Question

any ideas would be appreciated. preferabbly in engineering but any ideas are help ful. plz dont just tell me a link bacause they all jst lead to more links. i need help that i can understand and i dont want to keep going from link to link in a circle. i really need help. thank you

Answer 1

Which colored nail polish dries faster/slower than (a color, like red, or black...or whatever you'd like)?
Which brand of paper towel absorbs more water?
Which brand of popcorn pops the most kernels?
Which brand of nail polish is better than (cosmetic brand, like Revlon)?
Does salt water freeze faster than tap water? (or vice-versa)

Answer 2

Sit down with your partner.

Each make a list of 5 things that you lwould like to learn
more about: chemicals, buildings, bridges, space flight,
food making, biology, ..anything really can be approached
from a scientific method.

See it you have anything in common in your lists.

If you do, say food making....pick out some way to:

1. List your preliminary observations on the topic
2. See if there is anything that strikes your fancy
3. Figure out a way to test the idea

Alternatively:

Just put candles in different sized jars, close them, measure the time to go out. Explain why they go out at different times.
Study fire. Gases. chemistry.

Or.

Come up with a questionaire to ask people different
questions. Catalogue the answers. Use your computer
to generate Statistics on theanswers. Could be anything
from popular culture to politics. Define the various
statistical terms.

or

Grow plants in diffeerent environments.

or

Figure out a way to test how fast sun block washes off, or
nail polish wears off, or food spoils in the sun, or....again
the list goes on.

Main thing...pick something you can have fun with...or you'll
get bored and not do a good job.

Answer 3

A science project should involve comparison of different entities, which could be the same item at different times or two (or more) different items. The project should be long enough that it takes longer than a few minutes, but short enough to hold the interest of the experimenter.

The ideal subject for meeting these criteria is RADISH SEEDS! Initial results can be noted in two or three days, the experiment can be as simple or as complex as the researcher desires, and the final results can be shared with a class... or eaten!

Growing medium:
simple... outside in the soil
medium... inside, in pots (boxes, cartons) filled with garden soil
complex... containers filled with sand (no nutritive value) with added elements

Growing conditions:
simple... outside with a box covering some plants to control light
medium... inside with several covers to allow different amounts of light to hit different plants
complex... differences in light amount & type (sun or artificial), heat, humidity (wrapped in plastic to keep moisture)

Moisture:
simple... outside, water some more than others
medium... inside, water daily or every other day
complex... apply water to soil only, apply water to soil and leaves, mist leaves only with little water to soil

Nutrients:
simple... outside, add some fertilizer to some
medium... inside, add different items (fertilizer, (coffee grounds, etc) to soil
complex... add different elements (nitrogen, phosphorus, etc) alone or in different combinations and concentrations

In other words, these simple seeds can provide opportunities for scientific investigations for every age from preschoolers (who may simply plant and watch) to PhDs doing advanced research. This may eventually be extended to other plants and create a lifelong interest in botany.

I'd still be doing my own studies of these seeds, but radishes make me burp! LOL

Answer 5

U can make a bulb glow by using potatoes...
and if u ask my experience i did a science fair project on WHICH GUM WILL LAST THE LONGEST? i bought chewing gums of different companys ( same flavor) and then got my friend to chew them one by one and recorded time when the flavor was gone. It was crazy! though try making it more interesting....
hope i helped!

Answer 6

Maybe try building a solar car, you could probably find some websites that have some information on it and you could probably find what you need at a local hardware store.

Answer 7

i must say i am not the best to answer this, but do something easy. My friend and I tested the quality of brands of baby diapers for our science fair project (like we used off brands and stuff)- you could do this with paper towels or something

Answer 8

you can build a bridge out of toothpicks or popsicile sticks.. test the weight of it by placing books on top..

Answer 9

Make a robot that plays soccer.

Answer 10

try detergent tests . stain towels with ketchup, chocolate, lipstick ex. and wash them with different detergents example - tide, oxieclean...
