YEAR 8 SCIENCE – COURSE 1 IMCC2015: TERM 4 EARTH SCIENCE & INQUIRY SKILLS Year 8 Level Description The Science Inquiry Skills and Science as a Human Endeavour strands are described across a two-year band. In their planning, schools and teachers refer to the expectations outlined in the Achievement Standard and also to the content of the Science Understanding strand for the relevant year level to ensure that these two strands are addressed over the two-year period. The three strands of the curriculum are interrelated and their content is taught in an integrated way. The Science as a Human Endeavour strand can provide relevant contexts in which science can be taught. The order and detail in which the content descriptions are organised into teaching/learning programs are decisions to be made by the teacher. Over Years 7 to 10, students develop their understanding of microscopic and atomic structures; how systems at a range of scales are shaped by flows of energy and matter and interactions due to forces, and develop the ability to quantify changes and relative amounts. In Year 8, students are introduced to cells as microscopic structures that explain macroscopic properties of living systems. They link form and function at a cellular level and explore the organisation of body systems in terms of flows of matter between interdependent organs. Similarly, they explore changes in matter at a particle level, and distinguish between chemical and physical change. They begin to classify different forms of energy, and describe the role of energy in causing change in systems, including the role of heat and kinetic energy in the rock cycle. Students use experimentation to isolate relationships between components in systems and explain these relationships through increasingly complex representations. They make predictions and propose explanations, drawing on evidence to support their views. Use and influence of science Planning and conducting Science and technology contribute to finding solutions to a range of contemporary issues; these solutions may impact on other areas of society and involve ethical considerations (ACSHE135) Collaboratively and individually plan and conduct a range of investigation types, including fieldwork and experiments, ensuring safety and ethical guidelines are followed (ACSIS140) Science understanding influences the development of practices in areas of human activity such as industry, agriculture and marine and terrestrial resource management (ACSHE136) In fair tests, measure and control variables, and select equipment to collect data with accuracy appropriate to the task (ACSIS141) Year 8 Content Descriptions Science Understandings Earth and space sciences 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 Processing and analysing data and information Nature and development of science Scientific knowledge changes as new evidence becomes available, and some scientific discoveries have significantly changed people’s understanding of the world (ACSHE134) Science knowledge can develop through collaboration and connecting ideas across the disciplines of science (ACSHE226) People use understanding and skills from across the disciplines of science in their occupations (ACSHE227) Science Inquiry Skills Construct and use a range of representations, including graphs, keys and models to represent and analyse patterns or relationships, including using digital technologies as appropriate (ACSIS144) Questioning and predicting Identify questions and problems that can be investigated scientifically and make predictions based on scientific knowledge (ACSIS139) Summarise data, from students’ own investigations and secondary sources, and use scientific understanding to identify relationships and draw conclusions (ACSIS145) Use scientific knowledge and findings from investigations to evaluate claims (ACSIS234) Evaluating Reflect on the method used to investigate a question or solve a problem, including evaluating the quality of the data collected, and identify improvements to the method (ACSIS146) Communicate ideas, findings and solutions to problems using scientific language and representations using digital technologies as appropriate (ACSIS148) Communicating Year 8 Earth & Space Sciences Program Term 4 2015.

Density of an irregular shape (6.3; 2) Pearson chapter 6.3 Density investigation Define density as how much mass is in a unit of a substance. (How much can be packed into a small section of an object). Model to students how to calculate the density of an object. Start with a regular shape (square/rectangle) then move to irregular shape. Extend students by allowing them to use the decanting tins/cylinders to calculate density. 8 Revision & Test Unit test Assessment Outline ASSESSMENT TYPE TITLE WEIGHTING Practical Assessment Thermal capacity 6% Practical Assessment Density 6% Unit test Unit Test 8%
