Help! Buying Prepared Nutrient Agar in Disposable Sterile Plates

[Wildiris]

I am buying 10 prepared petri dishes for DD~7 to do a bacteria experiment in Singapore Science, but I am going to have extra dishes.

(How do I store these when I get 'em?)

 

Any ideas for what we could do with the other 7 dishes? I'd love to do a science fair type project with DD, but I am not a science person. I need some help.

 

Any and all suggestions welcome.

 

Thanks,

Iris

I don't know how to store them, but I know on Mythbusters they did an experiment to see if that myth about toilet spray (you know - when you flush, anything within 6 feet of the toilet is getting poo on it) was true. They swabbed several areas of the bathroom and then a couple areas of the kitchen to see which had more fecal bacteria.

 

editing to add: this is one of those experiments that would be fun to do, but you might not want to know the results. KWIM?

Thanks amey311~

 

I'm sure this would be an eye opening experience for the whole family.:tongue_smilie:

Do you know where I could find more information on doing this experiment?

 

Thanks,

We had my brother press his fingers in one plate after going to the bathroom & washing his hands, and another after using the bathroom & not washing his hands. It was grooooooss :lol:

 

You could also swab cheeks & see what lives in your mouth.

We did many household surfaces when I did a unit on bacteria. Door handles, computer keyboards, toilet seats, phones, kitchen countertops, and someone's hands. I did this as part of our science club and it took every bit of self-restraint to not bleach everything before everyone came. I just did my normal cleaning.
