Results of the germs experiment! June 14, 2012

I posted Monday that we were culturing germs on petri dishes as part of our FIAR unit on Madeline.  The results are in!

All 4 of our petri dishes, about 4 days after we cultured them.

Starting on the top row–this one is the foot one. The cleanest quadrant was Monkey’s on the top, then next to it is mine, on the bottom quadrant is Jedi (who had the most colorful germs), and then Bug’s (she was on antibiotics at the time, so I’m surprised she had many at all. 🙂 )

The other top row culture is antibacterial cream vs none–as you can see, there are a couple colonies in the “dirty” side and the antibiotic side is clear.

Directly underneath that dish is the toothpaste vs no toothpaste dish–you can see a ton of little white circular colonies on the side without toothpaste, and the side with toothpaste is clear (you can see the white streaks of toothpaste though. FWIW, it’s Dora the Explorer Colgate toothpaste. 🙂 It apparently kills germs. )

The last dish is the one we had the kids touch the sample on one side before washing their hands and again after washing with soap. It looks like we need to work on their handwashing skills because both sides had quite a few colonies on them.

This week, Monkey began using the curriculum Five in a Row.  We wanted to start with a familiar story (and, honestly, I waited too long to reserve Ping…I ended up trapped in the library’s waiting list for a couple weeks! LOL!)  So, we started with Madeline, and Monkey really enjoyed it (Bug did too…she ended up sitting in on Monkey’s lessons because she loves the story so much!).

We ended up doing most of the activities in the FIAR manual, but obviously I couldn’t take pictures of them all since a lot of it was verbal.  Here are a few pictures I was able to take from the unit though!

I found a copy of a coloring sheet of Madeline and her schoolmates. I printed it out, and Monkey colored all of the friends before cutting them out. Then she used them to practice her addition facts.

We also learned about ways to divide 12. The author divides the 12 little girls into 2 straight lines. We worked on what it would look like if there were 3, 4, and 6 straight lines.

The girls in Madeline also broke their bread every night. Bug and Monkey decided to make their own bread. Here, Monkey is cutting zucchini for zucchini bread.

Mixing the bread dough.

The final product–mini zucchini applesauce loaves.

At the end of the book, Miss Clavel says “Thank the Lord you are well”. We talked about germs and ways we can stay healthy. To reinforce the concept of germs, we took 4 agar-prepped petri dishes. In the first one, we touched half with our hands, and then touched it again after using soap to wash our hands. In the next dish, we swabbed the inside of our mouths and spread it all over the petri dish. Then in half, we spread some toothpaste to see if toothpaste kills germs in the mouth. The third dish, we swabbed our skin and put it all over the petri dish. Then in half, we used antibacterial cream. In the 4th dish, we split the dish into 4 parts. Each of us swabbed our feet and swiped the swab into one of the 4 quadrants to see which person has the germiest feet. 😉 Stay tuned a couple days until we find out the results (we have to let the dishes culture!)
