Science Fair Questions about Bleach & Molds

Q: What concentration of bleach is use to kill mold?
Amber
A: This site is all about teaching you how to find the answers yourself. So lets begin there: In the google search window input the keywords, “concentration of bleach to kill molds” and whala – tons of answers.
From my search I found out that 10% of bleach to 90% water is the standard answer.
Now what comes to mind is how safe is it to use bleach? Bleach is toxic. And when exposed to molds, molds break the immune system down. Based on this information I would choose another project.
Then, what’s the next step? Do another search. This time I would put it Google Search, natural way to kill mold. The answer comes up at the top of the page in a box.
You will also see another keyword that you can use. I am not going to tell you what it is. When you find it you can substitute the word, natural, for this other word.
To find outstanding science fair projects begin here…
Building in 1 Direction: The rods can be connected in-line without the intermediate need of a connector, almost reducing to half the quantity of parts required to build models.
Building in 2 Direction: While the assembled rod looks uniform with nothing protruding, it may provide building directions vertically and sideways by simply snap fitting another rod to one of the bi-directional side cavities. This innovative design allows snap assembly on both sides simultaneously and greatly enhances the expandability of the System.
Building in 3 Directions: The System is capable of tackling with the same ease as all the other building directions. All directions of the 3D space are accessible by combining the rods with the various types of connectors.
Connecting in Fixed Angles: This system makes it possible to build complex models that require connections of 45°
Building Machines: The optimized design of Engino components consists of only 18 different types of multi-functional parts. Yet you can build simple and complex machines. Following the same design principles of the basic system, a range of different types of gears, pulleys, axles and accessories make it the ideal constructional toy for home and school.
I am not recommending to do this project because (as stated above) bleach is toxic when you breathe it in. So everyone in your household would be affected.
I suggest doing another project. There a a lot of science fair project ideas throughout the website. Why don’t you choose from these fun kids science fair projects? Here you will find yukie, gooey, gookey or slimey science fair projects and kits!
heyy thx for the reply. i am going to do a different science project but my teacher said that it has to be a question that has sumthinn to do wit dpendent variable and independent lol so if u canhelp mee that would be great if u dun mnd me askinn how old r u ?
All science fair projects have to do with dependent and independent variables. Go to science project ideas, follow all the steps to do a complete science fair project. This page will lead you to other pages for the 6 steps of the scientific method.
I will not give you a science fair project, this is your assignment.

PS: When you are writing in the blog, I would appreciate you using correct spelling.
The reason we ask you to write with proper grammar and spelling is that this is an educational site that’s viewed all over the world and not everyone can understand what you wrote. And on top of that we have very high standards. So thanks for asking.
Now are all your questions answered?.
okay I understand. thank you.
I think that the 10% bleach solution is something that is used in most clinical environments to disinfect, is that right?
I like to use rubbing alcohol to kill mold myself. I find i have better results and it dries out the mold not like bleach and water can spread it sometimes.
10% is the standard, but be sure not to inhale the fumes.
What are you referring to when you say that 10% is the standard?
I would choose another project as well. I use nothing but green cleaning products in my line of work so I try to stay away from bleach at all times. Thanks for the great information.
I think that the 10% bleach solution is something that is used in most clinical environments to disinfect, am I right?
I prefer other projects as well. 10% bleach seem not enough to kill all the molds and assure that they won’t come back.
Sunshine is correct, when writing in blogs always use the correct spelling and do not practice text speak.
Why not formulate a science project from what held you back from using the bleach? Try to find another formulation that is not harmful to one’s health, and yet, can still kill molds. Your project will be more meaningful this way.
