following potential problems or hazards when not properly disposed off. Batteries pollute the lakes and streams as the metals vaporize into the air when burned. They can contribute to heavy metals that potentially may leach from solid waste landfills. They expose the environment and water to lead and acid. They contain strong corrosive acids which cause burns or danger to eyes and skin. In landfills‚ heavy metals have the potential to leach slowly into soil‚ groundwater or surface water. Dry cell

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

The History of the Potato Chip One of the most recognizable snack foods is the potato chip. Who can resist this thin slice of potato‚ fried into a crisp then salted? Potato chips are delicious and very popular. They satisfy the taste buds of many by hitting all the essential characteristics of a good treat. They are convenient‚ easily found‚ salty‚ greasy‚ and come in a wide variety of flavors. It is hard to believe their invention was a mistake. When George Crum‚ a Native American chef in Saratoga

POTATO INTO BATTERY Abstract a.Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result It did go well and the potato did give voltage to the equipment (clock) However‚ 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

Science Research Paper: “Potato Battery” I. Problem a. Main Problem This study aims to prove whether fruits and vegetables are good reserves of electricity. The potato‚ known for its high Phosphoric Acid and Sulfuric Acid‚ has been as our chosen fruit to prove and conduct our answers upon the accessibility of fruits and vegetables as an effective renewable energy source. b. Sub-Problems To further provide extra and specific information‚ the researchers have decided to add the following

Group 2 Science Investigatory Project I Title: Potato Battery II Objective: We only need a potato‚ a couple nails and a piece of wire to make a potato battery. It’s a fun science project that helps show the way things work in a battery by using everyday items we see around the house. The goal is to learn more about electricity‚ and possibly a few new science terms along the way. III Materials: * Two Potatoes * Two short pieces of heavy copper wire * Two common galvanized nails

______ 1. Background: Potato is a starchy‚ tuberous crop from the perennial “Solanum tuberosum” of the Solanaceae family (also known as the nightshades). It originated from the area of present-day southern Peru and it’s now grown worldwide. Potatoes were first introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world ’s cuisine. It is the world ’s fourth-largest food crop‚ following rice‚ wheat‚ and maize. Wild potato species occur throughout
