Module 1 depth study observations pH
Students are required to make qualitative and quantitative observations and specifically analyse the quantitative data of the pH of acids and bases.
The investigating science course is multidisciplinary and develops students' abilities to engage with scientific processes to investigate personal, community and global scientific issues.
- is designed for all students and may be differentiated to suit school contexts
- promotes active inquiry and the planning and conducting of evidence-based investigations
- provides opportunities for problem-solving and making informed scientific decisions
- lets students engage in examples and situations that relate to biology, chemistry, earth sciences and physics
- is designed to complement the study of other science disciplines
- provides additional opportunities for students to develop capability and capacity in critical thinking, problem-solving and developing and communicating evidence-based arguments and making informed decisions.
In this module, students are required to make qualitative and quantitative observations and specifically analyse the quantitative data of the pH of acids and bases.
It is also suggested that students carry out a practical activity to quantitatively and qualitatively describe the characteristics of acids and bases. For these reasons, the context for this depth study is acids and bases.
During this sequence of learning, students can draw on their prior knowledge of everyday substances familiar to them. Students could investigate the acidity of soft drinks and factors affecting acidity.
They might compare the acidity of different fruit juices or could relate the acidity of household products to their uses. Students could also investigate the acidity of hair products and their effects.
Key inquiry questions
- How does observation instigate scientific investigation?
- What are the benefits and drawbacks of quantitative and qualitative observations?
- How does primary data provide evidence for further investigation?
- How does the collection and presentation of primary data affect the outcome of scientific investigation?
