Thank you for the opportunity to help you with your question!
Well, the answer to this question depends if the Chemistry project is for high school or college. If for high school, you could do a project on how to make ice cream using liquid nitrogen. Or, a cool project could be making many different reactions to test the solubility rules. This project would include making solutions that would cause "precipitation". Thus, this would mean mixing up chemicals/reactants to make both solutions that would be soluble and ones that would be insoluble. The insoluble solutions would cause precipitation.
Now, if the project is for college, I would suggest making a project over Blue Bottle Chemistry. This involves making up a solution that will turn from blue to clear and back to blue with just a few shakes. It's pretty cool actually. There are ways to do it with the colors of a stop light as well (yellow, red, and green). To do any of these three projects, it's very easy to just google any of them and it will give you step by step procedures of completing them. I have done all these demonstrations before for Chemistry classes I am a teaching assistant for. I know what students like to see. The Blue Bottle and Stop Light demonstrations were by far the coolest for our students. If you do not find answers/procedures on Google, let me know and I will help you out!Please let me know if you need any clarification. I'm always happy to answer your questions.
I think I might do the blue bottle! That seems very interesting. I checked it out on Google. What would the hypothesis, control group, and indep/dep variable? I've always had trouble with those. I'm a sophomore in high school, but it is a college leveled class.
Nevermind, I think I got it! Thank you for the idea :)
Well, there are a few ways to set up an experiment like this with different hypotheses. However, I believe the easiest way to go is using concentration as an independent variable and the rate of the reaction as a dependent variable. Since this would be a kinetics experiment dealing with reduction/oxidation reactions, the hypothesis could be that as the concentration of lets say potassium hydroxide increases, the rate of the reaction either increases/decreases. You would have to do a little research on whether the rate of reaction would increase or decrease. Or, you can simply make the hypothesis state that the rate of reaction changes as the concentration changes.
No problem! Let me know whenever you need any Chemistry help! I have a B.S. in Chemistry and about to start my PhD in Chemistry as well :)
