Insulation Challenge-By Ajay Trinh

Oct 6, 2016 11:02:58 AM.jpgLately in Science/Tech, we’ve been working on insulation. Insulation is an object that traps heat. In class, we work in groups and experiment what objects are good insulators. The objects that we (and most people) chose to use were, tin foil, styrofoam, plastic, and cardboard. We used a wireless temperature sensor as a thermometer which would give us information on to a computer. Our group wrapped our items around the plastic cups we used to see which would be the best insulator. For our group, the best insulator was the styrofoam. It was styrofoam because when we put it into the water then put the thermometer sensor in, the temperature went up.

One of our big problems was that when we tried making a hole for the thermometer sensor through the tin foil ripped some which was a minor problem. Another problem was that sometimes the water was too hot and melted the cup! The majority of the time, the temperature stayed at one spot, then either moved down a little, or moved up a lot (probably because the sensor was warming up and we needed to give it time). This experiment was awesome! I hope we get to do it again but with more insulators!

    I also learned that plastic wrap was not a very good insulator. Also I think it is cool that your group got up to 140 degrees.

  2. This was a really good writing style! There were lots of specifics too.

  3. I think the plastic wrap did it.We got to 186 F.This was very fun.I hope that we can to another insulation challenge

  4. I enjoyed the insulation challenge to but i think my group didnt work as good as you did

  5. Good job on describing the insulators and problems and the details of the project.
