At Durham Academy in 6th grade science we had a project to make a heat shield.
The heat shield had to withstand 2000 degrees Celsius for three minutes. At the other side of the heat shield there was an egg and if you cook the egg the heat shield did not work. Everyone got 100 credits.before anyone made there final design we could do test with a heat gun that got up to 400 degrees Celsius. The tests were only one minute long. My group used up 95 credits and this was our prototype.
We chose this prototype because we thought the aluminum would radiate the heat away. The aluminum was not good in the real test because the heat was to hot it burned through the aluminum foil. We chose the sponge because in the testing it was great. The sponge in the real test was not good it burned right after the aluminum. We chose the metal lathe because we thought it would absorb the heat. The metal lathe was great in the real test it did not let much heat go through.
Here is the picture of before and after the final test.
The blow torch made a hole in the heat shield but our egg was still RAW.
My parter’s were Michaela and Layla.
