I'm doing the fresh fruit vs canned fruit experiment and if I prepared the fruit a different way would it effect the gelatin
WARRIOR [948]

Answer:

How the gelatin is prepared can affect the result.

Explanation:

To perform this experiment efficiently, you need to prepare the jelly made from fresh fruit and the jelly made from canned fruit equally. That's because if you modify the ways of preparing the gelatins, they will show many differences and you won't be able to tell if this difference was caused only by the nature of the fruits, or by the way of preparation. Therefore, the way the gelatins were prepared can modify the experiment result and leave it imprecise and unreliable.
