KS3 ~ Year 8 ~ Solutions

This lesson is designed for the KS3 Year 8 Science course, specifically the C2 1.3 unit on ‘Separation Techniques.

More Biology, Chemistry and Physics resources can be found in my TES Shop: https://www.tes.com/teaching-resources/shop/SWiftScience

The lesson begins with a description of a solution, students can make a note of this in their books and then ‘Think > Pair > Share’ their ideas about examples of solutions they know. After a short discussion in pairs and as a class, some example answers are revealed to students.

Next, students are introduced to the key terms - solute, solvent and solution - given the example of salt being dissolved in water to produce a saltwater solution. The process of dissolving is explained using particle theory, using a particle diagram to help demonstrate the concept. Students will then be asked to come up with a role-play to demonstrate the process of dissolving, some groups can show this to the rest of the class.

Students will now complete a fill-in-the-blank worksheet to assess their knowledge of what they have learned so far this lesson, this can be marked and corrected using the mark scheme provided.

Lastly, students will be shown how to work out the total mass/volume of a solution given the mass/volume of the solute and solvent. Students will then work through a set of problems, the answers to which are included in the PowerPoint so students can self-assess their work using the mark scheme provided.

The plenary task requires students to write a twitter message to summarise what they have learned this lesson, including #keywords.

All resources are included at the end of the presentation, thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated
