Professional Commentary

The purpose of this lesson is to determine the pattern (length and direction) of shadows cast by sunlight over several months to develop an interpretation of the daily and seasonal patterns and variations observed. Students make observations, collect data and create a table of the times, lengths of lines, and angles for the shadow data. Throughout the course of the year students collect, analyze, and compare this data to past months. (author/cb/fh)

Benchmarks (6–8)
Describe how the positions and motions of the objects in the universe cause predictable and cyclic events.
Grade Level Indicators (Grade 8)
Describe how objects in the Solar System are in regular and predictable motions that explain such phenomena as days, years, seasons, eclipses, tides and moon cycles.
Scientific Inquiry
Benchmarks (6–8)
Analyze and interpret data from scientific investigations using appropriate mathematical skills in order to draw valid conclusions.
Grade Level Indicators (Grade 7)
Use graphs, tables and charts to study physical phenomena and infer mathematical relationships between variables (e.g., speed, density).
Grade Level Indicators (Grade 8)
Read, construct and interpret data in various forms produced by self and others in both written and oral form (e.g., tables, charts, maps, graphs, diagrams, symbols).
