So I have this experiment where you get any kind of food from the kitchen like coffee crystals, mustard, jam, vinegar, and so on, and then you have people smell it and guess which it is. It's for a science project that's due soon. But it has to have a question, research about the question, and a hypothesis. I can get the research, but I need help with the question and hypothesis. Can you guys help. Thanks :)
