Atoms and Molecules

Work done in this Nuffield 13 - 16 module followed from the unit called ‘Particles’ and was intended to lead to an understanding of the ways in which some properties of materials can be explained in terms of the type and arrangement of their atomic and molecular building blocks. Giant structures were mentioned, but were considered more carefully in later units, such as Metals.

This B unit provided enough material for six double periods in the third year of secondary school (year nine). The teachers’ guide included four worksheets to supplement the students’ booklet.

1. Sorting particles according to size
2. Mystery solved by 'bumpy' particles
3. Particles sorted into atoms and molecules
4. Putting the picture to work
5. Another way to detect atoms
6. Sulphur grows to a giant molecule
