With the worlds population growing constantly quicker and more reliable ways to produce foods need to be made. Through hydroponics more plants and crops can be created in a shorter amount of time. "Hydroponics is an excellent method of conducting research with controlled conditions of nutrient availability." The problem is that if the exact amount of minerals are not used the produce may have negative side effects or unwanted results. Through the research of hydroponics the less fortunate can

Objectives: To use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions:

Transpiration Abstract This lab demonstrates how different environments effect the rate of transpiration in plants. A potometer is set up and placed in four different environments: one simply at room temperature (the control)‚ one with a fan pointing toward it creating a gentle breeze‚ on with a floodlight on it and a beaker felled with water as a heat sink‚ and one where the leaves are misted then covered with a transparent plastic bag. It is imperative that the tubing doesn ’t have any bubbles
