Determine the central ideas or conclusions of a text; provide an accurate summary of the text distinct from prior knowledge or opinions.RST.68.8. Distinguish among facts, reasoned judgment based on research findings, and speculation in a text. RST.68.9. Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text on the same topic. Common Core Math Standard: CCS.8.SP.A.1 Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities; CCS.8.SP.A.2 Know that straight lines are widely used to model relationships between two quantitative variables; CCS.8.SP.A.3 Use the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept.


Video Engagement: What are Radioisotope Power Systems? NASA uses Radioisotope Power Systems, or RPS, to convert heat from radioactive decay to electricity, creating predictable, continuous power for long missions in extreme environments. Learn how a next generation Radioisotope Stirling Engine will perform four times more efficiently and help NASA use even less of a precious resource. (7 minutes) View Program

Problem I  Solar Electricity  Students calculate the sizes of solar power arrays and their generated power and learn about the watts per square meter efficiency factor. [ Open PDF ] Problem II  Radioisotope Thermoelectric Systems  Students perform basic math related to RTGs including temperature conversion and mass verses power calculations. [ Open PDF ] Explain your thinking: Write your own problem  Using information found in the Math Connection problems, the press release or the video program, create your own math problem. Explain why you set the problem up this way, and how you might find its answer. Evaluate your understanding: Challenge Problem  Designing a Power System for Juno. Solar and RTG systems produce electricity, but each requires a specific amount of mass to do so. In this problem, students compare the mass versus output electricity for both systems to estimate their masses for the Juno mission. [ Open PDF ]
