When an ion gains or loses electrons without becoming neutral‚ its electronic charge is altered in the process. In chemistry the loss of electrons is called oxidation while electron gain is called reduction. The first battery was created in 1799 by Alessandro Volta . Today batteries provide the power for an amazing variety of devices‚ everything from flashlights to robots‚ computers‚ satellites and cars. Inventors and researchers

in population and the unremitting inflation of prices of basic commodities has always been there. In view of this‚ it is important to develop other food sources that are easily available and affordable without sacrificing its nutritive value. This study was conducted to establish the following – 1) the phytochemical - nutritive and antinutritive composition of cassava leaves through research; 2) the degree of acceptability of cassava leaves as a nutritious and natural extender to meat; and 3) the

Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after being

Potato Cell Cytoplasm Composition PURPOSE: To determine the concentration of salt in the cytoplasm of potato cells HYPOTHESIS: Increase in salt concentration results in a hypotonic solution where the mass of the potato increases due to the movement of water into the cell. On the other hand‚ decrease in salt concentration results in a hypertonic solution where the mass of the potato decreases due to the movement of water outside the cell. MATERIALS: Potato Forceps Stopwatch Scalpel Test

Lemon Battery creating a battery from a lemon is a common project in many science text books. Successfully creating one of these devices is not easy. Batteries consist of two different metals suspended in an acidic solution. Copper and Zinc work well as the metals and the citric acid content of a lemon will provide the acidic solution. Batteries like this will not be able to run a motor or energize most light bulbs. It is possible to produce a dim glow from an LED. The picture at the top

This science fair project is designed to show how dogs heart rates increase with exercise and activities. Loads of people were wondering if older dogs’‚ or younger dogs’ heart rates would go up more when exercised. Well‚ we can show you! The hypothesis is that hopefully the younger dogs heart rate won’t go up as much as the older dogs’ heart rate. This science fair project is relevant due to people needing to recognize how to exercise their dogs according to what they can and can’t do age wise

I am Jessica Bogde and the title of my project is‚ “The Catapult.” I chose to do this project because in the fourth grade‚ one of my peers inspired me to build a catapult because she built it as her Science Fair Project. I also wanted to do this project because I love building things and this project just added to my experience in building things. I chose to work alone on this project because I work faster when I am independent because other people mess around sometimes. I also chose to do this
