This is little offtopic but I dont have access to other forums now... My little cousin of grade 4 wants me to give an idea for his sci project. Can anyone give a project idea for a "simple", easy to make in less time, for a 4th grade student? I googled for sci projects but almost all of them belong to 7th or upper grades.

So many things they can do. Telescopes, water or air rockets, kites, little solar-powered cars, little mechanical robots, ...

hmmm... ***...remembering my approximately 4th grade "sci projects" i did at summer( when i was 10 or less )....like attempt to collect some metane from pool to the plastic bottle, mix with 15 parts of air (air have 1/5 of oxygen, and to oxidize metane you need 3 molecules of oxygen per molecule of metane(2 for C and 2 for 4H)) , and blow up...*** heh. not very scientific(except calculation how many air needed to fully oxidize for maximal effect(i really did that calculations)), and pretty dangerous.

Maybe, making a gigrometer from 2 termometers(one wet,one dry)?

Or something with electricity from friction of plastic For instance, piece of plexiglass placed above table(say, with books under corners) and small pieces of aluminium foil inbetween . When you electrize the plastic using cotton, pieces of aluminium foil will start to jump up and down :) (have you did that?).

it's hard to find something "sci" that avg. 4th grade elementary _teacher_ can understand, that's the problem. It would be good if your cousin will be interested in science after that project, and so, make sure teacher is not a stupid "i-know-better" kind of looser (thanks God i had good teacher, but i knew some "i-know-better" ones).
also,7th grade sci projects you can find in internet is simple enough for 4th grade.

I'll allow it, since is kind of a brainstorming question, not a "hey give me the answer" question. Could get some more interesting responses.

My 4th grade science fair project was to leave 4 pieces of bread in my pantry and see which one would be most hospitable to fungal growth. One piece of bread was left on a plate and dry. The second piece was doused in water, but left oncovered. The third piece was sealed in a bag and the fourth was doused in water, then sealed in a bag.

MrPoopypants: nice :-)
and i guess first was 4th , but maybe(inprobable) 3rd. it's need to do many tests(kinda fingus[sp] rally) and find what scored higher :)....

I apologize for each word being capatilized, but that is how it was in the book, and I was typing without looking at the screen :P
I cannot guarantee all of these are for 4th graders, or that they are prize winning. Espicially since my school didn't have science fairs. :(

A minimal calculator in QBasic?
Or perhaps a program in LOGO?
Try and figure out AND/OR/NOT circuits using water perhaps?
(See pattern in the stone book for the idea)
