Oak Meadow Science is very hands-on. The kids and I really appreciate that. Science is so much more meaningful when you can see and touch it.
Here are just a few photos of some of our science activities from the past few weeks.
The kiddos are gathering pond water for our observation of bacteria growth. We put tap water, pool water and pond water in petri dishes with agar to see which would grow the most bacteria. The children's hypothesis was that the pond water would grow more bacteria. They were right, of course. You'll have to take my word for it because I forgot to take pictures of the bacteria growth.
Since I had extra petri dishes and agar, we decided to swab some things around the house to see what kind of bacteria we could grow. We swabbed the toilet seat, the door handle in the bathroom, the coffee maker handle, the computer keyboard, Thing 4's bear that she has slept with (and chewed on) since she was 6 months old (aptly named "Yucky Bear Bear" by her brothers), and Thing 3, who had a bad cold at the time, coughed in one of the dishes. Ick.
Here, the kiddos are looking at Thing 4's blood. She made good use of the nasty scrapes she had on her knees after having a bad fall on her skates.
