6B

Inquiry - How do our choices with chemical use impact the world around us?

This term in Level 6, we are learning about chemical science and how chemical use plays a role in sustainable development.

Students began the unit by exploring a range of concepts, such as the properties of matter (solids, liquids and gases) and the reversibility/irreversibility of physical changes and chemical reactions. These concepts were put into context through a range of scientific experiments and hands-on investigations that they engaged in. For example, students investigated variables that impact the melting of ice, a physical change of state, by testing variables such as placement in locations with different levels of sunlight and the introduction of other materials like salt. Furthermore, they participated in an experiment focusing on the chemical reaction that occurs when vinegar is mixed with bicarbonate soda. Students developed their understanding of independent, dependent and controlled variables, experimenting with different factors to understand its effect on the duration of the reaction.

Through these experiences, students strengthened their science inquiry skills; their capacity to question, predict, analyse and communicate their findings. Looking forward to the later stages of the term and Inquiry unit, we will be focusing on how individual consumers, the wider community and large-scale organisations utilise chemicals, and the ethical nature of their usage.
