Students investigate a range of common chemical reactions and relate these to actions or products in everyday life.
In this module, students plan and conduct investigations to observe chemical reactions and their effects. They pose questions, participate in investigations and solve problems to draw conclusions.
Chemical Reactions in Everyday Contexts
- Inquiry question: What is a chemical reaction?
- recognise that chemical reactions change matter into new products
- identify cooking and cleaning as common examples of chemical reactions
- investigate a range of common chemical reactions, for example:
- acid–base reactions
- soaps and detergents
- use equipment safely when investigating chemical reactions
- participate in a practical investigation to answer a question in relation to a common chemical reaction, for example:
- Which dishwashing detergent cleans the best?
- What chemical reactions occur when baking a cake?
- identify risks in participating in an investigation involving chemical reactions and describe ways to minimise these risks
- identify processes that can be involved in chemical reactions, for example heating
Acids and Bases
- Inquiry question: How are acid-base reactions present in everyday contexts?
- recognise that liquids have acidic or basic traits
- recognise that water can be both an acid and a base
- identify that the term pH represents the acidity of a substance
- conduct investigations to measure the pH level of a range of skin care and hair products
- identify the pH levels of substances that are appropriate for contact with the skin
- explore a range of acid-base neutralisations in everyday contexts, for example:
- baking soda for relief of indigestion
- neutralisation of food in the stomach
- identify that pollutants can cause acid rain
- explore the effects of and problems arising from ocean acidification
