What is a lattice and what are the different lattice structures? Diamond, graphite, graphene, fullerenes, carbon nanotubes, and silicon dioxide structures and bonding is included. What is the difference between structure and bonding? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 12 A level lesson for Edexcel International Unit 1 – WCH11, but it can also be used for all UK exam boards. 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 (which are best opened on Microsoft PowerPoint) 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 your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – Two hinge questions: What is a crystal? What is a lattice? (note this is a recap from the previous lesson on metallic bonding)
Slide 4 – Introduction to the four types of lattice structure (giant metallic, giant ionic, giant covalent and simple molecular)
Slides 5 – 6: Mini Whiteboard questions on giant ionic lattices and giant metallic lattices, with corresponding properties to match
Slides 7 - 12 : focus on diamond, graphite and graphene, with word fills to facilitate students’ note taking. All the properties of these allotropes is covered in detail, with clear diagrams
Slide 13 - learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest. Answers animate onto the screen when you click
Slide 14 - a link to a rap made by one of our teachers about diamond, graphite, and graphene. Encourage your students to sing along!
Slide 15 – Word fill activity on graphene, including the formation of carbon nanotubes and fullerenes from graphene
Slides 16 – 17: information on simple molecular lattices and a diagrammatic form of iodine to display iodine as a solid lattice
Slides 18 – 22: Explanation of the low melting and boiling points of simple molecular lattices
Slide 23 – difference between structure and bonding
Slides 24 – 27: Comparing and contrasting of silicon(IV) oxide and diamond
Slide 28 – extended response question for six marks: Compare and contrast the structure and bonding in diamond and silicon(IV) oxide
Slides 29 – 34: Exam questions with mark scheme answers (included with the purchase of this resource)
