Year 10 Science
Unit Name: Chemical Sciences
Length: 9 weeks
Content Descriptions:
 The atomic structure and properties of elements are used to organise them in the Periodic Table
(ACSSU186)

lives, including generating new career opportunities (ACSHE195)
 The values and needs of contemporary society can influence the focus of scientific research
(ACSHE230)
