Kevin Doherty Experimenting with Plant Growth Team Rocket Science Introduction: The purpose of the experiment was to establish whether the concentration of Schultz fertilizer that was added to the radish seeds effects the speed of growth during the six-week time frame of the study. The major variables with this study are proficient communications among the team‚ the seeds‚ soil‚ water concentration‚ fertilizer‚ light exposure‚ temperature of the room‚ consistency of following watering (watering

Acid Rain and its Chemistry Acid rain is a type of pollution that is becoming a major threat to our planet and is need of attention. Acid rain has significantly increased ever since the industrial revolution‚ and now around the world‚ countries like Russia‚ China‚ and those in Europe are facing increasing levels of acidity in their rain. Not only is it becoming more acidic but it is also spreading by the pumping of sulfuric gasses deeper into the atmosphere from of the use of taller smokestacks

has a tremendous variety of oxidation states that appear in its compounds. The oxidation numbers range from Mn (III) in compounds like Mn(NO)3CO to Mn (VII) in KMnO4. Compounds of manganese range in oxidation number between theses two extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful starting material for the preparation of other Mn (III) compounds. Manganese (III) complexes are relatively stable and can be prepared

Acid Rain Definition: The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852‚ when the English chemist Robert Agnus invented the term. From then until now‚ acid rain has been an issue of intense debate among scientists and policy makers. Acid rain‚ one of the most important environmental problems of all‚ cannot be seen. The invisible gases that cause acid

Bread Mold Experiment Mold is something that we often take for granted‚ as something that makes us have to throw the bread away or the cheese smell bad. Mold is‚ in fact‚ a fascinating organism which has had many different uses over the years and our lives would not be the same without it. Most of us know that food seems to become moldy more quickly in the summer than in the winter when it is colder. Food in refrigerators seems to keep longer than food left out in the sun. Is this true? Does temperature

Individual Project Unit 2 Experiments In this individual project we were asked to conduct three experiments. The three experiments I chose to conduct were Experiment 1‚ Experiment 2‚ and Experiment 4. I have documented my findings for the experiments that were done. In Experiment 1‚ I was to rub my index finger gently over a piece of very coarse sandpaper for a few times. Then‚ I was to rate its coarseness on a scale from 1 (very soft) to 7 (very coarse)
