Lesson details
Key learning points
- At a given temperature, there is a limit to how much solute can dissolve in a solvent.
- Solutes may become insoluble as a solution cools.
- Lines of best fit can be used to predict unknowns values if one variable is known.
- Data from multiple investigations can be plotted on the same graph for ease of comparison.
Keywords
Saturated solution - A saturated solution is one in which no more solute can dissolve in the solvent at a given temperature.
Solubility - Solubility refers to how well a solute is able to dissolve in a solvent to create a solution.
Line of best fit - A line that depicts the trend of scattered data plots on a graph.
Common misconception
Pupils are reluctant/struggle to plot multiple sets of data on one graph.
Fold the table of results so pupils are only looking at one set of data at a time when plotting. Use different plot symbols/colours too.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
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.
