HELP ME IF u know about science?

Question

okay i have to do science fair but my topic was too childish.

i was gonna do my project on if the type and hardness of bread affects the rate atwhich it molds.

however this topic is too easy and i need another one how can i expand on this topic or can u think of a similar one?

Answer 1

1) Measure the growth rate of mold on each type of bread

2) Set out each type of bread out at room temperature, in the fridge, and in the freezer, to see how temperature affects growth.

3)Also, you can test for the number of individual colonies as well as how much each colony grows.

4)Put each type of bread in different containers and compare the time it takes for mold to grow. Also compare with bread left out in the open and at room temperature.'

Lots of variables you can use. Good luck.

Answer 2

how about determining what types of bread made with what types of grains mold easier. As well as the moisture content and time needed.

Answer 3

Try to grow a variety of bread molds and study them. Penicillin is the only form of bread mold. I have noticed that you location can also effect the time it takes bread to mold. In Texas it takes more time for bread to mold than it does in Virginia, even when stored in identical packaging. Why, I don't know; it is probably because there is as species of bread mold that is more common in Virginia and more able to infect the bread.

Or you could study different types of bread; see this article: http://en.wikipedia.org/wiki/Bread#Bacterial_leavening
How are they made and what the differences are between each culture and region.

Then there is the historical discovery of penicillin: http://en.wikipedia.org/wiki/Penicillin
“The discovery of penicillin is usually attributed to Scottish scientist Sir Alexander Fleming in 1928, though others had earlier noted the antibacterial effects of Penicillium. The development of penicillin for use as a medicine is attributed to the Australian Nobel Laureate Howard Walter Florey. In March 2000, doctors of the San Juan de Dios Hospital in San Jose (Costa Rica) published manuscripts belonging to the Costa Rican scientist and medical doctor Clodomiro (Clorito) Picado Twight (1887-1944). The manuscripts explained Picado's experiences between 1915 and 1927 about the inhibitory actions of the fungi of genera Penic. Apparently Clorito Picado had reported his discovery to the Paris Academy of Sciences in Paris, yet did not patent it, even though his investigation had started years before Fleming's. Fleming, at his laboratory in St. Mary's Hospital (now one of Imperial College's teaching hospitals) in London, noticed a halo of inhibition of bacterial growth around a contaminant blue-green mold Staphylococcus plate culture. Fleming concluded that the mold was releasing a substance that was inhibiting bacterial growth and lysing the bacteria. He grew a pure culture of the mold and discovered that it was a Penicillium mold, now known to be Penicillium notatum. Fleming coined the term "penicillin" to describe the filtrate of a broth culture of the Penicillium mold. Even in these early stages, penicillin was found to be most effective against Gram-positive bacteria, and ineffective against Gram-negative organisms and fungi. “

Just like the telephone Alexander Graham Bell wasn’t the only inventor working on it, but he ended up getting the credit, even though eventually he lost the patent.

You could probably find a drug supplier or tissue supplier who could sell you penicillum mold for experimentation. That would be an interesting project in itself and could be included as part of the project.

You could study the evolution of the war against bread mold. Newspaper wrapping was probably the first method, but modern chemicals are added to the bread to keep it from molding. A tour of a bread factory, with a camera, would be in line here. You can talk with the factory representatives to see what they do. If you use there brand name, there bread, and give them a good report then they will want to help you for the free advertising you will give them. Most large cities have a commercial bakery near by. You can also talk with other bakers, especially those that make their own bread and see what they do. Most use kits bought from companies like Cisco, so you might want to write them for an interview by email.

How is bread graded in the manufacture process? What is done to make different types of bread? All of these topics could come out of that company tour.

Bread is a fairly lame subject so you want to include the evolution of the idea. First you will want to concentrate briefly on the history. Bread was a major key to the Egyptian civilization and the pyramids would have been impossible with it. Bread is our first processes food and it is still used today and widely popular; what child doesn’t have bread? How did the industry develop and grow?

How does industry use bread? Pizza bread is different than the buns for Big Macs, which is different than the bread supplied to resturants.

Then you could leave bread entirely and look at mold and what other molds make useful scientific products. You could study the new field of extremeavores where scientists are looking for bacteria from Yellowstone Hot Springs, the volcanic underwater sea vents, and those that live in acid caves or deep in caves with no life. Scientists are looking for new drugs and other medicines produced naturally by these new type of bacteria. This is revolutionary field of science and is on the forefront of the drug industry; because they could find the next cure for cancer.

What other types of molds are there? Are there any that are also useful or helpful to mankind? There is a toxic pool of waste at a copper mine that is being studied because of the new bacteria that evolved to live there. One species was traced to a migration of geese that stopped by the pit.

Your chosen topic; bread; mold or bread mold is a limited one so your report will have to be comprehensive, and cover the history and development as well as the topic itself. The history of science is just as important as the science, because it is important to know how something was discovered as well as how its use has evolved. That means you will probably touch on the Earl of Sandwich; the creator of the sandwich, the first full course portable meal and the start of the fast food industry.

Expand your topic and then pick an area and narrow in on it. That is how science works. The traditional way is to pose a question and seek the answer, but that requires new research. A report on the development and use of a product can be just as valuable as new research, provided you uncover new information that most people don't know. Like that most grocery stores get their bread from the company Cisco in premade dough that only needs to be cooked.
