What experiment could i do for science?

Question

I need to make up an experiment for science and do it. I am not sure about what i could do that hasn't already been chosen and isn't to hard.

I will need to do some research about the experiment.

Some things that other people are doing is:

What makes flowers stay freshest?

What sports drink works best?

Who has a faster reaction? Male or Female?

And BTW.. If this helps i am 14 so make it something suitable and also not too exspensive

Answer 1

here are some ideas and i hope they helped..

1- Which soft drink is the best, in healthiness.

2-Which form of transportation is most commenly used around the world.

3-Which car is the most used in the world.

4-Which beach has some of the worlds rarest sea shells.

5-Why do girls like pink, and where as boys prefer blue?is it natural or due to traditions.

6-why do cars are said to be boys stuff and dolls to be girls stuff? tradition or in nature.

regards

Very simple science fair projects often get overlooked by judges, and are given a low grade because of them being simple. If your 14, then you should choose something more advanced than the projects listed. Science fair judges and your science teacher like to see science experiments that cover a large area of information... being too specific, especially on a simple subject, lowers your grade. Out of the projects listed, I would have to go with the reaction time. That one can be fairly advanced with you work with it. By this I mean you have to cover WHY one has better reflexes than the other. And even then it is pretty simple.

Before choosing a science fair project, you should pick a topic you enjoy the most about science such as physics, biology, chemistry or geology, and base your science fair project on this subject. Choose a project that involves multiple variables, and is of the appropriate dificulty for your grade level and your understanding of science. If you love science and are good at it, then choose an advanced project but if you hate science, choose one that matches your grade level and doesn't go above it.

Some of the best topics to do a simple, yet interesting science fair project on would be either biology or physics because there are many cheap, yet interesting experiments to do on these subjects.

Good luck in science.

I was reading this article on fruit ripening from http://chemistry.about.com/b/2007/05/10/...

Fruits rot because of mold and bacteria and also the release of ethylene which hastens the ripening process.  A question to ask is which contributes most to fruit rotting? Mold and bacteria or ethylene release?  You can do some research on mold and bacteria and on the biochemical process of ethylene oxide and ripening.  Then you can come up with a hypothesis as to which one it is.  Something to consider from the article is that putting a really ripe apple in a bag with an unripe fruit will cause the unripe fruit to ripen faster.  This is because of the ethylene.  You could demonstrate the specific effects of ethylene by doing that along with a control fruit(of the same type and ripeness) in a bag by itself and another one outside a bag both by itself and with a ripened fruit.  The article suggests using iodine to assess starch levels; unripe fruit should have more starch and stains darker.  Any rotted fruit that still has a lot of starch therefore has to be a consequence of mold and bacteria. I'm assuming the bacteria and mold would preferentially metabolize the sugar over the starch.   I guess you would be able to visually see the mold and bacteria accumulation after a while.  On the down side it might take a while to rot a bunch of fruits; bananas go pretty quick though.
