Science Fair Project - Growing Bacteria Day 2

As I said yesterday, my 9 year old is collecting data as part of her science fair project.  She's testing bacterial growth from several different sources.  After 12 hours there wasn't much to see, but the next morning, approximately 24 hours after starting, there was quite a bit to see!  It was quite a surprise for her to wake up the next morning and find several colonies of bacteria growing!

Left:  Bathroom sink.  Middle:  6 year old's mouth.  Right:  Floor

Left:  Dirty Cell Phone.  Middle:  Clean Cell Phone.  Right:  Dirty Cell Phone with Anti-Bacterial soap added

Left:  Doorknob.  Middle:  Control dish with no bacteria added.  Right:  Keyboard

Check out that growth from the bathroom sink!  Wow!  The mouth has quite a bit of growth too and just a bit from the floor.  Not much from any of the cell phone swabs yet nor anything from the doorknob or keyboard.  So far so good!  Can't wait to see what Day 3 has in store for us!
