Microorganisms are very tiny living things, that are all around us, in the air, in our bodies and in water. They are so small that you need a microscope to see them. There are three types of microorganisms: viruses, bacteria and fungi.

Some microorganisms are harmful to us, but others are helpful. We decided to test how useful some microorganisms could be. The fungus yeast, is used to make the bread we eat everyday. How could we test how useful yeast is?
Watch the film below to see the bakers at work.
Meanwhile, can you explain what happened to the two types of bread we baked?
This was a great experience baking bread some people in class had yeast in thier bread and some did not but the one without yeast did not rise at all not even a little tint but the one with yeast was my one and it rose beacuse the sugar fed onto the yeast and thats what made it rise it was so delicious
ReplyDeletehi it is kayde. when we were bakeing the yeast made the bread raise but the on without yeaat did not raise. it was caused by co2.
ReplyDeleteone of these bread rise beacase it had yeast and the ather one haden rised. it rise beacuse it feed on the suger and grows and grows.
ReplyDeleteYeast is a type of fungi it feeds on sugar and realeses carbondaoxhade.Our table one did not rise because it had no yeast.
ReplyDeleteSpot on Fatima. Just shows how useful some microorganisms can be!
Deletewe tried to find out if bread will rise when we put yeast. You should always bake bread with yeast because the yeast feeds on the sugar which creates carbon dioxide.yeast is a type of fungus because if u mix yeast with sugar it creats gas
ReplyDeleteHi bloggers this was a great experience because we got to mbake cake and we could eat it.Although some of the bread did not rise :( Because some of the bread did not have yeast and the reason why it grew was because the yeast fed on the sugar.My groups bread came out looking like soggy cake and another groups had came out looking like bread from sainburys and tesco.
ReplyDeletethe reson why the yest ries insted of the namal flower is the yest breths cobidoxside and that helps it to grow
ReplyDeleteour focus was trying to find out how the bread ries and the yeast made it rise because ti fed on the sugar the carbon dioxide made it ver big and able to rise
ReplyDeleteTHANK YOU AND I ENJOYED OUR BREAD
One of the bread rised up because it had yeast and another my group didnt rised up because it had no yeast.The last group rised up because it had yeast and it ended up like real bread.
ReplyDeletei really enjoyed wirteing about the sinces project because we was testing peoples bodies and ours.
ReplyDeleteThe yeast is a type fungus and when we done the bread experiment the bread rose because the yeast was breathing out carbon dioxide.
ReplyDeleteYeast is a sort of fungi The yeast grown because we had fed it water but Yeast can not survive in cold water hot water only a ballanced temprature like warm water.
ReplyDeleteWell remembered Asheyden!
DeleteTHE BREAD WITH THE YEAST RISED BECAUSE THE SUGAR GOT MIXED WITH THE YEAST SO IT RISED ALSO IT HAD NO WHERE TO GO
ReplyDeleteHello everybody a few days ago my class tried to see if yeast makes bread dough rise but when you put yeast in bread dough it makes carbon dioxide which gets relased and turns into bubles.
ReplyDeleteThis day was such a fantastic fun day esspecialy when we got to need the bread it was of the hook
ReplyDeleteA microorganism that comprises either a single cell cell clusters, or multicellular relatively complex organisms. The study of microorganisms is called microbiology a subject that began with Anton van Leeuwenhoek's discovery of microorganisms in 1675, using a microscope of his own design.
ReplyDeleteMicroorganisms are very diverse; they include all of the prokaryotes, namely the bacteria and archaea; and various forms of eukaryote, comprising the protozoa, fungi, algae, microscopic plants (green algae), and animals such as rotifers and planarians. Some microbiologists also classify viruses as microorganisms, but others consider these as nonliving. Most microorganisms are unicellular (single-celled), but this is not universal, since some multicellular organisms are microscopic, while some unicellular protists and bacteria, like Thiomargarita namibiensis, are macroscopic and visible to the naked eye.
Microorganisms live in all parts of the biosphere where there is liquid water, including soil, hot springs, on the ocean floor, high in the atmosphere and deep inside rocks within the Earth's crust. Microorganisms are critical to nutrient recycling in ecosystems as they act as decomposers. As some microorganisms can fix nitrogen, they are a vital part of the nitrogen cycle, and recent studies indicate that airborne microbes may play a role in precipitation and weather.
Microbes are also exploited by people in biotechnology, both in traditional food and beverage preparation, and in modern technologies based on genetic engineering. However, pathogenic microbes are harmful, since they invade and grow within other organisms, causing diseases that kill humans, other animals and plants.
Super research Tobi. What do you think are the most useful microorganisms?
DeleteHi bloggers I just wanted to complet Miss Williams Task sice I wwas there.
ReplyDeleteYeast is a type of fungi that makes bread rise because when we was making bread we experimented if the yeast would rise and it did. It also feeds onto sugar that is what made it rise
Thanks for listening
Hey guys well yeast is a type of fungi that makes the bread rise and the process is actually based on yeast bye guys i hope you enjoy your christmas
