Today in class we: -maked the lab from tusday (water testing)
-we started a new lab
-reviewed for our unit test by playing Jeopardy.
The water testing lab that we did yesterday was not very accurate, mainly becuase we started to run out of time. We tested the creek water first, so we almost ran out of time before had tested the golf corse pond water.
The purpose of the expeiment today was to find the calorie loss or calorimetry in different types of foods. In doing this, we had to measure the water temperature before and after we burned the food stuff. We also had to measure food in order to calculate the results properly, because some of foods were bigger, and the results would not have been accurate.
In my hypothesis I guessed that the peanut would burn longer and give off more heat, but suprisingly the cheezie did. After the lab, we played Jeopardy to review for our unit test.
Personally I found this lab interesting because the results turned out opposite of what I had expected. But on the other hand the results weren't completly accurate, because to food did not burn completly.
When i went to google, i searched for 'food calorimetry', and about 3 of the sites that came up was the experiment that we did...lol.

Hi Tane,
I'm sticking with your 3/3 mark, but recognize that requirement 2 and 3 need work for next time. Going to a site showing the same experiment doesn't really meet "above and beyond". Also, try to extend your thoughts. WHY was the experiment not accurate? HOW could you make it more accurate? DO they really burn living things for pyramid of energy studies? etc
You'll need more next time to get 3/3
