I also thought the marble activity was great!

I do a reaction similar to the iodine clock reaction, but I use sodium
thiosulfate and hydrochloric acid. The students do a serial dilution with
the thiosulfate solution and time how long it takes to become so opaque
that they can no longer see a standard mark through the solution.
