Economics The Corn Industry The majority of food that is consumed by Americans contains corn‚ high fructose corn syrup‚ corn-fed meat and corn-based processed food. Corn is found in three out of four supermarket products. There are more than 3‚500 different uses for corn products. Corn subsidies in the United States totaled $81.7 billion from 1995 to 2011. Corn draws in more subsidies than wheat‚ soybeans and rice combined. The average American spends $267 a year on corn products. Americans

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

that acid rain has or does not have on seed growth and germination. The observation gathered from this experiment was that regular rain water that has a neutral pH is a better solution for seed growth. The seeds that were watered with the well water prospered more than the ones grown in the lemon juice solution. The results from this experiment were a little confusing‚ because in the first trial the seeds watered with well water germinated more than the seeds watered with the acid rain solution. Unfortunately

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

potential to damage crops extensively‚ and thus‚ damage society as well through shortage of food or even famine. In addition‚ in countries that depend on the production of agricultural goods like Canada‚ the effects of acid rain can be tremendous. In this lab‚ we have chosen to examine the effects of acidic and basic environments on radish plants (Raphanus sativus)‚ by implementing varying pH levels of buffer solution into the soil. We have allotted a total of four days (Tuesday‚ April 10‚ 2012- Friday April
