So for a practical sac for chem, we had to create a experiment and conduct it. I chose to test whether the Mighty grain cereal (Coles trying to copy Nutrigrain) has more energy per 100g as it claims than the actual Nutrigrain branded cereal. I conducted many trials of burning each type of cereal several times and using the heat to increase the temperature of the water and then calculate the practical yield of energy released for each type.The results pointed out that the actual branded cereal had more energy even though slight but still noticeable compared to the generic brand. Now that i am up to the stage of writing the report, I have no idea what my hypothesis should be because i cant really use any scientific theory to support what i thought. I don't know how to incorporate any scientific theory taught in year 12 for this simple experiment because its a comparison one, at most i can say this will have more than the other. No knowledge acquired this year can be used to say why one will have more than the other, except for the information given on each cereal box. please help me

with coming up with an hypothesis which is supported by scientific theory.
