Energy makes things happen, but what is it made of? Scientists say that the amount of matter and energy in the universe is fixed, so how did the different rocks and minerals form on Earth, and where do we get our energy from?
Year 8 start the term by investigating different types of energy and observing the energy transformations in nature and in everyday life. They consider energy efficient housing and look at innovations that are changing the way we live. Finally, they discover that they don’t know as much about sound and light as they thought they did.
Next, they delve deep into the structure of the Earth and investigate the formation of different types of rocks and minerals in their local areas. They look at the earths mineral resources and examine different mining methods and recent Australian innovations. Without giving too much away, for those who collect rocks or crystals, the last week of term will include a very interesting excursion. And it may include Australian dinosaurs.
Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and transfers cause change within systems (ACSSU 155)
Sedimentary, igneous and metamorphic rocks contain minerals and are formed by processes that occur within Earth over a variety of timescales (ACSSU153)
Science as a human endeavour
Scientists construct explanations about the natural world based on evidence and these explanations change when new evidence becomes available. The science of today will lead to the technology of tomorrow as scientists work collaboratively, using new skills and modern methods. Only a high level of scientific understanding among people of all cultures will ensure that governments follow ethical considerations when legislating the use of emerging technology. (ACSHE 119, 223, 120, 121)
Science inquiry skills
This term Year 8 will work individually or in small groups to produce a project on energy or the Earth’s resources, which allows student choice; is organized around an open-ended question; requires inquiry to learn and/or create something new; requires critical thinking, problem-solving, collaboration, and various forms of communication (often known as 21st-century skills); incorporates feedback and revision and results in a presentation. (ACSIS 124, 125, 126, 129, 130, 131, 132, 133)
