In Year 7 Science, students describe techniques to separate pure substances from mixtures. They represent and predict the effects of unbalanced forces, including Earth’s gravity, on motion. They explain how the relative positions of Earth, the sun and moon affect phenomena on Earth. They analyse how the sustainable use of resources depends on the way they are formed and cycle through Earth systems. They predict the effect of human and environmental changes on interactions between organisms and classify and organise diverse organisms based on observable differences. Students describe situations where scientific knowledge from different science disciplines and diverse cultures has been used to solve a real-world problem. They explain implications of the solution for different groups in society.
Students identify questions that can be investigated scientifically. They plan fair experimental methods, identifying variables to be changed and measured. They select equipment that improves fairness and accuracy and describe how they considered safety. Students draw on evidence to support their conclusions. They summarise data from different sources, describe trends and refer to the quality of their data when suggesting improvements to their methods. They communicate their ideas, methods and findings using scientific language and appropriate representations.

The following topics provide the framework for learning in Year 7 Science:
ASSESSMENT
Students are assessed through a range of tests, assignments and practical reports. Students use the scientific method to conduct investigations, collect, analyse and communicate results.
In semester 1 students study chemical and biological sciences. In chemical sciences, students will use a range of separation techniques to separate a dry heterogenous mixture and explore the environment and economic effects of wet wipes on the environment. In biological sciences, students investigate how different factors, such as temperature and environment, affects rates of decomposition. Students will also be tested on their knowledge and understanding of classifications of animals and plants.
In semester 2 students study physical and earth and space sciences. In physical sciences, students explore a range of balanced and unbalanced forces, investigate the relationship between changing friction and work and investigate how simple machines can also be used to reduce work done. In earth and space sciences, students investigate the impacts of space science careers or how scientists have helped changed our understanding of space sciences. Students will be tested on their knowledge and understanding of forces in space.
Students are assessed against the IB MYP Science assessment criteria:
Criteria A: Knowledge and Understanding
Criteria B: Inquiring and Designing
Criteria C: Processing and Evaluating
Criteria D: Reflection on the Impact of Science
CARE • COMMITMENT • CO-OPERATION • RESPECT
