I think that the peanut will release more Energy, as it is has more oil which will generate more energy. While the pea does not have as much oil as the peanut, so the pea will make less energy.
Independent variable: Pea, Peanut
Dependent variable: Temperature
Controlled variable: Beaker volume, Bunsen burner
Beaker, water, Bunsen burner, pea, peanut, thermometer, toothpick (holding food), heat tile, grabber
1. First get equipment
2. Setup equipment
3. Put water in beaker, then grab with a grabber
4. Burn peanut/ pea with toothpick
5. Put the food under beaker
6. Record Temperature
Table 1: Looking at the first table, the amount of water added to the beaker was 20ml. There were 4 trials for each food, except for the pea. Type of Food| Heat (°C)|
| Trial| Average|
| 1| 2| 3| 4| |
Peanut| 20| 35| 50| 59| 41|
Pea| 8.5| 5| 31| | 14.83333|
This Experiment wasn’t really successful, as there weren’t 4 trials for the pea.Also some Peanuts/Pea were much bigger than other, next time I will try to choose the sizes more carefully next time. The peanut had a large range of temperature, this tells us either the thermometer is broken or the test was not conducted well. Maybe, the Pea could be changed with another food, as it frequently run out of energy in the middle of a test. Which caused the problem of recording its temprature. Next time maybe there should be better lighter, so that there wouldn’t be a problem with burning the food. There could be less people disturbing experiment, so that more results could be recorded. For example, when people talk, the sound wave blows out the fire. All of this results that the informaion, wasn’t really accurate.
As you could see the peanuts average Temperature was higher then the pea, as the pea has...
