LAB REPORT HYPOTHESIS 1: Plants transpire the most when the environment has light and less humidity JUSTIFICATION: Water evaporates more readily because light stimulates the opening of the stomata and photosynthesis would occur. HYPOTHESIS 2: Transpiration would occur the second most when there’s light and lots of humidity. JUSTIFICATION: The light would allow photosynthesis to occur and the stomata to open but little if any diffusion of water out the leaf would occur. HYPOTHESIS 3:

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

Calorimetry Lab Report Waris Butt PHY 112 Mr. Fasciano Class #18336 06/08/14 Purpose: Heat flow will occur between objects in contact until no more heat flow is detectable. Using calorimetry to analyze heat flow quantitatively and the equation: Q = mc ΔT‚ to determine the specific heat capacity of an object and heat flow from or to an object; respectively. Materials: Circle K 44 oz Styrofoam cup with lid Large Plastic

Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due to a force‚ of an object have different accelerations (∆v/∆t). The more massive the object is‚ the smaller its acceleration. Newton’s third law of force says that if two object interact‚ the force F12 exerted by object 1 on object 2 is equal and opposite to the force F21 exerted by object 2 on object 1. The action force‚ F12‚ and the reaction force‚ F21‚ act on different objects. Illustration

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We

Corte Madera Scientific Report Abstract I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my

Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol
