1.1.3 - 4 The development of the atom (AQA GCSE Chemistry)

Spec 1.1.3 - 4 The development of the atom – Could be up to three hours of teaching

Lesson(s) preparation:

For making paper timelines: printed pictures on slide 18, textbooks, access to online information
For making model timelines: long balloons, glue, permanent markers, blutack,

Rationale:

If you choose to make models, ensure that the lesson doesn’t become about presentation or artwork, but more assimilation, summarisation and representation of information.

Suggested teaching:

Lesson 1 (slides 2-8)

Slides 4-8: A way for students to make some notes, but by thinking hard and applying information rather than just copying

Lesson 2 (slides 9-21)

Slide 11: Important information that students are required to learn. They should be aware of most, so is a recall activity.

Slides 14-20: This can be used to encourage students to build model or paper timelines to present information about the development of the model of the atom.

Lesson 3 (Slides 22-26)

Here there is a chance to compare the plum pudding model to the nuclear model.
