Hi, I'm Tom

Key Stage 2: Since 2017 I have been working as a science and maths teacher in a specialist SEND school with primary school-aged children with a wide range of learning difficulties, including ADHD, Asperger's. dyslexia, dyspraxia and dyscalculia. This has involved planning engaging and fun practical science experiments in line with the KS2 curriculum, and devising interactive maths lessons to help the students grasp basic numerical concepts . - Case study: "I", aged 9, with ADHD, dyscalculia, Asperger's. Science: "I" had a keen interest in the 'messy' side of Science, so our experiments were generally Chemistry-oriented, involving chemical reactions that invariably produced interesting substances, explosions or slime. He learned how to write up observations in his exercise book independently, and further explore the 'theory' behind our experiments. Maths: "I" struggled with counting an...Learn more

Chemistry βš›οΈ
G is a colourless crystalline solid which reacts with dilute nitric acid to give a colourless solution, H, and a colourless, odourless gas, I, which turns limewater milky. G has a lilac flame colour. Identify G, H and I (I’m aware that I is CO2)?
Verified
