Subject: Science Concept: Solid, liquid, or gas Sunshine State Standards/Access Points/Common Core: SC.2.P.8.2- Identify objects as solid, liquid, or gas. Primary Instructional Objectives: - Students will be able to identify what the difference is between a solid, liquid, and gas. - Students will be able to identify examples of solids, liquids, and gasses. - Students will be able to sort objects by whether they are solid, liquid, or gas. - Students will be able to define matter and where you…

The 'Wingate Cycle Ergometer Test' is an anaerobic test that is performed on a cycle ergometer. Eg. Monark. (Vandewalle et al. 1987). The aim of our test is to measure Peak Power Output(PPO), Relative Peak Power Output(RPP), Fatigue Index(FI) and Anaerobic Capacity(AC) throughout the Wingate Anaerobic Test. For both our participants we will compare our findings and provide an explanation for the similarities/differences we encounter between the two. Peak Power Output is the highest power output…

Result and discussion: Substrate specificity The substrate specificity for the PPO is represented in table. The Km values for catechol, L-DOPA, L-tyrosine, and p-Cresol are 4.12 × 10-3, 16.4 × 10-3, 6.12 × 10-3, and 5.01 × 10-3, respectively. Catechol was the best suited substrate, having the lowest Km value and highest Vmax value when compared to other 3 substrates (Table 1). Table 1: Substrate specificity of PPO enzyme Substrates Specific activity (units mg-1 protein) Km (µM) Vmax (abs min-1)…

INVESTIGATE AN ASPECT OF REDOX SYSTEM/REACTION Research Question: Does a higher voltage lead to more mass on graphite? INTRODUCTION Hypothesis: Higher voltage leads to more mass amassed on graphite electrode. Electrolysis- the process in which electric current passes through a solution to effect a chemical change. In this case there is copper, copper sulphate and graphite. In a electrolysis there is an electrolyte which is the copper sulphate, the anode which is the graphite. This is the…

OBJECTIVE For the first week of the lab, the objectives were to isolate and test for the presence of major components of milk, including proteins, carbohydrates, fats, vitamins, and minerals and to determine the presence of the various components of milk in the various fractions using qualitative tests for these substances. For the second week of the lab, the there were three objectives that related to the procedure: to determine the calcium concentration of milk using the technique of…

Research Question: How do different concentrations of nitric acid (measured in molars) with copper powder (grams) affect the rate of reaction (measured in seconds) measured using a stopwatch? Hypothesis: The copper powder placed in the most concentrated amount of nitric acid, measured in molar, will take the least amount of time, measured in seconds, to react compared to the amounts of copper powder in other less concentrated amounts of nitric acid. This is as if the concentration of nitric acid…

quinolines via Friedlander condensation in high to excellent yields at 70 °C under solvent-free conditions. Initially the reaction between 2-aminobenzophenone (1.0 mmol) and dimedone (1.0 mmol), as the model reaction was examined in the presence varying amount of tartaric acid as catalyst and the results are presented in Table 1. The best result was achieved by carrying out the reaction with 15 mol% of catalyst (Table 1, entry 4). Use of a higher amount of catalyst did not improve the yield…

The synthesis of Aa-g-poly(MAA) involve the optimization of various reaction conditions like initiator concentration, monomer concentration, crosslinker concentration, solvent concentration and pH. After the optimization of various reaction parameters the replications were carried-out in triplicates for the reproducibility of the results and statistical of the results obtained. It was performed using the Statistical Package for Social Science (SPSS) version 10. Statistical results of the…

composite has been investigated. For that purpose, the PMMA samples with Al2O3 additive prepared with different percentages(0,15,25,35 and 45) wt.% and different thickness. The experimental results showed that the D.C electrical conductivity increased with increasing the alumina concentrations and temperature. Also the activation energy change with increasing of additional alumina. The dielectric constant, dielectric loss, A.C electrical conductivity are changed with change the concentration of…

conversion of gas oil and yields of the products is expected(Akpa et al. 2010). When the flow rate of gas oil is increased, there is an increase in the heat inflow into the reactor, rate of cracking reactions are high, feed also spends less time in the reactor and hence less endothermic cracking reactions take place. This resulted in a slight increase of the conversion of gas oil from 73% - 74% (Fig 4.5). It was observed that as the flow rate of gas oil to the riser increases from 34Kg/s to…
