We began by placing our vial containing adult drosophila in the freezer for 15 minutes, until the flies stopped moving. During this time we labeled four plastic vials with our group name, lab section, and the date and treatment containing appropriate ecdysone hormone concentrations. We put 2 grams of dehydrated fly media in the bottom of each tube, then added 10 mL of water or the appropriate concentration of reagent (control (water), 0.1, 1.0, and 10 µM of ecdysone). We mixed tthese to create blue, uniform medias in each vial. Then we moved this vial to our ice bucket to sort the flies. We added adult flies to the vials by using a soft brush to gently sweep two male and two female flies into each separate vial, inserting cotton stoppers, and laying the vials on their sides until the flies regain consciousness. The vials were then placed into incubators.

Just spelling mistakes make sure to reread.
Suggestion
There is one part that seems pretty inconsistent, where it says, "We mixed tthese to create blue, uniform medias in each vial. Then we moved this vial to our ice bucket to sort the flies." Since you are talking about more than one vial in the first sentence, shouldn't you talk about all of the vials in the second sentence?
Suggestion
I would add commas so the sentences are broken up and aid in clarity, like in the second sentence, add a comma after "During this time..."
