Lesson details
Key learning points
- Choosing the correct equipment is crucial for obtaining accurate and reliable results.
- An upturned measuring cylinder is suitable for reactions producing large volumes of gas at moderate rates.
- Gas syringes are ideal for measuring small volumes of gas with high precision.
- The size of the measuring equipment should be close to the expected volume of gas produced.
- Light sensors can be used to measure the percentage of light transmitted through a reaction producing a precipitate.
Keywords
Rate of reaction - Rate of reaction is the speed with which a chemical reaction takes place, measured by the amount of a reactant used or amount of product formed in a given time.
Volume - Volume is how much 3D space matter occupies. It is usually measured in cm³.
Accurate - Accurate measurements are those that are close to the true value.
Precise - Precise measurements have very little spread from the mean value. They are values that lie close to each other.
Common misconception
Thinking that precise and accurate are the same thing.
It may help to draw a bullseye target board. Precise results will all be close to each other but may not be near the bullseye. Accurate results will be near the bullseye but may be more scattered if they are not precise.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
