Caring for our carbon
We all live, eat, breathe and use carbon every day … without even thinking about it! Carbon is all around us and available to us in many different forms – as an atmospheric gas, as an energy source, and as a food source. When we eat a sandwich, turn on the engine in the car, or switch on the television, we are literally consuming carbon. But where did this carbon originally come from? Besides being able to watch our favourite program and eat our favourite food, what else happens when we use this carbon? The Caring for our carbon unit is an ideal way to investigate the science of carbon and improve the scientific literacy of students in the classroom. It provides opportunities for students to investigate their understandings of carbon – where it comes from and how we use it, and what happens when we use too much of it – and through discussion and debate, arrive at their own considered opinion about how we should be using carbon to live sustainably in the future.
