Information in Radio Waves Radio Observations of Space Weather: Summative Assessment Competencies being Assessed: Develop a model based on evidence to illustrate the life span of the sun and the role of nuclear HS-­‐ESS1-­‐1 fusion in the sun’s core to release energy in the form of radiation. Use a model to describe how variations in the flow of energy into and out of Earth’s systems HS-­‐ESS2-­‐4 result in changes in climate. Scoring Rubric: 4 All criteria from 1-­‐3 plus: 3 All criteria from 1-­‐2 plus: 2 1 All criteria from 1 plus: Part 1 completed accurately Part1: Foundations Diagram and label the correct parts of the Atmosphere including elevations above sea level. RET 2013 Atmospheric Structure Stratosphere Ionosphere Troposphere Exosphere Thermosphere 1 Information in Radio Waves Label the correct parts of the solar interior and atmosphere photosphere Sun’s structure Convective zone Flare Chromosphere Coronal Hole Core Radiative zone Sunspots Prominence Part 2: Applications 1. Describe the effect of the night and day differences in AM radio transmission and what does this tell us about the ionosphere? 2. What is the primary evidence for fusion in the core of the sun being the primary source of energy for the sun and consequently us. RET 2013 2 Information in Radio Waves 3. What are some surface features of the sun that are associated with : a. Convection beneath the photosphere b. Lower surface temperature c. Broad regional loops in magnetic field lines d. The projection of material out of the solar atmosphere into the interplanetary solar wind. e. When magnetic field lines break and reform again Part 3: Extensions Using a model of the energy budget for solar radiation and using your model and the temperature profile of the atmosphere. Make an argument for the cause and effect relationship between atmospheric composition and the temperature profile of the atmosphere. RET 2013 3 Information in Radio Waves Shapley, 2012 RET 2013 4
