The effect of water and fertilizer on corn seedlings Biology 1108 Lab Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some

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 the plant same time every

Effect of varying Temperatures on Enzymatic Activity of Bacterial and Fungal Amylase and hydrolysis of Starch Abstract This experiment consisted of setting up a control group of starch in various temperature and then placing both fungal amylases and bacterial amylases in a mixture of starch and placing the solution of amylase and starch in various temperatures of water. After a certain amount of time- different amount of time needs to be used in order to have reliable results- iodine is added

Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application

The ‘Experiment’ by Dr Haskell portrays the unusual experiment that he conducted to compare his bare body and a Chickadees body in harsh freezing conditions. He decided to investigate it further because there was no logical explanation for a tiny bird to be able to survive in such conditions. He related his astonishment to the Bergmann’s rule‚ which states that larger animals will be found in colder climates and smaller animals will be found in warmer climates. Haskell found that the Chickadees

To investigate the effect of different caffeine concentration on the heartbeat rate of Daphnia at room temperature. Introduction: Caffeine is found‚ and produced in many plant species to function as a natural pesticide‚ and as an inhibitor of seed germination of other nearby coffee seedlings to give it a better chance of survival. Caffeine is able to paralyze and kill certain insects upon feeding on the plants that produce caffeine. Coffee‚ tea and cocoa are common caffeine-containing
