Find HC a Science Project! (in Contests)

500k to the person who finds me the best science project for my little brother (2nd grade)

It should follow these circumstances:

1.) Easy to make
2.) Stuff found laying around the house... i don't want to go buy some high powered magnet the size of a quarter....
3.) Around k-5 Level of difficulty

So yea...find me something easy that i help my little brother make for his science project...

its due wednesday...so i'll keep this open till sometime sunday

I found this on a forum.

Last year my son won 1st place with Which Soap Works Best

1) buy 2 diffrent soaps
2)Have 2 cotten balls with alcohol on them
3)get 2 Zip lock bags
4)Have your child play in the dirt
5)wash hands with 1 soap (count to 50)
6)wipe cotten ball over hands and place it in the zip lock bag
7) repeat 4-6
8) Which Soap Works Best!!!!!!!!!!!!!!

the vinegar and baking soda volcano was always fun

Use the sun and a magnifying glass to burn wood.

I would suggest this little project, though I fear some namby-pamby administrator would view it as a deadly weapon and have your brother expelled. Well, no matter, there are plenty of other options, such as:

Fun with water pressure, though the glassware might be problematic

Penny in a balloon, which requires only a semi-clear balloon and a penny

Filter paper chromatography, which only requires coffee filters and black magic markers

I recall doing the filter paper thing, it is actually really impressive if you use multiple colors markers (say a red one first, and try a yellow on different piece of paper)

so far the penny and baloon one seems good, or the coffe filter one...though i dont have a baloon or coffee filter...

so keep em comin!
R and as for the volcano...we dont have the materials to make the base structure (volcano)

paper macshade (I have no chance of spelling a french word that I don't remember how to spell, I hope you get what I mean.) for the base of volcano should work.

prove that i exist, thats a challenge :D

paper mache, just how it sounds

paper mache = glue and paper...cuz thats all i got

making a kaleidoscope using three small mirrors.

use your resources to make 2 or more different bridges and subject the same stress tests, and get some physics math in your paper work to show forces from weights and such, definete A

4 Pieces of Cardboard
4 Pieces of Plastic/Saran Wrap
Pair of Scissors
Clear Tape
A Flashlight
A single camp stove
A Pot small two handle kind not the long single handle.
Water

Cut the cardboard to the approximate size of 12" wide and 36" high.

Cut a semi-Large square in the cardboard pieces (viewing area) Left side of the card board. Cover these holes with the saran wrap and tape it to the cardboard.

Cut a 1/2" strip approximately 32" high out of all of the cardboard pieces. on the right side. Then tape the pieces of cardboard together making sure that they are all facing the same way Small Slit on the right viewing areas on the left.

Place the cardboard around the camp stove, fill the pot with water, and let boil. Wait until the water gets hot enough to make steam then shine the flashlight at an angle into the box, after the water boils for about 10 minutes you will be able to see a (tornado), if done correctly the tornado will be higher out of the box approximately 4-5 feet tall. Will put a pic up if you need one.

Go to a supermarket (you may have to visit an Asian one or order online) and pick up some unflavored agar. (I used lemon-flavored and the results were disastrous. Writing about it got me into college though.) Get ahold of some sterile petri dishes (dirt cheap). Prepare the agar by boiling some water and adding it, then pouring it into the dishes and waiting for it to cast. Get some bacteria from a good source (e.g. your or his mouth), then swab it onto a plate. If you get a growing culture, you'll have a control sample of bacteria. Once you've prepared the original culture plate, you can pick various household items and add them to separate petri dishes, followed by agar gel. Once the experimental dishes are set, take a toothpick and scrape some cultures from the control and put them into the experimental dishes. Cover, incubate at as close to 37C as you can get for a couple days. Compare growth. (Good ideas for additives are salt, lemon juice/vinegar, baking soda, detergent, etc) It sounds complicated, but the concept is actually very simple.

You can get dishes and culture media here.
