Mole calculations with Avogadro constant, calculating the number of particles, number of moles, relative molecular mass and molar mass. Include moles exam style questions. 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 – Introduction to the definition of a mole
Slide 4 – Example of a mole using a high-quality photo of ‘one mole’ of locusts
Slide 5 – Definition of Avogadro’s constant
Slide 6 – Mini plenary/learning pit stop. Three questions of increasing difficulty to check students’ understanding thus far. Answers animate onto the screen.
Slide 7 – Introduction to the concept of molar mass
Slide 8 – Example of molar mass being calculated using ethene
Slide 9 – number of moles = mass/molar mass (presented as equation and formula triangle, depending on mathematical ability of students)
Slides 10 – 12: worked examples of increasing difficulty, all with working out and answers that animate onto the screen
Slide 13 - Mini plenary/learning pit stop. Three questions of increasing difficulty to check students’ understanding thus far. Answers animate onto the screen.
Slide 14 - number of particles = number of moles x Avogadro constant (presented as equation and formula triangle, depending on mathematical ability of students)
Slide 15 – Worked example with new formula for finding number of particles
Slide 16 – Final mini plenary/learning pit stop. Three questions of increasing difficulty to check students’ understanding thus far. Answers animate onto the screen.
Slides 17 – 20: Exam questions with mark scheme answers (all included with this resource)
