Science Buddies: "Ask an Expert"

I am doing The Cool Blue Light of Luminol science fair project and i am trying to make it my own with testing it in different temperatures but I don't know how to got about doing that . Please help me with this, you don't have to tell me what to do but just give me ideas on ways of going about that. Thank you so much for helping me!!!!

My hypothesis is this: If the Luminol is in room temperature (control group) then it will glow brighter because the electrons will be able to move better than in cool or cold temperatures. Is it okay that it is my control group or should i make something else my hypothesis or change my control group.

Hi Jenlopy,

Having your control group be at room temperature is a fine option, if your independent variable is temperature. Just make sure that everything except temperature (e.g., amount of luminol added, volume of water, etc.) is the same among all your samples. Your hypothesis is a good one - especially because you not only said what you think will happen, but also why you think that.

Another student had questions on this Project Idea that are similar to yours; I answered his questions here:
