Secondary | Science | Required Practicals Lab Books – CollinsIt is important in this core practical to use appropriate apparatus to make and record a range of measurements accurately, including time, temperature and volume. This includes the safe use of apparatus, and monitoring chemical changes. This outlines one way to carry out the practical. Eye protection must be worn. To investigate the effect of changing the temperature on the rate of a reaction. Sodium thiosulfate solution reacts with dilute hydrochloric acid:.

More details on my research on intergrated instructions here. I have produced these as there will be many teachers who are using these practicals as a first port of call. However, as many have pointed out over the years, there is no requirement to use the particular practicals AQA have published. Indeed, AQA now make this very clear on the front page of their handbook:. Please note: it is the Apparatus and techniques requirements which are compulsory and must be fulfilled. Teachers are encouraged to adapt or develop activities, resources and contexts to suit their equipment and to provide the appropriate level of engagement and challenge for their own students.
Using a different measuring cylinder, C5. This should be an investigation involving developing a hypothesis. C4, add 10 cm 3 of dilute hydrochloric acid to the conical flask? OCR A and B practical activity groups?
