Both Lizzy and Sarah participated in the Science Fair this year with cute and interesting research. Lizzy wanted to find out which had a dirtier mouth, dogs or humans. She swabbed the mouths of 3 dogs and 3 humans. She took the swabs to the old hospital where the microbiology lab personnel taught her how to swab and preserve the petri dishes. She returned to the lab in 24 and 48 hours to check on and photograph the growth of bacteria in the petri dishes. The human mouths profoundly had more bacteria than the dogs mouths did. Emma's famous quote is, "Can you believe that my mom has a dirtier mouth than Kevin (family dog); and he eats poop and everything!". Sarah's research also involved dogs. She wanted to determine if dogs were more frequently right-pawed or left-pawed. She went around the neighborhood and asked the owners to shake paws with their dogs while she recorded which paw each dog shook with. She was glad to discover that 60% of the dogs were left-pawed. She was glad because she is left-handed! Sarah won 1st place for the firts grade in her school, qualifying her to go to the district science fair.
