One of the more popular chemistry assignments is a scavenger hunt, where students are asked to identify or bring in items that fit a description. Examples of scavenger hunt items are things like 'an element' or 'a heterogeneous mixture'. Are there additional items you would add to a scavenger hunt or that you have been asked to find for an assignment?

What a nice idea
Bravo, this excellent thought has to be precisely on purpose
Exceptional delirium
I think, that you commit an error. I can prove it. Write to me in PM.
This excellent idea is necessary just by the way
I agree, useful information
I am sorry, that has interfered... This situation is familiar To me. It is possible to discuss. Write here or in PM.
It is remarkable, very amusing phrase
