Fava beans grow best in areas with long, cool summers and do not like very high summer temperatures. The best time to plant fava beans is during early spring. Plant seeds 1 to 2 inches deep and 3 to 6 inches apart. Harvest fava beans when the pods are still green, but thick and full of seeds. Lima beans are also referred to as butter beans.
This soil is referred to as vermicast, or worm manure that can be used as a fertilizer for planting. Vermicast has been shown to have a reduced number of contaminants and an increased number of nutrients. In a previous study, the effects of vermicast composting were applied to Amashito peppers versus regular soil. The experiment resulted in a significant difference in plant height, mass, and leaf count when the peppers were planted in vermicast. While this isn’t technically observing the benefits of added worms, it does show that worms alter the soil in a way that aids in plant growth.
Enzymes work using a simple ‘Lock and Key’ theory this is when to substances fit together perfectly because of their shape and size, the theory is demonstrated in the diagram below: Temperature is very important to productivity of the enzyme reactions. If the temperature is too high they move around too fast and there are less successful collisions; if the temperature is too low then they move around slowly and therefore collide less often which in turn creates less successful collisions. There are several factors which can affect how fast an enzyme reacts these are temperature, mass and surface area. Out of these three we have chosen to investigate the surface area. We will be using the enzyme from the liver and placing it in hydrogen peroxide, this will create oxygen and water, we will measure the amount of oxygen produced we will catch and measure it in a measuring cylinder.
Iron (II) Sulfate is also harmful if ingested, and could cause death. It can be used as a nutrient and agriculturally. Copper (II) Sulfate Pentahydrate is used in agriculture as a pesticide, germicide, feed additive and soil additive. (http://chemicals.etacude.com/c/copper_sulfate2.php) Mole- a chemical mass unit, defined to be 6.022 x 1023 molecules, atoms, or some other unit Molar Mass- the mass of one mole of a substance Balanced Equation- an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products Oxidation Reduction Reaction- a half-reaction in which a chemical species decreases its oxidation number, usually by gaining electrons. Single Replacement Reaction- a reaction is characterized by one element being replaced from a compound by another element.
I think this experiment will be a great eye opener for many people. Problem How does caffeine affect the growth of organisms? Hypothesis My hypothesis is that the caffeine will in fact stunt the growth of the mung bean plant. I believe this will happen because I have always been told not to drink too much caffeine because of the affect it has on the growth of organisms and the way it affects how hydrated and energetic people are. Brief Explanation This experiment will test the effect of caffeine on the growth of mung bean plants.
Bean Sprouts Experiment Lab Report Research Question (Aim): To determine whether the different amounts of water affect seed germination. Hypothesis: I hypothesize that the largest number of seed germination will occur in the petri dish given 10ml of water. I believe that because, if the plant receives too little water, it will cause the plants to wilt. The plants wilt as they lose water quicker than they gain it from the soil. If the plant collects too much water, it will cause the roots to rot, resulting in the plants not being able to receive enough oxygen from the soil.
relative mass using beans September 18, 2012 Variables The independent variable for this experiment was beans. The dependent variable, that depends on the independent to change, was the mass per bean. The control does not change and this experiment it was the amount of beans (60). Purpose The purpose of this lab experiment was to lean about the average mass and the relative mass using different types of beans for representations. The safety precautions for this lab was to wear goggles while in the laboratory and to wash hands after the lab.
The other problem from the heavy application is the concentration of salt in the soil and chemical imbalances. On the other hand, although organic fertilizers are made from the living matter, they can make an effect. Organic fertilizers are deplete the nitrogen because the complex bacteria action. Soil and plants are damaged by this problem. Furthermore, organic fertilizers have no exact elements while chemical fertilizers can be calculated when give them to
There are some exceptions like Pepsin, a Digestive Enzyme which has a Ph of 2, which is found in the stomach of humans. In contrast, Trypsin is a digestive enzyme that works in the small intestines where the environment is much less acidic. Its Ph optimum is Ph 8. Environmental conditions are important in enzymatic reactions because temputure, ph, and chemicals that influence enzymes can influence them. Enzymes are practically or completely denatured if the ph is changed from the optimum Ph.
The question asked for this experiment was at what concentration these harmful chemicals in hairspray would have an effect on plant growth, specifically Wisconsin fast plant radish seeds. It was previously found that concentration of a contaminant in a plant is determined by its equilibrium with its concentration in the soil interstitial water (Chiou, 2001). So, for this experiment, hairspray was mixed with water at a 5%, 10% and 15% concentration before the solutions were added to the plant containers. The growth of each seed was compared to the growth of the control plant that was indulged in only water. The hypothesis for this experiment was that the higher the concentration of hairspray added to the plant, the bigger the effect, and therefore the least amount of growth.
