Worksheet (age 16+ - A level, BTEC) with theory and full answers, covering the tricky topic of the Archimedes principle. Included is a description of calculating density, which some students find difficult, particularly for shapes such as cylinders and spheres. This product focusses on water-based exam questions, a subsequent worksheet will consider problems with air balloons etc. The detailed answers help not only teachers but students to understand the logic of the problems and to gain a feel for the Maths involved.

A full suite of lesson material (slides, worksheets, handout and answers) on SI units, suitable for all Science students age 16+. May be suitable for bright classes at GCSE. Learning objectives are to review powers of ten, then to learn about prefixes and standard form in all Sciences. This material is high quality and is designed to make sure that students develop their numeracy skills beyond GCSE/A level to prepare them for university, where high numeracy is essential.

Age 16+ Physics students Full worksheet of 10 questions with answers covering the topics of: - drift velocity - potential difference, charge and work/energy A level standard, suitable for BTEC as well

Physics worksheet of 10 questions with full, detailed answers aimed at Age 16+ (A Level standard) Questions on general density calculation, then some based on first calculating the volume of shapes (rectangular box, cylinder, sphere), formulated on engineering metal samples. Good contextual worksheet which will cement the concept of density by constant reference to problems faced with density in engineering projects.

This resource contains slides, worksheets and answers on the topic of Scalars and Vectors in Physics. It would suit A level students but could be used to introduce GCSE students to the topic. There are many worked examples in the slides plus plenty of problems and answers in the worksheet materials. The aim was to give students a deeper understanding than with simpler resources, as this topic is central to university courses, where vector reasoning and manipulation is an essential skill.

For Science students age 16+. A detailed presentation, worksheet and full answer sheets to introduce the topic of converting complex units, to follow on from the first lesson on basic SI units. To prepare students for University and industry, it is critical for them to practise complex unit conversion, as this practice will improve their exam results and increase their chances of gaining mastery over units. A total mastery of units is essential to work in industry, all engineers do this all day every day and we rarely have space in curricula to give them this practice. Please comment on this and the previous lesson, which will help me to improve my lessons. Thanks

Chemistry workbook for age 16+ on Mass Spectrometry. Learning objectives are operation, description of the stages and calculation of relative atomic mass from isotope abundance data. There are 3 full exercise with answers to support the 3 learning objectives. Exercise 1 asks students to reorganise a list of steps of the operational steps of the MS, which forces them to think about each stage and to re-write the basics of each step to enhance their understanding. There are notes and a labelled diagram at the front of the workbook to help them with this exercise. Exercise 2 asks questions on the details of the operational steps, chosen from typical exam questions. Exercise 3 on calculation of relative atomic mass gives students plenty of practice with their calculators, they generally find this difficult so this exercise was designed to address this need. The whole workbook should take around 2 hours, but this may be less for more-able students. Generally this topic is easy marks for students but they rarely take it seriously, so I designed the workbook for my own students to get them to focus on it and secure these easy marks, which they have !!
