Science Fair
By:Arjun
We all know that the world is now facing an energy crisis and everyone is trying to do something about that. Now electrical energy or electricity can be made from air and saltwater. After all, both the air and the saltwater are freely available everywhere. Procedure: Set up a regular circuit with an electromagnet (iron core wrapped in a coil by a wire), switch, and battery. Replace the battery with a bowl of saltwater and keep the ends of the wires which used to be on the battery hanging above the salt water. See how many washers the electromagnet can pick. Once again replace the saltwater with the battery. See how many washers it can pick. COMPARE.
The concept is really confusing though later you get the hang of it. The same way that you burn wood and make heat energy, you should be able to burn metals and get electricity (or electrical energy). The difference is that you are not really burning instead, you are producing a condition for oxidization which by itself is the same as slow burning. If with one cup of salt water and some metals If I could light up a small light bulb, maybe you can light up a entire building by a tank of salt water and a few hundred pounds of scrap metal. What did you write for your science topic? Why did you choose it?

I did which causes chemical reactions with vinegar. I chose it because I like to see bubbling and test new things rather than old materials that I already know.
For my science fair topic, I chose Environments. My question was: Does the temperature of the water effect the plants growth? I am testing on plant with hot water, another with cold water, and the last one with regular room temp. water. I think it won't really make a difference but I'll find out. The reason I chose this topic was because I like working with plants and after this experiment, It will help me for later on when I am doing something with plants.
Great Post Arjun!
My science fair topic was can magnet conduct electricity. I did it because magnets seem like conductors(not the music conductor). It seem like a good idea because today I got the approval stamp. =p
I chose the topic for my Science Fair is... Are there better ways to kill ants rather than use ant spray. I'll test salt water and soap water and boiling water and icy cold water. The bad thing is that I'll need about 30 ants to sacrific their lives to do my experiment.
Really Good Post Arjun

My science project is on how to make lightning. I chose this because I was really fascinated on how real lightning works. It is really cool how you can make lightning at home with just an iron pot, rubber gloves, an iron fork, and a piece of a plastic sheet. It's actually not that hard. All you need to do is collect all the items I wrote in the sentence before this one. tape the plastic sheet to a table top. Put on some rubber gloves. Darken the room as much as possible. Rub the pan vigorously to and fro on the plastic sheet. Hold the fork firmly in the other hand Bring the fork slowly to the rim of the pan. When the gap between the fork and the pan is small. You will see a small spark jump across. That is the lightning.
Hi Arjun,
I did my project about rocks and minerals. I was going to find different rocks and minerals, but now I am only sticking with the basic kinds of rocks for example, Igneous, Metamorphic, and Sedimentary. Did you know that these kinds of rocks can all form into each other? For example, the Sedimentary rock forms into a Metamorphic rock when there is heat ( sun) and pressure (air). Then, when the Metamorphic rock melts (heat) it can from into Igneous rocks. Finally, when there is weathering, the Igneous rocks form into Sedimentary rocks.
I could tell you more about my project but, you can come see it at the Science fair!
Nice Project Arjun! :P
I wrote polluted river water but it didn't have enough info and didn't get a approve or disaprove.I choose it because I have always been intrested of what is making water polluted and want to find out. But i'm not sure how to test polluted water please help if you know.
GREAT POST!!!
Nice blog Arjun, my science fair is on can a citrus fruit make enough electricity to power a cicuit?
The reason I choose this topic is since the world is facing a energy crisis and some creating ways to generate electricity that would be big help are for example today in Japan there was a power failure because of another earthquake and a simple way of generating electricity would be to use some kinds of citrus fruits because the fruits do make electricity. Just guess if we had so many citrus fruit we could power the city.
These are the supplies
In order to geneate electricity through fruits we need
1. Citrus fruit (e.g., lemon, lime, orange, grapefruit)
2. Copper nail, screw
3. Zinc nail or screw
4.Light Bulbs
5.wires
You can make the circuit in a diffrent way Nice Post!
My science topic is: Do fruits have voltage?
I chose it because if the answer is yes, then you could replace a battery with a fruit instead. I also chose it because it is cool.
NICE POST, ARJUN!
For me, I did: What happens to dirty pennies when you put them in a mixture of lemon juice and salt? What happens after it soaks in that solution?
I did a test experiment (just to see if it works), and it ends up that the pennies get clean if they are in the solution! It looked so cool! I took a dirty penny, and put it in the solution halfway for about 10 seconds. When I pulled the penny out, one half was clean and the other half was dirty! When the pennies stayed in the solution for a while, they turned green, then disintegrate! (not literally) :) But it was close! Most of the penny was gone. You could even rub off the copper! You can literally see the inside of the penny! It was amazing! I chose this experiment, because I read it in a book. It looked super interesting, and also, I have always wanted to clean pennies. We have a LOT of SUPER dirty pennies that I wish we could clean. Now we can!
I have heard that there is a way fo tranferring electricity radioactivey from spac on huge solar plants orbiting the Earth.
Anyways my Science Project is going to be about if the rempeture of an magnet can affect the magnets magnetic field lines. So far all I have done was write my rough draft on the hypothisis and the Question.
I think that my project is the BEST!
Nice blog!!!
NICE AND OUTSTANDING POST ARJUN!!!!!
Most of the energy comes from fossil fuels that make our air unhealthy. Nuclear reactors are another source but they are very dangerous.
I chose the topic, electricity, for my science fair project, because I wanted to see if vegetables or fruits could produce electricity instead of using unhealthy and dangerous things.
Procedure: Build a circuit with a battery, light bulb, switch, a vegetable or fruit, and wires, in series. Keep on changing the vegetables and fruits to test if they produce electricity. Tip: I will try to take out the battery and see if the vegetable or fruit generates its own electricity.

I wrote about do plants grow better in salt water or sugar water?
Great Post Arjun!
AWESOME POST ARJUN! Mine was which household items make the best conductor? Well the bad part is that it didn't get approved. Anyway, my project is about electricity and magnetism. There is this "electrical bug" which has a lightbulb for a nose and it only lights up when it's foil hands touch a conductor. Nice science project.
NICE POST ARJUN!!!!!!!!
