Beat the heat using sensors. Scholars research normal body temperatures for humans and a specific animal. In groups, they create sensors that monitor body temperature, as well as the weather. The goal is to reduce the occurrence of heat...

Using the TI-Nspire calculator, statisicians identify outliers and their effect on the least-squares regression line. In finding the line of best fit, they determine what points will affect the least squares regressions and what points...

Not all species can survive in all habitats. Using specific criteria, learners assess the fitness of a local habitat to a specific species. They collect data and suggest enhancements to create a suitable habitat for their chosen species.

"Equal pay for equal work!" may sound logical but it is not the reality. High schoolers begin a study of the gender wage gap with an activity that asks them to position themselves along a line that indicates whether they strongly agree...

Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...

Students collect and analyze data from the United States Census Bureau. Using spreadsheet technology, students explore their results and make preductions about income groups. Students compute the mean, median and mode. They create...
