Solubility lesson with questions and answers

IGCSE Edexcel Chemistry solubility curves and solubility practical. Solubility definition and units of solubility, with solubility exam questions. Lesson objectives: Define key terms relating to solubility, Define solubility and Investigate the solubility of a solid in water at a specific temperature. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question.

The breakdown of the slides is as follows:
Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see above)
Slide 3 – matching activity for the key terms linking to solubility, e.g. solvent, solute, solubility, etc.
Slides 4 – 5 – printable copies of slide 3 for students
Slide 6 – diagram introduction to practical
Slide 7 – method for practical (step-by-step)
Slide 8 – results grid where students will record their data
Slide 9 – introduction to solubility curves
Slide 10 - If you had 180 g of KNO3 at 80℃, it would look like the first photo. However, if you cool the solution down to 40℃, it would look like the second photo, as the mass of salt which cannot dissolve at the lower temperature crystallises out of solution
Slides 11 – 13 – series of worked examples of solubility curve problems. Answers animate on to the screen as you click (don’t worry!)
Slide 14 – data for students to draw their own solubility curve (graph paper not provided)
Slide 15 - WAGOLL
Slide 16 – ALT (Applied learning time). Questions that require students to interpret the solubility they have drawn to answer. If they were not able to draw it, print slide 15 for them and have them use it to answer the questions.
Slide 17 – Answers
Slide 18 – Exam question slide
Slide 19 – mark scheme
