Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate

MAKES VINCA PLANTS GROW THE BEST? My Science Experiment! The experiment is to take 4 Vinca plants‚ which are about the same size‚ health‚ and flowering stages and find out which one will grow the best. Each of the plants will have 75 ml of a liquid daily for 10 days. My Grandma bought them from Lowes on September 20‚ 2011 for me. Breakdown of the plants are as follows: Control plant will get tap water. Plant A will get Milk from the refrigerator. Plant B will get

Introduction Man has propagated plant material almost as long as he has cultivated the land to produce food. For a long time‚ plant material was propagated mainly by using the seeds of existing plants. Better methods were discovered over time‚ methods that allowed the farmer to retain the desirable qualities of the plant material‚ while eliminating some of the less desirable qualities. Through these methods‚ the farmer was also able to eliminate the variations between plants of the same cultivar and produce

are more to aquatic plants than just floating on the surface of water. Aquatic plants are plants that can adapt and live in a freshwater environment. They are sometimes called hydrophytes. These include plants that live in fresh wetlands‚ swamps‚ ponds‚ lakes‚ and marshes. This type of plant actually serves two important functions. First‚ they help oxygenate water (2006) and they provide nutrients and food for some fishes (Tappin‚ 2003). There are many types of aquatic plants including rooted‚ emergent
