experiment was composed to show the effects that different colors of light have on plant growth. We separated our plants into different boxes and then covered the openings with colored cellophane. We conducted this experiment for approximately two weeks. Out of the colors blue‚ green‚ red‚ and yellow‚ the plant behind the blue cellophane grew the most. Research Problem What effects does different color light have on plant growth? Hypothesis The plants will grow taller under the red and blue

Synthetic marijuana or synthetic cannabinoids also known by many other names such as spice and K2‚ refer to a growing number of man-made mind-altering chemicals that are either sprayed on dried‚ shredded plant material so they can be smoked (herbal incense) or sold as liquids to be vaporized and inhaled in e-cigarettes and other devices (liquid incense). The effects of synthetic cannabinoids are similar to those produced by marijuana: elevated mood‚ relaxation‚ altered perception‚ symptoms of psychosis

Synthetic fibers are made from synthesized polymers or small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a long‚ linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibers. Although there are several different synthetic fibers‚ they generally have the same common properties. Generally‚ they are known

Good portions of these are combinations of synthetic fibers woven or threaded together to make a final product. These synthetic fibers are a large group of polymers. Synthetic polymers offer more possibilities‚ since they can be designed with molecular structures that impart properties for desired end uses. All fibers are ploy-something or polymers. That means they are long strings of repeating chemical elements. Some fibers come from ground plants that synthesize connected units of cellulose

Abstract The purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected‚ we were able to conclude that when seeds are exposed to radiation‚ it affects how they grow‚ if there is any growth at all. Introduction Radiation is an important environmental abiotic factor for plants‚ and one small section of the electromagnetic radiation spectrum‚ is called the Photosynthetically Active Radiation (PAR)‚ provides

Summary Synthetic marijuana is a big trend in our community because there are no drug tests for this yet and you can buy the product at a head shop‚ and a tobacco store over the counter. This has been an ethical problem in our world today because a lot of people are dying from it‚ where I am at they had a person die from the synthetic marijuana a brand called "Black Widow." They had a protest in my town to ban the Black Widow because it caused someone to die from the chemicals that was in it. I

Volatile Organic Compounds (VOCs) have become the greatest challenges to the preservation of the environment today. This group of chemicals is used in almost every sphere of life from industries‚ government institutions and domestically by both an ignorant and knowledgeable public. This paper aims to put to light examples of such compounds‚ look at the effect on the general populace and the environment and outline possible remedies to negative impacts. At the same time‚ it is important to look at

JEANNE BRETT Negotiating for Fertilizer Moises Postigo‚ manager of external relations and research for One Acre Fund (OAF)‚ needed to buy fertilizer for farmers enrolled in OAF’s program in Bungoma‚ Kenya. The conditions under which he would do so were complex: OAF was just two years old. This would be its first large acquisition of fertilizer. Postigo had five potential suppliers‚ none of whom he had ever met face-to-face and would not during these negotiations. Over a period of several weeks‚
