Question: What are some really cool/interesting Science Experiments that I can do at home?

I’ve tried the egg in the bottle, using matches experiment, the water into a glass using matches, and some others; all of which were great!

Any other cool experiments would be fun to try, Thanks!

Answer: I would suggest the following experiments:

1) Growing mold on a slice of old bread.
All you need for this is a slice of old bread, a plastic bag that can be sealed and a small amount of water.
Put the bread and a few teaspoons of water into a plastic bag and seal it. Place the bag in a dry/warm area and leave it there for several days to a week. Every day, check the bag. For the first few days, you can add a teaspoon of water (but don’t oversaturate it) if the bread seems dry. After a couple of days, you should start seeing mold growing on the bread. It may take several forms and different colors. (Once you see the mold growing, do not keep adding water.)

2) Demonstration of capillary action
You will need a celery stalk (or carnation), a tall glass, water, and food coloring.
Take either a celery stalk or a carnation (white flower is preferred). Place the plant material into a tall glass with colored water. Place this in the fridge. Check it every day. Within a few days, you should start to see colored lines (from the colored water) in the celery stalk or carnation. If you let the experiment continue for a while, the top of the celery stalk or carnation flowers should show some color.

Worlds coolest science experiment, to do at home!!!!

Question: ok guys i need help with a science experiment….:)?

ok guys…!I was given the three titles of the experiments that i could choose from for my Junior Cert and i cant figure one of them out..! the aim is to find out what is better for the plant, the food supplied with plants when you buy them or to two household items..which can be my choice..! I no exactly how to do the experiment I’m just not sure how to get y results..as in how do you measure which food is better..? i was planning on just seeing which one died first but that would take days and i have 2 do it all in 80 mins…!I’m not allowed add anything in..so it has to be something I see doesn’t it…?please help because its 25 percent of my grade…!:(
erm.. im in third year.. I’m in secondary school like..! Ive whatever equipment i need..:)

Answer: wat grade are u in… high school or wat??? what kind of equipment do u have???

Question: I need help on my science fair project.?

I already have a topic and already started the experiment, but I need a little help with writing my abstract and most of the other writing parts. I am comparing the amount of air particles in an open environment to a closed one. { I live in AZ so I am comparing if a dusty open field would have more air particles than a place with more trees and plants around.}
They are both near roads that arent too busy and probably dont get much pollution, but other things like dust, dirt , pollen, and seeds would affect those areas.
I could really use some advice, because its due on the 14th and all i need to do is the writing.

Answer: You are doing fine. You managed to convey to me what your project is about, so you already know how to communicate.

It is very useful to see how articles and descriptions are written and to learn some of the teminology that is used in your topic. I am linking you here to an article written about the same topic that you are examining. As a scientist/engineer I find the language in the article to be a little “journalistic”, but it is basically OK.

Perhaps it would be useful for you to print out the article and go through and underline all the technical terms. For example, you will find the following terms on the first page:

“particulate matter”
“airborne dust”

So the terminology for your “air particles” is more correctly expressed as “particulate matter” or “airborne dust”.

This is often the best way to learn how to do something – to read what is “out there” and to understand it. The objective of a science fair project is to teach you, and to help you to teach others. It is very frustrating when you have a hard time communicating, and nobody else can really do it for you. You learn how to communicate by absorbing the terminology into your own language “tool box”, then arranging your thoughts clearly so that others can understand.

You will do just fine. There is great joy in learning how to organize your thoughts clearly enough to express them to others. That is one of the things that makes a good scientist, and you are already on your way.

I was a science fair judge at one point. It was always terribly obvious when students were presenting words, thoughts and experiments that belonged to their parents or friends instead of themselves. I used to love the kids who had enough confidence and initiative to plunge forward and make their own mistakes and discoveries. Go for it!
