Secondary learners investigate exponential functions in a real-world scenario. They collect data on the temperature of a cooling baked potato, enter the data into lists, and graph the data using a scatter plot before finding an...

Does a linear or exponential model fit the data better? Guide your class through an exploration to answer this question. Pupils create an exponential and linear model for a data set and draw conclusions, based on predictions and the...

In this activity, students collect the height versus time data of a bouncing ball using the CBR 2. They find the relationship between the bounce number and the bounce height. They learn to graph scatter plots, calculate the maximum value...
