In these days we are studying microorganisms in our classes. Bacteria are the most abundant living beings all over the planet and we can find them everywhere. Today we are going to confirm it. At our laboratory, we have prepared some Petri dishes with culture medium, and we have put different objects over it: our fingers, different plant leaves, our keys, ear rings... We have even sung a song to a Petri dish. Tomorrow we will see our results. If bacteria are everywhere, we will expect that our bacteria grow. In this case we will see lot of colonies of different sizes, colors and shapes. Perhaps we will have some fungi. I would like to know your opinion about our experiments. I know that some of you want to repeat these experiments at home. I have some Petri dishes for the best comments.
Today's class has been very fun. Today we have given the plates of bacteria, different objects such as hairs, keys, plants, coins, saliva ... And even talk and sing. I have made some of the objects that I have announced before, such as hairs, keys and coins. It has been amazing! -Elisabeth-
ResponderEliminarHi, teacher! I'm Almu!
ResponderEliminarI like this experiment so much! I could see how Noa put his finger and then his mark was marked, as well as the trace of the earrings, the leaves, the flower, the coin, the keys, the land of the garden, the saliva of Maribel ... I am anxious to see the result and observe the bacterial colonies!
Hi techer I was loking on internet somes photos aboy bacterias colonies. Their´re amazing! I hope that our bacterias look the same or better. I was enjoy with that great experience and I love to participate on it.
ResponderEliminarI was lookin on internet for other types of culture ther are:
ResponderEliminar-Fitration (is only used whe are a little number of bacterias)
-Most Probable Number (this is a technique statistics)
-Microscope (you take the bacterias and see in the microscope)
There are other method, but this are the more popular.
Hello!My name it´s Sami.Wow,¡ It´s amazing!Today we put some things like flowers,ground,hair,coins,pencil,etc,in a petri dish,there ( in a petri dish ) are culture medium,we put all that things on the culture medium,and we are waiting for tomorrow,because today and this night,ther are goin to grow some bacterias,and some people are going to take another petri dish to their houses to do the same experiment with other or the same things.Good bye!
ResponderEliminarHi teacher I’m NOA
ResponderEliminarI really liked this experiment because it has been very interesting and fun.
I would like to take a petri dish because I would like to experiment with the cultivation of bacteria.
Hello teacher! i'm very excited with this experiment. I tink is very interesting, I really want to see the bacterias in the petri dishes with the microscope, must be very nice and extravagant. I love everything related to bacteria and microbiology, because I think it's something very interesting and nice to know.
ResponderEliminarHi teacher! I’m Laura. Today we started to mqke some bacterias colonies. At first Noa vive su some vocabulario from bacterias and then we Putin in the culture medium a fingir princesa. We put hair, flowers, plants.... too. In other petri disk we put once key, in an other once we put cash and sing the y too!!!. This experiment is very interesting and funny. 🦠 🧫🤩
ResponderEliminarHello teacher! I’m Laura again. I’m very excited to see the colonies tomorrow!. But I have a question, tomorrow we look the colonies at class or in the break at 11.15a.m?
ResponderEliminarThe wednesday the biologie class we workto bacterias and petri dish. We put in the petri dish different objects , for example: finger pink, hair, keys... I put my saliba in the petri dish with a stick, What will be the result? I do not know! Teacher thanks for this class is very interesting and fun.
ResponderEliminarHello I am laila of three project talks about the bacteria we took the Petri dish and we threw many things: clock a nail nails a flower we were going to take the phone from Medi but it could not fit the saliva of a partner ect. this experiment is very interesting because as matter can be the last year we did an experiment like that and we needed a million bacteria to see a millimeter had to be in a row
ResponderEliminarhello, I, am Kiara.
ResponderEliminarin high school, I went to the laboratory and my teacher told us about the bacteria. It had a plaque of bacteria, and when you anything, it forms a cell. a partner put her finger inside the plaque, then we put hair, some coins and keys, the saliva of partner, algo land and finally fertilizer. I would like the know what happen in a few days.
Hello,I am Patricia. This experience I liked a lot, I would like to take a plate to experience the bacteria and learn more about them. in the class we put hairs, flowers, keys ...
ResponderEliminarHello, I'm Julia. The experiment is amazing. We preparated some petri dish and we put different objects like: fingers, plants, rings ... Before we see the result.
ResponderEliminarteacher, this is the message you are waiting about the petri dish. The form about the bacterias grow up is impresionant, i want to have a petri dish teacher i think this message are very good, what do you think?
