Question

How to grow bacteria?

Answer 1

Hey there! Now that I know its for your science project , Id be more than  happy to help ( if this was from your text book, It might have not been right since some text books might not mention the method I would have given you)

Sooo.. Here we go.. For my science project This is the method I used...

step 1 ) Go to your fridge 
step 2) Go grab a piece or two of white or wheat toast. Its preferable to use both so you can see and compare the difference.
step 3) (before you do anything else, since it is a science project, your teacher might want a hypothesis, with observations and data, and a conclusion to your experiment, so just make sure you have those done if you have to.)
Step 4) go get 2 Ziplock bags, preferably the one that you zip and seal..
Step 5) Place the wheat toast in one bag, and place the other toast in the other bag...
Step 6) Make sure that when you put the toast in the bags , you take all the air out of the bag, make sure there is no air at all!
Step 7) put the toasts in a dark place with no light and very little air. The place I put them was the closet that I never opened. 
Step 8) Leave them there for about 7-9 days 
Step 9) Take it out... 
The results are going to be gross... you should see weird fuzzy things (mold,fungus, bacteria, etc.)
Thats when your project is complete..

PLEASE DO NOT TOUCH OR EAT THE TOAST.. WHERE PLASTIC GLOVES WHILE HANDLING THE TOAST, BECAUSE IT CAN GET YOU SERIOUSLY SICK!!!! DISPOSE OF IT AFTER YOU ARE DONE! THANK YOU!
