Question: Unique yeast science experiment?

Hi, I’m assigned to make up a simple lab about how yeast works in any context. I already know about the balloon experiment and changing the pH, different types of sugar, and temperature of water. Do you know anything different that I could do? What interesting characteristics could I test so I don’t do the same one as other people?

Answer: Well, I’m not sure if you can use this one but, yeast is needed in bread. In sourdough bread specifically, yeast from the air is used to give the bread its sour taste. You can capture yeast from the air by putting a bowl of flour and warm water mixture out. In five or six days, you should see bubbling, which is a sign that the yeast is growing. Maybe you can grow some yeast in different conditions, such as using salt water or adding sugar and then using the yeast to bake bread and see what the effects are.

Sorry if it sounds kind of dumb but reading you post gave me that idea! =]

Question: hi im looking for a great science website?

hi i love science all thing that are fasinating(things that work in front of your eyes) like insta snow crystals growing but i want to find a website that teaches me how to make this stuff with chemicals e.g borax
the sites im looking for are like free instructions to Science Experiments that arent for babies
baby experimens are like the easy to make pinwheels and colour wheels.”i dont want baby experiments”
teenager experiments are the ones im looking for.
