Minimum Soil Temperatures for Sprouting 32° F 70° F Spinach Lima Beans
Focus Question: Which location would allow seeds to sprout earliest in the spring?
Investigation Question: • Which location the north side or the south side of the building has the highest soil temperature 5 cm below the surface?
Investigation • Practice measuring soil temperature • Prediction • Description of study site • Compare 2 locations (changed variable) • Measure and record soil temperature (measured variable) • Measure soil temperature 5 cm into ground, wait 1 minute, read thermometer while in ground (kept the same variables) • Multiple trials
Analyze DataFinding Median or Mode • Individually • Class North Location Soil Temperatures ° F 48 46 48 46 48 42 46 48 50 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 50 52 54 56 58 50 52 54 54 54 South Location Soil Temperatures ° F
Writing Conclusions • Answer the investigative question (use words from the question). • Support your answer with qualitative data (less, more) and quantitative data (median/mode temperatures). • Tell whether or not the data support your prediction. If not, how has your thinking changed?
