After collecting the pond water and adding the food source, we let the jars sit for five or six days. Now it is time to have a look at what was growing inside.
The first culture the students decided to look at was the one with the egg. They open the container and turned up their noses. Notice there are no windows in our classroom.
After the initial shock of the smell, the students were able to collect a sample.
Then place a drop on the slide. It looked as bad as it smelled. lol
The purpose of this experiment was to try to locate several types of bacteria and possibly identify them. Here is a photo of what we saw.
We were able to isolate some of the bacteria and identify them, but I wasn’t able to get photos. We did see a great volvox.
The other cultures did not smell any better than the egg. View what happened with they opened the bottle with the rice food source.
Kind of makes you want to hurl, doesn’t it? 😀
This completes our Module 2. Next week we begin Module 3 and study the Kingdome Protesta.
