Spec 1.2.5 The alkali metals (Two hours suggested teaching time)

Lesson preparation:

[Demonstration] The physical properties and reactions of the alkali metals
Could print the table on slide 11
Could print the exam questions on slide 21

Suggested teaching:

Lesson 1:

Slides 2-4: Retrieval practice starter (slide 4 is an optional and differentiated alternative starter).

Slide 5-6: Recap of forming ions with a focus on the group 1 elements.

Slides 7-8: (Hidden) Alternative recap, potentially for lower ability students on electron configurations.

Slide 9-11: Here you can demonstrate the properties and reactions of the alkali metals. If materials are unavailable, students could compare the animations of the reactions on slide 10. There is a table on slide 11 to record their observations.

Lesson 2:

Slides 12-14: Retrieval practice starter (slide 4 is an optional and differentiated alternative starter).

Slides 15-16: A recap of the observations and reactions of the alkali metals.

Slides 17-20: Explaining the reactivity of the alkali metals, with a selection of differentiated slides to help.

Slides 21-22: Practice exam style questions.
