Edexcel 9-1 SEPARATE TRIPLE SCIENCE HIGHER Chemistry Calculations Revision LESSONS

CAN BE USED FOR ABOUT 8 LESSONS
OVER 187 SLIDES
ACTIVATE - SHOWING THE FORMULA AND HOW IT WORKS
DEMONSTRATE - ALLOWING STUDENTS TO COMPLETE THE QUESTIONS
AFL - CHECKING ANSWERS (ALL ANSWERS PRESENT)

Edexcel CC9 PART 1-3 Calculations involving masses for the new 9-1 GCSE

6-8 lessons depending on how good student are at the calculations
Mainly covering
TOPIC 1 KEY CONCEPTS OF CHEMISTRY PAPER 1 and PAPER 2- NEW for SEPTEMBER 2017
TOPIC 5 SEPARATE SCIENCE PAPER 1: QUANTITATIVE ANALYSIS
Touching on TOPIC 7 Bond energy calculations for the higher tier students

Powerpoint with over 187 slides including worked examples, questions for the students to complete and then the answers of the questions.
Some calculations include more than one method, to help stretch the brightest and support the lowest ability students.
There is a summary slide for each paper (Paper 1 and Paper 2- separate science/ triple science) and a calculations summary slide to show all the equations that students will need to know over the 2 separate science papers.

QUESTIONS ATTACHED TO ALLOW STUDENTS TO WORK INDEPENDENTLY OR AT THEIR OWN PACE (THEY ARE THE SAME QUESTIONS AS IN THE POWERPOINT - SO ALL ANSWERS ARE IN THE POWERPOINT) Can set as homework or use in a revision lesson.

Calculations include:
