Device set up Under the source menu select the RTL-SDR/USB Click the gear icon and set the sampling rate to .900001and select the Tuner AGC setting Now click the play button and tune in to a local FM station. Appendix B: SDR Project Scoring Rubric: To be handed in with final project. 4 includes all criteria from P plus: 3 includes all criteria from BP plus: 2 includes all criteria from LP plus: 1 Communicate Fundamental principles are used to evaluate the results of an original investigation. Fundamental principles are applied to a line of inquiry where original data is collected and cited in the report. External resources are used to support discussion. Fundamental principles are demonstrated by descriptions of observations made with the SDR device. Rough draft is completed and revised for final product. Fundamental principles are stated but are not related to observations. Principles of EM waves Principles are used to inform the design of an experiment to test predicted values of properties of radio waves. Principles of waves are tested with original observations of radio waves from local resources. Observations are analyzed and compared with theoretical values. Shows the uses of radio waves through observations of a variety of sources. Describe the basic properties of waves that can be used to communicate information. Energy of the system Experimental results are formulated to make predictions about energy requirements or losses in the system with emphasis on communication closure. Energy conversion is examined including inputs and outputs of energy from the system of radio communications with specific examples from the SDR observations. Energy conversion is illustrated using observations of radio waves. Basic description of conversion of sound energy to electromagnetic radiant energy and vice versa.
4. Results – The results section contains two subsections: Data and Analysis Data - State the observations and data obtained in the lab. In this section you can use data tables, graphs and lists to convey your data. This section can include both qualitative and quantitative data. Tables and charts should be accurate, organized and include clearly labeled column names and SI units of measurement. Each graph or data table must have a descriptive title and number (i.e. Table 1: Data collected in a closed system, Graph 2: Change in mass of a chemical reaction over time). Exceeding (E) Meeting (M) In-progress (IP) Limited Progress (LP) Results: Data Includes all criteria in Meeting plus… Estimates of accuracy and error are reported. Includes all criteria in IP plus… Tables, charts, and graphs include appropriate labels and titles. Presentation done neatly with no errors. Includes all criteria in LP plus… Tables, charts, and graphs are used to illustrate basic trends in the data. Primary results are reported. Practice sketches of Graphs, Tables, Diagrams, Charts, etc…below
5. Discussion & Conclusions - In paragraph form restate the purpose/objective/research question of the lab and any hypotheses that you were testing. Provide clear statements about how your data supports or does not support your objective/hypothesis. The more specifics the better. You should be referencing back to your class lessons to help you make connections between the data and WHAT the data means. If instructed directly by your teacher put your work into broader context, how do your research results relate to the larger world (use references)? Next you should state what problems may have occurred and what changes might be helpful in clarifying your results. Was there any introduction of error? If so what caused the error. Human error is not an appropriate description of the error you need to be specific. To be “Exceeding” in any class: You need to complete all other parts of the discussion and include any changes to your experiment that might be helpful in clarifying your results. Come up with a new but related testable research question that would help further your understanding of the topic. Exceeding (E) Meeting (M) In-progress (IP) Limited Progress (LP) Discussion Includes all criteria in Meeting plus… Suggests a related testable research question is provided. Strengths and limitations (errors) and makes valid suggestions on how to reduce the error. Includes all criteria in IP plus… Connection back to hypotheses is correct based on the results. Relationship between variables is discussed, patterns are logically explained. Results are connected back to and integrated with the learning objectives or topics of study from class. Includes all criteria in LP plus… Original research question and hypotheses are presented. Results are discussed in terms of supporting or not supporting the hypotheses. Results are discussed in relation to the original purpose or question.
