Having taught GCSE and A level chemistry for 6 years and being an examiner I have developed a solid understanding of what makes a lesson outstanding and seek to share this with other teachers.
This is is a lesson for GCSE chemistry that matches the AQA new 2016 specification section 4.1 - atomic structure and the periodic table. The lesson begins with a fun film characters starter. There is then a discussion on how elements are made in supernovae. Students then consider rules for naming compounds and how to write formulae. They then then write the formulae for 12 substances. The challenge is to write empirical formulae. The lesson concludes with a consideration of how some of the chemicals are harmful to fish such as Nemo. Titanium dioxide in suntan cream causes water and oxygen in seawater to react to form hydrogen peroxide that is toixc to fish. Answers are included. Please rate this resource and leave feedback.
