What is in our food?
When we burned the food we had a reason. Why would we just burn food? The reason we burned the food was because we wanted to find out how much energy is in our food. To do this we needed to have some special equipment for the experiment. Here is a list of things we needed:
All of these do different things that are important to the experiment. The mounted needle Is important so we don't burn ourselves when we have the burning crisps and the Bunsen burner is important because it allows us to actually burn the crisps (very Important when we are doing an experiment about burning stuff).
How did we do it?
Now you may be wondering how we did the experiment. It is actually very simple. All we did was:
- We put the water in the boiling tube
- We put the boiling tube in the clamp
- We turn on the Bunsen Burner
- We look at the temperature of the water
- We light the crisp on fire
- We put the flaming crisp under the boiling tube
- When the crisp is burned out we pull it away
- We then look at the tempurature of the water and write it down
How did we work out the energy?
This was very simple. All we had to do was:
Mass of water + tempurature increase x 4.2 / Mass of food sample
The answer to that is the amount of energy in the food sample.
Results!
Now you may be wondering what happened when we finished. We wrote our results on paper and put all our equipment away. Here are the results:
Wotsit - 1344J released
Quaver - 1773.33J released
Hula Hoop - 2061.81J released
Walkers 1470J
As you can see, the Hula Hoop release the most energy. So if you want energy, eat Hula Hoops.
