The content we are focusing on in our science experiment is how heat can be created by rubbing two objects together, such as hands or cloth. We are also exploring whether lubricating the two objects (lotioning the hands or wetting the cloth) will affect the temperature change. In order to explore this scientific content area, we are using the pedagogical tool of exploring and experimenting to find out what happens--instead of just being told that two objects rubbed together creates heat, students have the opportunity to actually experience it which will help them to remember it easier. Scientific content is always better when it is a hands-on experience, because that is how the scientists discovered it, and so it helps the students to discover it the same way. We used probes in our experiment because we are dealing with temperature change, and this helps to tell the temperature and the temperature change. The graph the technology creates is also helpful in seeing the temperature change and how the heat is created by rubbing the objects together.
