Kids science: Electricity 102 Science >> Physics for Kids Important things to know about electricity? Conductors and insulators - Conductors are materials that allow electricity to flow easily. Most types of metal are good conductors, which is why we use metal for electrical wire. Copper is a good conductor and isn't too expensive, so it's used a lot for the wiring in homes today. A battery can act as a source of electricity in circuits. Batteries use chemicals that react to make electricity. Alternate and Direct Current There are two main types of current used in electrical systems today: alternate current (AC) and direct current (DC). Static Electricity Sometimes electric charges can build up on the surface of objects. Take a quick 10 question quiz on electricity. Electricity Experiments:Electronic Circuit - Create an electronic circuit.Static Electricity - What is static electricity and how does it work? More Electricity Subjects Science >> Physics for Kids

Science Fair Projects Paper battery holder tutorial | The Fine Art of Electronics {under construction} This tutorial shows you how to make a paper battery holder for coin cell batteries (CR2032 and CR2016). Scroll to the bottom of this page for the video tutorial. Materials and Tools battery holder template printed on cardstock (download PDF here) conductive copper tape (available at digikey and sparkfun)regular tape (e.g. scotch tape or masking tape)scissorssurface mount LEDs (White, Green, Blue, Red, Yellow)3V coin cell battery (CR2032 or the thinner CR2016) Steps Step 1: cut out the template Step 2: cut two pieces of copper tape, about 3 inches long each Step 3: make the positive lead Take one of the copper tape pieces and peel off the paper backing. Stick the copper tape over the horizontal part of the “L” shaped line, on the front of the battery holder, and fold the tape to follow the “L” shape. Leave the excess copper tape hanging off the battery holder. Folding to make the copper tape turn: At the turn, fold the tape back over itself so that the sticky side is up. This completes the turn.

Hundreds of Science Fair Projects For Students Thunderbolt Kids If we want to keep a record of how we constructed a specific electric circuit, we can take a photo of it. If we do not have a camera, we can remember the circuit by drawing a sketch. Look at the sketch below which Farrah drew of the circuit that you made in the activity with the paperclip switch. That's right Jojo. And as Jojo pointed out, all of us do not draw equally well! The table shows the sketch Farrah drew and the symbol for each of the components of our circuit. REMEMBER: a battery is made up of chemical cells. When we put these symbols together to represent an electric circuit, we call it a circuit diagram. Draw a circuit diagram of the sketch above. Compare your diagram with the one below. Take note that for electric circuit diagrams we represent the wires with straight lines. This is a simple and quick way to represent an electric circuit and it should be clear to everyone that this circuit has a battery, a bulb and a switch, all connected with electric wires.

That Thing There: Paper Circuit Projects from Maker Faire Detroit 2013 These are the "card" projects that I had at Maker Faire Detroit. I'm dividing the projects in two or three posts because I want to show the circuit paths both with and without notes and I didn't want the length of the post to get too unwieldy. Two quick notes: I took these pictures after Maker Faire and after they were abused examined many times over so they may look a little tired but that's because they are. However, this speaks to the hardiness of these structures. Also, all of these use Jie Qi's ingenious paper battery holder. The link takes you to a page where she generously provides a PDF of the holder to cut out and use as well as a link to a tutorial. The one shown above is the first card I experimented with. This is the circuit with my (hopefully) helpful notes of what's going on. Ralph Robot There's a note on this one to look here for the reason for the longer piece of copper tape on the "switch". Santa's Treats basic paper circuit off open circuit OK, that's it for the "cards".

Bristlebot: A tiny directional vibrobot The BristleBot is a simple and tiny robot with an agenda. The ingredients? One toothbrush, a battery, and a pager motor. The BristleBot is our take on the popular vibrobot, a simple category of robot that is controlled by a single vibrating (eccentric) motor. The starting point is of course the toothbrush. Cut off the handle of the toothbrush, leaving only a neat little robotics platform. Next, we need a vibrating pager motor or other tiny motor with an unbalanced output shaft. The kind that I got are happy to run on almost any common voltage– probably a range of 1-9 V. The last substantial ingredient is some foam tape. Attach the motor to the foam tape. A better method is to bend one of the leads down flush with the foam tape, so that you can *stick* the battery to the foam tape as well and still make an electrical connection. The completed BristleBot, running and ready for action.

bristlebots The Evil Mad Science Auxiliary is a public group on Flickr for anyone to add photos that are (at least marginally) related to posts and projects from Evil Mad Scientist Laboratories. Lately some fantastic photos and projects have shown up in the group, so we thought that we should stop and round up a few– not all– of the great things that we’ve seen there. The photos below were taken by their respective owners; click on the individual photos to get the full story. A dark detector built by cyenobite, using a tiny battery holder. Beautiful Joule Thief light by Jimmie Rodgers Adam Greig has been having fun with AlphaPOV. Francesco (Flickr user fdecomite) made this amazing army of BristleBots, photographed with the help of his spiffy LED ring light. Steve Lodefink has been busy building up this set of electronics for an extra-spiffy handlheld blaster. Channon (Flickr user plik the geek) is building up one of our interactive LED kits.
