Edexcel 9-1 Evaluation sheets for CORE practical - Cover sheets
OFSTED are very big on feedback from the teacher and the student and these can help to hit the boxes
Chemistry
Core practical descriptions:
Core practical 1: Investigating the composition of inks
Core practical 2: Investigating pH
Core practical 3: Preparation of copper sulfate
Core practical 4: Electrolysis
Core practical 5: Acid‐alkali titration SEPARATE SCIENCE
Core practical 6: Rates of reaction
Core practical 7: Identifying ions SEPARATE SCIENCE
Core practical 8: Combustion of alcohols SEPARATE SCIENCE
They cover RAG (red, amber green), during the experiment and before and after the experiment, teacher feedback. WWW = what went well, EBI = even better if and both self assessment and teacher assessment
I stick them in at the start of the lesson and review them at the end of the lesson/beginning of the next lesson. It gives me an idea where students are in terms of knowledge from the theory lessons, how their practical skills are coming on and their maths skills. It also gives a very good revision resource so students can decide what they need to work on and what the examiner wants during these core practical sessions.
Students really like them
Enjoy
