A. Avril Crayfish Lab Report November 9‚ 2012 Dr. Marvin Results: Figure 1. Firing Rate of Tonic Receptor in Response to Stretch. The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

all calculations‚ below is what we concluded. The molarity you had to be careful with because it was moles/liters and our readings were in milliliters so we had to convert first. In conclusion‚ even though the lab procedure is not about moles‚ most of the calculations are and this is one lab where the concept of

(Jackson and Baker‚ 1986). The purpose of this study was to determine the contributors to the sit-and-reach flexibility test. METHODS The subjects in this study were 11 female and 10 male college aged students that appeared to be healthy and active. Four methods were used to obtain the flexibility measurement of the test subjects. A goniometer was used to find the flexibility measurements of the subjects for the shoulder flexion‚ shoulder extension‚ hip flexion‚ and hip extension tests. Using the

We labeled the test tubes with numbers one through five. The first test tube was our calibration tube‚ here we added one milliliter (mL) of buffer‚ four mL of distilled water and three drops of chloroplasts using pipets. After‚ we created the solution for the second‚ third‚ fourth and fifth test tubes by adding one mL of buffer‚ three mL of distilled water one mL of DPIP an 3 drops of chloroplasts

the percent yield by dividing the expected yield‚ the amount of product that should be produced based on your stoichiometric calculations‚ by the actual yield‚ the amount of product that is experimentally obtained from a chemical reaction. In this lab‚ I have determined the reaction for mixing two reactants together; I measured out 0.005 moles of each reactant‚ lead (II) nitrate and potassium chromate. I dissolved‚ mixed‚ and made them react to make products; I compared the mass of the two reactants

Introduction In this lab‚ the purpose was to verify Hess’s Law. Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The enthalpy of reaction‚ ΔHrxn is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference in enthalpy of the products and the reactants and is independent of the steps

zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a. Research question ¿Does the quantity
