For my At-home Experiment I chose to use vinegar. I chose vinegar because it is very useful in regular life, and I was interested in what its value is for chemistry.
You did well on the physical properties but I think you could have found out some of the Chemical properties by the experiments you did yourself, so I don't think you had to site all of those websites. And I don't understand how the penny was cleaned? Did you mix salt in the solution and then put the penny in it, or did the penny have salt on it already? Other than that great job.
You have great pictures and had creative properties. It could be more helpful if you added more explanation to why they were either physical or chemical properties. But over all great job!
