Hot Water Heater
:Goal: To design an efficient water heater for our house.
Data:
Time Temp ('c)
0 18
5 16
10 14
15 10
20 10
Heat gain:-8
Radiation: The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization
Conduction: Energy is transferred by the movement of electrons or ions.
Convection: Heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
Insulation:The reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radioactive influence.
Our design was made to use convection to cycle water through a heating element and back into the water containers. Our design did not work and ended up decreasing in temperature by 8 °C.

Daylighting/ exparmental House
Goal: to test out several daylighting techniques in a cardboard house of our design. We used this diagram to help us with our experiments in window angle and placement.
Heat Testing Lab

2. The rapid temperature change of materials such as carpet, drywall, hardwood, redwood, and plywood shows that they have a low specific heat capacity. And the slow cooling of materials such as cement blocks, tiles, and red brick shows that those materials have a high heat capacity.
4. The reason why this lab may have not been consistent is because some students may have been checking the temperatures at inconsistent times. Students also may have been taking temperatures at different distances, and therefore making the area covered by the laser larger, as well as checking the temperature at different locations on the material. Another error that was addressed was the fact that we were using a laser thermometer on reflective materials. 5. We could improve by making the the errors more consistent. We could mark where the laser would be when taking the temperature as well as each group starting the experiment two minutes before the other group. 6. Other thing we could do to advance our findings would be to have our materials go through extreme climates, seasonal changes, and have the materials exposed outside when it is sunny. Conclusion
2. In our lab we put a heat lamp over certain materials used in building a house. When ten minutes passed, we would turn off the light and monitor the temperature change. 3. |
4.As you can see, when subjected to 240’ temperatures, fiberglass and rigid foam are the best insulators when building. And As seen in the graph below, woods are horrible insulators. When the light is off the heat subsides rapidly from the wood, as well as the carpet.
5. Because fiberglass and rigid foam can hold 105’ and 108’ temperatures after 10 minutes of 240’ temperature and 10 of cooling, those two materials are the best to use out of all the insulators. And because, heat rapidly subsides from carpet and woods, you should avoid those materials for insulation.

We plan to use solar to generate our power
Relfelction
The project went well in most regards, I know I could have been more cooperative in my part during the beginning of this project. I also know that I could have given some thought of some of the ideas that were put on the table. And and we disagreed on certain topics, which kind of hindered the project for us. But despite that we did a good job in regards to time, we did not have to race to Finnish the presentation or the project, and to link this with the last pit, Zoe and I have settled our differences and began working together with less fighting. And lastly, the combo if people in our group suited us, we had a leader we had a designer and a designer. It's best to have a leader to keep us organized and on task.
