Bacteria Experiments




I am science geek. My major in college was Biology so I was so excited when I got to start doing science lab with the kids up at co-op! With the flu season upon us and everyone in a panic about H1N1 I decided that this would be a great week to talk about bacteria. So we ordered kits from http://www.homesciencetools.com/ to grow our own bacteria. We swabbed and cultured 20 samples last Wed and patiently have waited for them to grow. We had major success and the process has resulted in my BOYS(!) constantly asking to wash their hands. I definitely consider that a result! Above are a few pictures from some of our best cultures, including a water fountain, a computer keyboard and hands that had been coughed on(I know totally gross right?!).


Everyone up at co-op was so excited to see this, that we have decided to order a gram stain kit to see what kind of bacteria was growing and you can be sure that we will be making sure to disinfect the areas that we found the growth in.


I recommend this kit for all ages. Even my k-5 daughter understood what we were doing and it really gave her a visual for why we need to take special care not to spread our germs.


http://www.currclick.com/ has some health units that would suppliment this experiment nicely.

If you decide to do this experiment please take precautions and use safety glasses and masks. Remember thats bacteria thats growing in there and it can make you sick!

This is awesome, and really gives the kids something to think about! Just telling them why they need to be clean, wash hands, use tissues, etc., doesn't sink in the way SHOWING them does.
