Studying the physical properties of matter is a perfect opportunity for students to learn to collet data using probes. This process requires some pre-planning but gives students large and interesting data sets. The pictures below illustrate students transferring data from one calculator to the next using a cable.
This lab is interesting because the graph of the temperature versus time for boiling water and salt water is roughly logistic, because there is a maximum temperature, which causes state change in water from liquid to gas. Students often think that anything can be continued to be heated and increase in temperature and the dramatic graphs make this much clearer for them.
Once the students have transferrer their data to their calculators, they can copy the data to their computers using a free download, TI Connect, from Texas Instruments.
Early exposure to this technology prepares students for the rigors of high school.
