As your students and our students make their way through this new age of technology, who is there to teach them about technology? That is precisely why we, as teachers, are striving to achieve the title of “Tech Savvy Teacher”. We believe as Tech Savvy Teachers we will be able to prepare our students to enter into a world that relies heavily on technology. So, you ask, what is a “Tech Savvy Teacher”? A Tech Savvy Teacher knows how to use all kinds of technology tools to enhance the classroom. They also know how to use the tools to engage the children in their own learning. Not only does a Tech Savvy Teacher know how to use these technologies, but they also know how to access the newest technologies that are emerging every day.

For our science activity we decided to explore temperature and friction. This falls in the 3rd grade standard 5, objective 3, which is: Demonstrate that heat may be produced when objects are rubbed against one another. We used temperature probes, computer software, our hands, lotion, and carpet. First, we connected the temperature probes to the computer and let the software read the initial temperature, which was 23.7 degrees Celsius. Next, we rubbed our hands over the probe and took a picture of the reading, it rose to 29 degrees. In between each reading we let the probe cool down to the original temperature. Then, we saw the effects that lotion would have on the same procedure, by putting lotion on our hands and rubbing the probe between our hands, the reading this time was 31.2 degrees. Lastly, we rubbed the temperature probe on carpet. This showed the greatest increase in temperature, which was 34.1 degrees. This showed the heat than can be produced by varying amounts of friction.

Students would be able to explore friction and temperature to a greater degree with the technology of temperature probes. They would also be able to watch the graphs that were produced using the computer software. This data that they see on the graph can be collected and analyzed, leading to their own conclusion. Instead of just saying friction causes heat, they can see the actual numbers and the line on the graph that the measure of heat produces. This also provides a hands-on experience instead of having a teacher lecture the same material.
