In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings. Once they begin to sprout, make predictions: How tall will the plants be in a week? in a month? Each week, learners measure and record the height of their plants. They explore change over time as they compare predictions and results, and as they analyze whether their plants grew about the same amount each week. Available as a web page and downloadable pdf.
