Default Daughter looking for High School Level Science fair projects

Hello,

My Daughter who is a Junior in High School is taking Chemistry GT this year. She is required to do a project for the science fair and is having trouble coming up with something creative/original. She has submitted ideas that weren't approved. The one I liked best was the effect of water temp on somebody trying to complete a task(such as unpacking and putting on a life jacket). We were going to use the pool and test the time it took to complete at cold vs warm temps along with some other variables time exposed etc. Well they told here this was not high school level. She has submitted 3 ideas all have been turned down. This is not my strong suit so struggling to come up with good ideas to help her.

Anybody have any good suggestions?

Do a survey on the chemophobia of the compound Di-hydrogen, Mono-oxide. The EPA wants to ban the compound because it is attributed to hundres of thousands of deaths each year. Lots of other really bad effects too on humans, automobiles, houses. The chemical especially targets the poor and under-privilaged.

Tell me to do a survey and try to get 100 people to sign the ban.

Glyphosate and negative effects on the human body...

I really like her first idea though. Wonder why it was shot down?

I always thought a project on the pesticide content of illegally imported street bought marijuana would be a very good project

who knows what they are spraying on that in Mexico and since there are no pesticide labels for marijuana the best you could hope for is they are using something approved for hops or hemp and following proper harvest intervals

but you know they are not

We wondered the same thing, only explanation she received was "Not High School Level"

Not many smoke mexican bud anymore but hopefully paraquat pot days are over... Sorry to detract from your post Irish Harmony....

Pretty sure Penn & Teller did that one already.

Here's a simple one for high school level.
http://www.webinnate.co.uk/science/week4.htm

Works best with filter paper, paper towel will do in a pinch. Try several different brands of felt-tip pens, all black. Sometimes you find the same ink is used by different vendors.

You can try water, vinegar and a mix of 1 part ammonia/9 parts water as the liquid for developing the papers. It will often make a big change in color patterns that develop.

Have her design and build a 12 volt AC for a cuddy cabin boat, 250 - 500 cubic feet.

Cooler that will hold a 20 lb block of ice.
12 volt pump - bilge, live-well etc.
5-15 feet of hose and a handful of clamps.
12 volt fan like from a computer. Or maybe a portable one from the beach section of Wally world.
5 feet of 1/4" or 3/8" malleable copper tubing to bend (carefully) into a radiator/heat exchanger.

Plumb the cooler, dunk a 20lb block of ice and enough water to prime the pump. Pump water from the cooler through the radiator and back to the cooler. Position the fan behind the radiator so that the cold air blows into the cabin. Get another battery. It doesn't even have to be in a boat, a garden shed would do, as would a van.

Experiments could be done on delta temp, battery duration, ice duration etc.

When the Fair is over, ship the gadget to me for installation in my vessel.

galvanic corrosion...fresh and slat water..multiple tanks with and without sacrificial protection and voltage readings to confirm the movement of electrons....

She could do something comparing coolers or insulation materials.

The winners in my local high school science fairs, always mention "global warming". Just say whatever she decides on is for global warming, and she will win.

you can do this with dry ice also

Here are a few pictures of a project my Grandson made for one of his classes. He is a Jr. in high School, they liked it so much they are putting it in a Senior class contest. He can not compete in the contest, they just want to show it. He did all the bending and welding himself. He and his Dad are bulding a VW baja, They have a ways to go before it is finished, I will post it pretty soon in a new post. I did not take very good pictures

I dont have any idea for you daughter, but I know she will make you proud

This may be a little too basic, but my son (11 YO) cam home and said he has to do a science project. His idea was to convert heat into electricity. I already designed the two heat sinks needed (small power stearing coolers), will run chilled watger through one and heated water through the other. Chilled water will represent the water temperature coming from coils that run through the earth and the heated water will represent water heated via solar. Also found mini 3 amp pumps on line for the chilled water and will allow the laws of physics to circulate the heated water (may be able to use physics for this chilled water as well, just not sure).

In the end we will spend about $150 and will be able to produce up to 3 amps at 15 volts times 3 Peltier Thermo Electric couplers for a total of close to 10 amps. Actually seems quite a bit more efficient than solar electric.

If interested, I can PM you what we are using for the radiators/heat sinks. And anything "green" is huge with the schools. She could take it up a notch and actually build a small solar collector for the heated water.
