Energy from Peanut and Pea
Hypothesis
I think that the peanut will release more energy, as it 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.
Variables
Independent variable: Pea, Peanut Dependent variable: Temperature Controlled variable: Beaker volume, Bunsen burner Equipment Beaker, water, Bunsen burner, pea, peanut, thermometer, toothpick (holding food), heat tile, grabber.
Procedure
- First, get equipment
- Setup equipment
- Put water in a beaker, then grab with a grabber
- Burn peanut/ pea with a toothpick
- Put the food under the beaker
- Record Temperature
Result
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 |
Discussion
This experiment wasn’t really successful, as there weren’t 4 trials for the pea. Also, some Peanuts/Pea were much bigger than others, next time I will try to choose the sizes more carefully next time.
The peanut had a large range of temperatures, 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 runs out of energy in the middle of a test. Which caused the problem of recording its temperature. Next time maybe there should be a better light so that there wouldn’t be a problem with burning the food. There could be fewer people disturbing the experiment so that more results could be recorded. For example, when people talk, the sound wave blows out the fire. All of these results that the information wasn’t really accurate. Conclusion
As you could see the peanuts average Temperature was higher than the pea, as the pea has less oil then the peanut. The amount of oil on the Peanut is far greater, as resulting in more energy released from the peanut. While on the other hand, the Pea has less oil which was shown as there was less energy. This shows that the Peanut has at least 3 times more energy than the Pea. Further study Does more oil cause more energy released? “YES” it does. More oil will help to release more energy, this is shown as today, many cars rely on oil to run.
