...Final Investigatory Project for Group 5 I. Problems and Setting A. Introduction Batteries, years ago, have taken the world by a storm and have since than became a necessity in one’s household. Sadly, even though they are tremendously useful, batteries have drawbacks, such as semi- affordable costs, limited shelf life and pollution. Our group had an idea on how to make an alternative to this that would not only work like the real thing but would also be healthy to our environment and light in our pockets. This idea turned out to be realty and became the main goal of our Investigatory Project. B. Problems Finding an item that is easy to obtain and at the same time affordable, simple and earth- friendly is not an easy task. After a lot of thought, our group decided to use one of the objects that is almost always present in our daily lives: fruits and vegetables. Will these everyday materials such as apples, bananas, oranges, lemons and potatoes conduct electricity? Well, let’s see about that. C. Hypothesis A circuit is made up of a path, a source and a load. We believe that we should connect them with a (+) and a (-) wire so that the flow will be even with no reverse polarity. The load we thought of using was a battery- operated clock, one of the most common materials found in almost everyone’s household. We believe that it would work because the organic materials we will use have electrolytes that flow freely on its own. Thus, it will flow into conductors to make...

...Potato Powered Clock Theory: Potato as a Battery Hypothesis: Potatoes have starch in them which is a natural sugar that can be broken down naturally for a release of energy and generate enough power to run a digital clock. Problem Statement: Can ordinary potatoes power a digital clock for more than 24 hours? Variables: * Independent Variable – Potato * Dependent Variables – Clock, connection wires, copper and zinc plates Materials Needed: * Digital Clock with 2 Wires * 6.25” Connecting Wire * Transparent Tape * 2 4” Copper Strips * 2 4” Zinc Strips * 2 Potatoes (Oranges worked too) Background: How it works * A potato can be used as a battery by using strips of zinc and copper in the acidic juice of the potato to provide power to a digital clock. * With the zinc strip, the natural acid in the potato dissolves the zinc freeing electrons. * The copper wire uses the electrons that the zinc wire frees. * To obtain enough electrical current to power the clock, two potatoes must be used and they must be connected in a head-to-tail series. Steps: 1. Put potatoes into containers to stabilize them. 2. Insert Zinc strip from the clock into the left potato. 3. Insert Copper end of the loose strip into the same potato, 2 cm apart and parallel to the Zinc strip. 4. Insert Zinc end of the loose strip into the right potato. 5.

...that offer similar products to consumers. Energizer has been around since 1986 and has grown into a mutli- billion dollar company within the last decade. Duracell first got started in the 1920’s from two scientists, and finally become a brand in 1964. This paper will discuss the two companies’ background, the competition between the two, and how they will thrive to compete in the market place in future. Energizer Energizer is formerly known as Eveready Battery Company and changes its name in the late 1980’s. By the 1990, Energizer has established their brand and had over 30 percent of the domestic market. They were trailing Duracell by 10 percent, who at that time had 40 percent of the domestic market. Energizer is the manufacturer of dry cell batteries and flashlights, with a full line production of in three major categories: alkaline, carbon zinc, miniature and rechargeable batteries.

...weapon. I will explain what argument I will use and why I chose that argument. I will also explain why I didn’t chose the other argument. I will give you definitions of aggravated assault, aggravated battery, simple assault and simple battery. I would not chose argument number 2 Sharon should not be charged with aggravated assault and battery, but only simple assault and battery, since no deadly weapon was used. The reason I would chose this argument is because I would say the wine bottle was not a deadly weapon. I would research and see if there were cases that were similar to this case. I would prove that the wine bottle was not broken at the time of the event and that is why it was not a deadly weapon. Here is a case of a women hitting her husband with a wine bottle. Susan Van Cook, 42, of Trails End was charged with two misdemeanors (Leslie Korngold). I would not chose argument number 1 because it would be hard to prove by reasonable doubt that she did this because she was drunk. I am thinking that if you use argument number 1 you could also say she was afraid he was going to hit her first. I think that this argument would be too hard to prove. I could be wrong and this may be easier to prove then I think. Here are the definitions of aggravated assault and aggravated battery. aggravated assault n. the crime of physically attacking another person which results in serious bodily harm and/or is made with a deadly or dangerous weapon such as a gun, knife, sword, ax or blunt...

...Build Your Own Micro RC Surveillance Robot HOW DO YOU BUILD YOUR OWN MICRO RC SURVEILLANCE ROBOT? Why don't I show you how? Almost every roboticist has wanted to create a small Surveillance Robot at some point in their time. The biggest problem being the Receiver/Transmitter pairs are always too expensive. My solution: Extract the RC receiver from a small RC car and modify it for our purposes. By the end of this tutorial, you will create and modify an RC robot to do: 1. Direct Radio Control using the remote's joysticks. 2. Computer control via a microcontroller connected to the remote. Later, I plan on making this base teleoperational. When I do, I'll be sure to document it and continue the tutorial for it!!!!!!!!!! It will used the receiver from a $10 ZipZaps RC car purchased at a RadioShack (US) or a Microz GT car purchased at The Source (Canada). Any inexpensive RC car, though, will do. It will also use a wireless camera and 2 Solarbotics gear motors. The main goal of this robot always remains the same; to be able to perform surveillance that you could watch on your television or on your computer (this depends on the camera used). I broke this tutorial into steps for simplicity and organization of categories (why should you put the construction of chassis with building the electronics? :P) Now for some general examples of the design for the robot (you don't have to follow my example exactly). The image at the top of the page shows an angled view of...

Chances are your child has already done some school projects using the family computer. He's had to research the Web, or type and print out a report. Now you may be considering the purchase of another device to support his needs as he heads into tween hood, high school and beyond. What is best - a laptop or a tablet? What device will be more advantageous for schoolwork, and also support the social networking and game playing that kids will inevitably want to do? Technology Use in Schools Here are some examples of how kids are using technology in schools. * Online and visual learning: Many teachers have incorporated videos of lessons into their plan, either of themselves teaching the lesson, or from an outside source. Often, watching an assigned video is part of the homework. * Practicing skills: Playing math games are a fun way for kids to practice skills or math facts. Students also practice test taking or other skills with online games. * Researching topics: At an early age, schoolchildren start using the Internet to find information about topics they are learning about.
