Temperature changes: practical workbook
GCSE Chemistry required practical 4
Everything for the temperature changes required practical in one printable workbook: the method, a blank table, a full simulated data set to analyse, exam questions and answers.
What is inside
- The practical: aim, variables, apparatus and the method in plain steps
- Risk assessment to complete
- Blank results table with the right headings, drawn before you start
- A seeded data set: a full set of classroom-realistic results to process
- Graph paper page
- Analysis questions on the data set, including unseen-data questions
- A 6-mark method question
- Answers at the back: the completed table, the graph, worked answers and mark points
The practical: Investigate how the volume of sodium hydroxide solution added to hydrochloric acid affects the temperature of the mixture, and use the graph to find the volume that neutralises the acid.
Work through it the way it is done in class: plan and assess the risks, draw the table first, then process a complete data set from a simulated class run, with repeats and the kind of anomaly real results contain. Plot the graph on the graph paper provided, answer exam-style questions on the same numbers and finish with a 6-mark method question.
Answers at the back show the completed table, the graph with its line, worked calculations and the marking points, so a student can check their own work. The data come from the Study Hack Lab model; the seed printed on every page makes them again exactly.
