The unchanged variables are the type of bread, the amount of water, the amount of dust.
In the experiment, dust the cotton swab and wipe it with three kinds of bread from three kinds of bread. Place a drop of water in each slice and place it in the Ziploc bag. Seal the bag and put it in a dark room
The average result of each independent variable is as follows. Multi grain bread grows fastest, then white bread, and finally wheat bread.
As a result, it was shown that the multipartite bread grows fastest, then the white bread, and finally the wheat bread grows.
The experimenter wants to know if the multigrain bread brand will affect mold growth.
Woke up in the morning to make a toast, did you know that your bread has a musty? What's wrong with buying this bread in the same store the same week? Shops, bread, what? We may provide information to help answer these questions. What happens if growth grows easier with different bread types? You can see if wheat, white, or multiparticulates grow faster.
The first one is multi grain bread. One of the many ingredients is oatmeal. Oatmeal contains a lot of oil such as nuts and the risk of mold is high. Delaying the drying process during the manufacture of the beads before you get it can cause mold. Yeast is a fungus, mold is a fungus. Yeast is almost every bread including multigrain bread. Because yeast is a fungus, it is susceptible to molds.
Second, wheat bread. It also contains yeast which make it very fungus. But wheat bread has salt. Salt can be used against Trichoderma, plus. Wheat bread contains olive oil and sometimes nuts. These are an important part of mold growth. Wheat bread has many ingredients that mold tends to grow, but salt can fight with some of them.
Finally, white bread. White powder contains sugar. Sugar can be used as a food for mold. When sugar is added to bread, molds can grow faster because of the strong supply of food. White bread also has yeast, fungus and mold related families. It is also a large food that contains lard or softener and can grow.
In other words, the multi-grain bread contains oats and nuts that are painted with enough oil to grow mold. Wheat bread also has oil, but salt helps fight them. White bread has sugar and lard, and large food producers use it for mold. All the breads contain yeast and allow them to continue to form but the other ingredients can maximize mold formation rate.
There is no better way to learn than the actual application of the science fair project. Students who participate in the science fair are given important life skills: The Science Fair provides presentation skills to students, stimulates confidence and belief, research-led exploration ability gives passion to competition, Open the door to infinite possibilities. As a graduate of the Science and Technology Expo, as a judge, as a volunteer, as a teacher, as a student to participate in the science fair for the first time, as a supporter of science, we know the importance of science and all science fields I will. We have saved our lives and the lives of the people we love with new renewable energy development and biomedical progress. We believe that it will be a better place for all of us to join the world, prosper across the border and create new technologies around the world.
Science fair is a commitment to celebrate science, technology, engineering and mathematics. Science fair encourages students to think about problems and opportunities in our lives. It challenges students to use scientific questions plus passion, innovation, and find ways to solve some of the world's most difficult problems. Every year, millions of high school students from all over the world are participating in the ISEF program - the world's most powerful STEM talent pipeline -. Currently there are thousands of diverse young women and men outstanding talent who have undergone scientific research and participate directly in the high level ISEF member science fair.
Science fair dates back to 1942, with William Emerson Ritter and Edward W. Scripps creating "scientific talent search" for high school students. The first National Science Fair was acquired by Alan J. Fletcher at the age of 18 and won in the form of the law of movement. In the United States, science fairs spread in the early 1950s. After the world witnessed the use of the first two nuclear weapons and the dawn of the television, interest in science reached new heights. Along with the development over the past decade, scientific stories in news such as Jonas Salk's polio vaccine and Sputnik's release released reality of science fiction and attracted more students to this exhibition.
