Science project ideas?

[RS3]

Need some ideas for a 5th grade science project. Any suggestions?

[Reckless Cheri]

OMG ... I remember those days. I can honestly say I don't miss science fair projects. LOL
I will ask my girls what they did and let you know.

do a search on google there are a lot of websites just about science projects and some great ideas we did one last year about which gum's flavor last longer. You don't want to do that one unless you have good dental insurance and never want to see a stick of gum in your life.

Showing how heat rises. Take two containers with room temp water. Pour in scalding hot water (dye it red for a better effect) and watch it rise.
Take ice cold water (dye it blue) and pour it in the other and watch the results.

Or you could do the classic, styrofoam ball Solar System!! That's never been done before

you could test the effects of a razor blade on a stick flying @300plus FPS

grow mold

Buy different types of loaves of bread. Put them in different enviorments and predict which will mold faster or not mold at all. Easy!!!! Inexpensive!!!
Won many a science fair on that one. email me and I'll give ya more info

Here are some ideas from a quick search:

LOL

Be sure and compare sharp razor blades vs. dull razor blades

I remember doing one on bullet trajectory and ballistics but these days that would probably get you sent to alternative school...

One of the best science projects I did was an "oil well". You take one of the large clear water service jugs (Ozarka/Culligan style). You fill it with various layers of substrate (sand, gravel, dirt, etc). Then you take some cooking oil and layer in your "oil". You run two glass tubes through a large rubber plug in the top down into your "oil". If you hook up a manual bicycle pump to one of the tubes, it will pump the oil out of the "well". It was quite informative when additional information about oil production was included. Not to mention it cost about $20 to make.

I also used a dog heart with a serious case of heart worms for a project on canine diseases. It was quite the prop back in the 80's.

Hydro electricity is what my oldest did his on on the 5th grade.

We toured a dam and he researched more information about it.
Then I helped him build a "city" on a 3' X 3' plywood. A dam with a electric motor (operated off a 9v battery) small gauage wires on dowel rods (make untility poles) and LEDs make the lights...

Prettry cool and he won first place with it.

Solar Electricity would be a good one too.

you could do a timeline study on how long it takes the average woman to gain 35 lbs after the honeymoon is over.

LOL

Be sure and compare sharp razor blades vs. dull razor blades

and sharp deer opposed to dull deer!

Solar Electricity would be a good one too.

Yeah do Solar. Find a way to use a feeder motor and a solar panel, then you can have some use for it after the project.

Experiments with liquid nitrogen, write up about how cold it is, how it's made, etc.

Show how to condense the vapor in your breath. Fill up a ballon, tie it off. Get liquid nitrogen at a gas supply store, pour into a metal bowl (yes). Rotate the balloon, as it shrinks (gas volume decreases with temp), water vapor liquifies. Put an onion in it, then remove with kitchen tongs and smash with a hammer. Lots of other fun things. The neighbor's problem cat is not a good idea for the school project.
