Does size matter? Making choices always involves compromise What factors need to be considered when making a decision? What’s good for you may not be good for others. How do outside factors impact decision making? How do we analyze relationships in a system? Marking Period 6 Week 30-36 Sustainable Systems How do outside factors impact business operations? Scaffolding Questions How do you make a good business decision? What effect do fixed and variable costs have on profitability? Which linear representation is most useful? How do income and expense affect profitability? How do you determine profitability? What do you need to consider in managing your resources? How is profit represented graphically? How does area serve as a resource for all living things? Under what circumstances do you need to consider adjusting how you operate? How are graphs, equations, and tables related and what information can be gathered from each? What real world examples can be represented by quadratic functions? What are the similarities and differences between linear and quadratic functions? How do you use a graph to justify the choices you make? How does the pattern of cell growth impact the advances in medicine? Do all cells grow at the same rate? How does triangulation of points help to determine distances? What is the relationship between side lengths and areas? How do our actions impact the space available for living things? How can you use knowledge about 3 dimensional shapes to create a sustainable “green” building? What is the relationship between surface area and volume?
