Key questions for year 12/year 13 on Mass Spectrometry. Answer key included. The topic of the questions is molecular mass spectrometry and assumes some prior knowledge on atomic mass spectrometry and isotopes. There are 10 questions, which are designed to test knowledge and understanding. They could be used as a homework task pre-lesson as part of 'flip' learning, or as an independent or group task, using text books/online research to answer them.

Year 13 lesson on Transition Metal complexes (based on AQA syllabus). PowerPoint and worksheet included. Print out last 3 slides to hand out examples of TM complexes to students. LOs: To define key terms in relation to complex ion formation. To describe how the size of ligands affects the shape of complex ions. To explain how ligand charge determines the charge on a complex ion. 1. Do Now: Recap on transition metals 2. Student Activity: Think, pair, share - what does TM complex diagram show? 3. Student Activity: Students come to their own definitions of 'ligand' and 'coordination number' 4. Exposition: Monodentate, bidentate, tridentate terms introduced 5. Mini-plenary: Checkpoint activity asking for ligand, coordination number and shape for 3 new complexes 6. Student Activity: Students draw out bidentate ligand and answer questions 7. Exposition: Introduce and discuss various multi dentate ligands, perhaps introducing the term 'chelate' 8. Exposition: Explaining shapes of complexes with regard to the size of a ligand 9. Exposition: How to calculate total charges on complex ions 10. Independent Task: Students complete worksheet on TM complexes 11. Plenary: Recap of all new terms learnt, using 3 new TM complexes 12. Extension Task: Drawing TM complexes For more resources check out my shop: https://www.tes.com/teaching-resources/shop/alexpce If you liked this resource, please write a review! :)

Worksheet on the properties and formation of sedimentary rocks, and in comparison to igneous rocks.

For a lower set year 8 class. A highly scaffolded worksheet teaching students how to use the density formula to calculate densities of various solids. A cloze exercise testing understanding of key concepts about density.

LOs: To make predictions about whether an object will sink or float. To define density and relate it to the particle model. To use the equation to calculate the densities of different objects. Aimed at a lower set year 8 class. A higher ability class will probably require more. Density of solids and liquids PowerPoint. Includes heavily scaffolded worksheet on density calculations and a cloze exercise. Mini-plenary using mini-whiteboards or similar. Demonstration of density using water and a range of different objects.
