part of an introductory lesson on these concepts, or as a revision resource. Included is the worksheet in PDF, Word and Pages format, along with an answer key in PDF format.

Assignment sheet and sample mark scheme for a research project on the effects of smoking tobacco on the respiratory system. Students are asked to conduct research into chemicals found in tobacco smoke and the effects of three specified chemicals. They are then given the freedom to choose how they present their research, with the guideline that it should be structured as an informational advertisement (suggestions for possible formats are given). Originally designed to support the KS3 Exploring Science program, this project would fit into any National Curriculum specification. It could also work in a PSHE or other health education program. Includes the assignment sheet in PDF, Word and Pages format, and a PDF of the mark scheme I use, formatted 2-up on a page for ease of copying.
