Tuesday, the students in my Biology class, brought their pond cultures they collected the week before. This is what my samples looked liked. The water had been “stewing” for five days. You really can’t see the different. I think it was the egg jar that you see foaming here.
Let me tell you, this smell was worse than last year! I thought one young man needed to leave the room, but he kept saying he was fine. He looked very green to me. Most of the time the kids had their noses covered. lol
Each jar was to be opened and some culture (pond bacteria) was taken out with an eyedropper. Six jars opened at one time, made the room smell lovely.
A drop of the culture is placed on a clean slide and then covered with a cover slip. To learn how to prepare a wet slide, please read here.
Notice where this young lady’s hand is. Over her nose! 😀
The smell was bad; really really, bad. Next thing to do is observe under the microscope. See the girl on the left? She was in my class last year, came in for a visit, and then participated.
It was a great day, smell and all! 🙂
