Movement of a Thermometer

The video tutorial explains how thermometers work, focusing on mercury thermometers. It describes the scientific method and guides viewers through an experiment to observe how mercury reacts to different water temperatures. The experiment involves using a thermometer to measure temperatures in various water conditions, demonstrating the principles of heat energy and expansion. Observations show the correlation between water temperature and mercury movement, reinforcing the concept of temperature measurement.

Explain the scientific method and its importance in conducting experiments.

What observations should you make when placing the thermometer in cold water after heating it?
