Chemistry : Earth, its resources and atmosphere
Overview
Students will learn about the composition of the Earth by being able to describe its layered structure. They will see how the formation of the three types of rocks found on Earth; igneous, sedimentary and metamorphic are all part of larger continuous cycle called the rock cycle.They will focus on the Earth as a source of limited resources and the importance of recycling. Lastly, students will look at the carbon cycle and the delicate composition of Earth’s atmosphere. Students will realise that the production of carbon dioxide by human activity has a large impact on our climate.
