i need to know how to make a light form out of a batery and batteries for my sons science project?

No, you don't. Your son needs to know it. Maybe he can teach you after he's finished his project.

Ok, this is how you do it.  You need to have the following items: A coil of copper wire, a barrel shaped magnet, a tube, and a bulb.  Take the tube, and this could even be a paper towel cardboard center, and wrap coils of wire around the outside of the tube as many times as you can.  This should cover the outside of the tube.  Now, take the two ends of the wire and connect them to the + and - of the bulb that you will be using.  You must then place the magnet (a barrel magnet is best, but any will do.  The stronger the better) inside the tube, and cover both ends of the tube.  Now, as long as you are shaking the tube lengthwise, and the magnet slides up and down inside the tube, the bulb will shine.  To make a more practical flashlight, you could do one of two things.  Either have an electrical storage device that will hold the charge so you don't have to keep shaking it, or you could rig something up that will keep the magnet moving inside.  Either or both will work.

My kids use this website to get their science fair ideas http://school.discovery.com/sciencefaircentral/ It has project ideas, tip sheets, step-by-step instructions on basic science fair setup, etc.\n\nGood luck!

Here's a site with alot of different ideas and difficulty levels with instructions.  Maybe you can find something here.\n\nOr you can tell us more about what you are wanting to do and what you like and we might be more helpful on here.\n\nhttp://www.all-science-fair-projects.com/

Burn it in a sprectrophotometer.  Look at the emitted light.

It sounds like you are creating a basic electrical circuit. with the batteries, wires, bulbs and paper clip you can make either a series or parallel circuit. The light bulbs will light up when you have a complete single loop for series. When you measure the current it should be the same anywhere on the circuit. In a parallel circuit you are splitting the circuits into three or more branches, with one bulb on each side. When measured each branch should be using half the current. You shouldn't have any problem finding a site online that shows this experiment. use keywords, including science experiments for kids. I found the experiment in Reader's Digest,"How Science Works"

I would probably use Light Emiting Diodes connected to a low voltage dc source using very small gauge twin-lead wire.

Did this way back in Boy Scouts....Relatively easy...just need to build 2 electromagnets and a series circuit..... I'll see if instructions are online.\nhttp://www.terrax.org/comm/morsecode/buzzer2.aspx\nhttp://chss3.montclair.edu/~pererat/perbuild.htm\nthe second one is similar to what I built

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel

Since you need simple and portable, how about starting with something that uses light and prisms to create the spectrum? \nFrom there, you could go to show how rainbows are created ( where the light must be, what the sequence of the rainbow spectrum is) or compare how light colors mix compared to how m=paint colors mix.  I don't know if that is appropriate for the 10 th grade.  But working with light and prisms is always fun.\nmagnetism is always fun, too.

http://www.docrafts.com/ \nits a very good site for all kinds of projects difficult and easy and they have explained things to be done step wise... also if you have a colour priter get the print outs for reference ... hope your kiddo enjoys it !!!

a school science project?\nhow about a demonstration of how light flows through fiber optic cable, how you can change the color with a color wheel, change the look with different diameter fiber cable and lengths. you could make a really cool display that looks like a galaxy or some celestial picture...only thing is it has to be viewed in complete darkness, so you may have to build it in a box- or just turn out the lights. you could relate how it has effected the telecommunications world, etc...\nonly thing is may be hard to find cable at a cheap price with out buying bulk- but if you are resourceful you may do it, or you could buy cheap pens, or a hobby store may carry it. then as a light source use an LED and make a color wheel with clear plastic sheeting and colored sharpie pens, and battery energy source.\n\nhttp://www.cablecominc.com/fiber.jpg\nhttp://www.network-cables-guide.co.uk/images/fibre-optic.jpg\nhttp://www.arcelect.com/fibercable.htm\nhttp://electronics.howstuffworks.com/fiber-optic.htm\nhttp://www.delmartrading.com/images/products/FiberOpticPen.jpg\n\ngood luck, have fun

oh this has been awhile....ok a block of wood, a couple nails, some tape, some wire, and a six? volt battery.\n\nyou are basicaly making one of the nails an electro magnet so that when the circuit is completed it comes on and pulls down one of the wires to the top of it making a clicking noise, open the circuit the wire will spring back up.  \n\nhere is a more complicated one that will send to another one\nhttp://www.apluschilddev.com/headstart/services/projects/easy_make_telegraph.htm

here's what you need:\n\n1.18-gauge copper wire (smaller gauge will work too,2. but 18-gauge is stiffer)\n3.Wire clippers\n4.Steel paper clip (Some people find that a 2-inch 5.strip of zinc works better) \n6.Sheet of coarse sandpaper\n7.Lemon\n8.Help from an older friend or an adult\n\n\nhere's what you need to do:\n\n\nHave your older friend or an adult strip 2 inches of insulation off the copper wire. Clip the 2 inches of bare wire with the clippers.\n\nStraighten out the paper clip and cut about 2 inches of the straightened steel wire, or use a 2-inch piece or strip of zinc.\n\nUse sandpaper to smooth any rough spots on the ends of the wire and paper clip or piece of zinc.\n\nSqueeze the lemon gently with your hands. But don't rupture the lemon's skin. Rolling it on a table with a little pressure works great. \n \nPush the pieces of the paper clip and the wire into the lemon so they are as close together as you can get them without touching.\n\nMoisten your tongue with saliva. Touch the tip of your wet tongue to the free ends of the two wires.\n\nYou should be able to feel a slight tingle on the tip of your tongue and taste something metallic.\n\n\n\nwhat you will discover\n\nThe lemon battery is called a voltaic battery, which changes chemical energy into electrical energy.\n\nThe battery is made up of two different metals (the steel paper clip and the copper wire). These are called electrodes, which are the parts of a battery where electric current enters or leaves the battery. The electrodes are placed in a liquid containing an electrolyte, which is a solution that can conduct electricity.\n\nIn a solution of water and an electrolyte, like the acid in the lemon, an excess of electrons collects on one end of the electrodes. At the same time, electrons are lost from the other electrode.\n\nTouching the electrodes to your tongue closes the circuit and allows an small electric current to flow. A single lemon produces about 7/10 of a volt of electricity. If you connected two lemons together, you can power an inexpensive digital watch (uses about 1.5 volts). (Use a length of thin, flexible wire to connect the silver wire of one lemon to the copper wire of the other lemon. Then attach thin wires from the other two wires in the lemons to where a battery's positive and negative poles connect to power the watch.)\n\nThe tingle felt in your tongue and the metallic taste is due to the movement of electrons through the saliva on your tongue.\n\n\n--well, i just searched for it. hope i helped in a way ^_^\n\n-paul
