Work Investigation Purpose: In this lab‚ you will work with a partner to investigate the force required to do work on an aluminum plate as you pull it at different angles. Materials: 1 aluminum plate String 1 kg mass (you might need to use two 500-gram masses) 1 spring scale Prediction: Before you begin‚ sketch a graph that shows your prediction of the relationship between the force and the angle you pull it at. In other words‚ what patter do you think the graph will demonstrate? Procedure:

ADI Lab investigation: Photosynthesis Introduction and goals: In our experiment we worked with photosynthesis‚ which is the process of light energy‚ CO2 and H2O being turned into food for the plant. CO2+H2O+ Light energy=C6H12O+O2 is the formula for photosynthesis. Our group hypothesis was trying to determine weather o2‚ water‚ or the nutrients of the soil determine the mass of the water. The guided question was “Where does the mass that makes up a plant come from?” Methods:

Beanium Investigation The purpose of this investigation was to find the average atomic mass for the element Beanium with three isotopes. The average atomic mass is the average mass of the atoms of the element divided by the total number of atoms. An isotope is an atom with the same number of protons‚ but different number of neutrons; they are different forms of a single element. Since we knew the isotopes had almost the same amount of sub-atomic particles‚ we made our hypothesis the following:

available belt widths were 16‚ 25 and 32 mm. The belt has a loading capacity of 60N/mm‚ which is combined with torsion in the equation to find the belt width: The shaft hole (and so size of shaft) is determined by the shear strength of the fit of the pulley onto the shaft which is 186 MPa. There are three shaft diameters (10‚ 15 and 20) and the correct one is found by the equation Weight Saving Design Rationale Creating four straight material saving holes seemed like a simple and relatively

During an undercover investigation‚ Officer Cline witnessed Defendant #1 purchase a bag of what appeared to be marijuana and LSD. When Officer Cline approached the dealer (Defendant #2)‚ he was given a similar bag. Following the purchase‚ officers approached and arrested both defendants on narcotics violations. Forensic tests later revealed that the contents of the bag were nothing more than honey and dried leaf matter and rolling paper coated with lime extract. The defense attorneys for both defendants

Conductor Investigation Experiment LabReport Introduction This experiment is about to test how will the nichrome wire effect the ampere of the electric current. All the possible factor that will effect to the volt of the current • The Length of the wire • The Diameter of the wire • Temperature • Magnetism Aim To determine the effect of the length of the wire on the ampere of the electric current. Hypothesis Nichrome is an alloy(a metal made by combining two or more metallic elements)

Background Information Part 1 In the first part of the enzyme lab‚ we mixed a substrate and an indicator with an enzyme. There was also a neutral buffer in each of the chemical mixtures. The neutral buffer regulated the pH to around 7. We got a color palette and once we mixed each together‚ we observed and saw a change in the color of the substance. The darker and more brown the substance got‚ the more oxygen produced by the reaction. Our results showed that amount of oxygen produced increased

John Abarshi Mr Meinsma Chemistry December 14‚ 2010 Conductivity of Ionic solutions Introduction This lab report is about the conductivity of ionic solutions. In class we have been discussing wether all ionic solutions conduct equally well. If an solvent solution conducts electricity‚ then it must contain ions. So measuring the conductance of solutions can tell you whether the solutes in the solution are dissociated into ions. (Conductivity) Any type of solution‚ even ionic solutions‚ provide

INVESTIGATION INTO THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a
