KS3 Science lesson on groups, periods and trends (Activate C2.1). Editable Year 7 PowerPoint with retrieval starter and answers.
About this lesson
Lesson 4 of 9 in the Year 7 Periodic Table unit (Activate C2.1). Pupils state the group and period of an element, describe a trend using data, and predict a missing value from a pattern.
Built into every lesson
Retrieval starter: five questions check the prior knowledge pupils need for the lesson (answers in the notes)
A concrete, surprising hook to get pupils talking
Learning objectives pupils can act on, each with a ‘Show it’ task
Formative assessment throughout: checks, hinge question, plenary and exit ticket
Common misconceptions targeted: a hidden teacher slide and hinge questions from documented KS3 misconceptions
Command words always come with a sentence starter or writing frame
Four Tier 3 key words, with pronunciation and warnings about everyday meanings
Booklet task slides, each followed by an expected-answers slide, so all the answers are in this PowerPoint
Written for KS3 reading levels: one short idea per bullet
Fully editable PowerPoint (the lesson only: the printable workbook is a separate, paid resource)
