Chromatography quiz

(0)
A traffic light quiz on paper chromatography, students hold up the relevant coloured card to answer the questions in the quiz. Suitable for the new 2018 Chemistry GCSE. I use it as a plenary at the end of the lesson.
Paper Chromatography
polarity24polarity24

Paper Chromatography

(0)
A GCSE Chemistry worksheet on Paper Chromatography. The worksheet is differentiated with exam questions targeting grades 1-3, 4-6 and 7-9. There’s questions on mobile and stationary phases, food additives, calculation of Rf values etc. The more challenging questions require students to think in more depth about the physical processes involved in the separation, explaining how separation occurs, how we use chromatography to identify additives etc. Answers are included.

Calculating pH - Cooperative learning activity
polarity24polarity24

Calculating pH - Cooperative learning activity

(0)
A 20 minute group work activity on calculating pH. Split class into 4 groups, each group containing all levels of ability (so that the brighter students can help the lower ability.) Each group given one of 4 questions to solve. Teacher circulates giving hints where needed. Once each group has solved their question (allow 5-10 mins). students then return to their original seat and have to teach the solution to their question to their colleague. A great way to encourage group work and has always been graded as an outstanding lesson when observed by leadership. Answers are included and a 5th question included at the end of the activity to illustrate progress.
