Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

The Effect of Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

Lalin Candium Lab Report Chemistry Block H Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes Objective: In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment‚ it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due

I. Objective The first objective of the measurement of thermal conductivity & one-dimensional heat conduction experiment was to identify three different metal specimens by comparing their experimentally determined thermal conductivities to known thermal conductivity values of existing metals. The second objective of the experiment was to establish a connection between the thermal conductivities & temperatures of the metal specimens. Thirdly‚ the contact resistance of the interfaces between

Abstract By working with physical isopods‚ ordinarily known as pill bugs‚ sow bugs or roly- polies‚ we tried whether these sowbugs favored a dark spot to a light place. Included in the lab are a few outlines and tables sketching out our aftereffects of the test. We measured recurrence

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches

ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations by finding the percent mass of each solution once the experiment was completed

I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration
