Chemistry: 

• Chemicals react with each other in predictable ways.
• Chemical reactions may have a negative impact on the environment, but they can also be used to address environmental challenges

By the end of this unit, students will: 

• C1. analyse a variety of safety and environmental issues associated with chemical reactions, including the ways in which chemical reactions can be applied to address environmental challenges;
• C2. investigate, through inquiry, the characteristics of chemical reactions;
• C3. demonstrate an understanding of the general principles of chemical reactions, and various ways to represent them.
