What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

If you have ever had to adjust to a new time zone, you have noticed that it takes a while before you start to feel normal again. By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms....

Students make two models to stimulate the cooling rate of different skin surface areas. They use a Temperature Sensor to measure the cooling rate of the models. The students also compare the cooling rates of the models to determine the...

Using physiology monitoring, students will understand how to collect data using scientific methods in this activity. Students will also learn how to communicate the finding in a lab report. Physiology monitoring will include measuring...
