AC9S8U07 Year 8 Science

Content descriptor compare physical and chemical changes and identify indicators of energy change in chemical reactions

Elaborations

• • Elaboration performing simple chemical reactions to identify the indicators of chemical change such as gas production, solid production, colour change and temperature change
• • Elaboration analysing and interpreting data on the properties of substances before and after the substances interact to determine if a chemical or physical change has occurred
• • Elaboration investigating and identifying energy changes in different chemical reactions such as differences in temperature
• • Elaboration examining how the physical and chemical properties of a substance will affect its production or use
• • Elaboration discussing where indicators of chemical change are used for identifying the presence of particular substances, such as in soil, water and medical testing kits
