Rate of Reaction (Surface Area) - SEN/LAP

This worksheet has been made for students doing entry level chemistry in an SEN school. 1 lesson practical, 1 lesson write up.

The worksheet has a picture of the practical and is investigating different sized marble chips and the reaction with hydrochloric acid.

Students complete 3 sets of results, writing the change in mass every 15 seconds for 3 minutes. It is based on chem guide UK’s video on how surface area affects rate of reaction.

Worksheet includes:
Gapfill activity method completion
Prediction
Results table - small, medium and large marble chips
Graph analysis gapfill - teacher to show students how to draw a line graph
What did students change, measure, keep the same questions
What could they improve - e.g. were they accurate
Conclusions
Whether this matched the prediction
