Pairs Graphing: Light Levels Over Time
Pairs use a light sensor or phone app to log data every 30 minutes from dawn to dusk. They input values into spreadsheet software and create line graphs. Partners discuss patterns like peak midday light and justify graph choice.
Justify which type of graph is best for showing how light levels change during the day.
Facilitation TipDuring Pairs Graphing, circulate with a timer to keep both partners engaged in both data plotting and justification of choices.
What to look forProvide students with a small data set (e.g., daily temperatures for a week). Ask them to choose the best graph type to represent it, draw the graph, and write one sentence explaining why they chose that type.
