The Power of Mindfulness
'My key to dealing with stress is simple: just stay cool and stay focused.' Ashton Eaton. How can a person develop mindfulness to improve his responses to stressful situations? In the first part of our series on mindfulness, we discovered that in order to develop mindfulness, you have to become more aware of your thoughts and emotions at all times, even if you’re working on something stressful. You also have to remind yourself to look inward at all times so…...
Gruesome Experiment in The Auschwitz Concentration Camp
Out of 3,000 children, only 200 came out alive. The other 2,800 died horrible deaths while being used in horrible experiments in the Auschwitz Concentration camp. These experiments were called the Twin Experiments and were conducted during the Holocaust in 1943-1945 until the camp’s liberation in 1945. By the end of the Holocaust, only a few of the children were able to survive the brutal twin experiments conducted by Josef Mengele at the Auschwitz Concentration Camps. Josef Mengele, also known…...
Daphnia Experiment Lab Report
The essay sample on Daphnia Experiment Lab Report dwells on its problems, providing shortened but comprehensive overview of basic facts and arguments related to it. To read the essay, scroll down.When the animal is warmer, the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. (Campbell, 2005) Alcohol is a depressant. This means that body systems will slow down when alcohol is introduced. In particular, the heart rate will get consistently lower.…...

Dialysis Tubing Experiment Lab Report
The following academic paper highlights the up-to-date issues and questions of Dialysis Tubing Experiment Lab Report. This sample provides just some ideas on how this topic can be analyzed and discussed. Diffusion and Osmosis Through Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what eve knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 miss and…...
The sample paper on Epsom Paper familiarizes the reader with the topic-related facts, theories, and approaches. Scroll down to read the entire paper.We can see clearly from these graphs that as the concentration increases so does the rate of reaction. From the relatively straight lines of best fit we can tell that the rate of reaction is continuous with each different concentration. Scientific Model: From these results we can tell that as the concentration of H2SO4; when increased in the…...
Molar Volume Of A Gas Experiment
Which in turn would give lower liters per mole ratio and State that there is less H2O gas then there actually is. Molar Volume Calculation for distorted trial one ;0. 011 L H2O = IS. Mm/L (4. 9 x 10-4 -e . 0002 mol of distortion) 7. A different student fails to insert the stopper into the flask while determining the available volume of the 125 ml flask. What effect does this error has on the calculated molar volume? Mathematically…...
Yeast Fermentation Experiment
In this lab, the purpose is to measure whether the changes of substrate concentration will affect the rate of anaerobic respiration. Because the rate of reaction refers to how quickly the reactants are used up or how quickly the products are formed, one method is to measure the volume of gas given off, the more gas given off per time interval results faster reactions. Question: Will the changes in substrate concentration affect the rate of anaerobic reaction? Why or why…...

Molar Absorptivity Of Red 40
Absorption Spectroscopy Author: Lab Partners: Instructor: Chem 152 Date Work Performed: Date Work Submitted: Abstract A Beer’s Law analysis was used to determine the molar absorptivity of a Red-40 food dye. Using a spectrometer, the best wavelength to use for the analysis of this dye was determined to be 501nm. A series of dilutions were performed and the concentrations were calculated to find ‘E,’ the molar absorptivity, which was determined to be 18035 M-1 cm-1. Introduction The experimental behavior of…...
Potato Osmolarity Lab Report Ib
The pieces that will be placed in the solution with the lowest concentration of salt will have small weight loss. Finally, the pieces that will be placed in water (Nasal concentration O) will gain weight. This is expected because of the phenomenon of osmosis which was examined in a previous lab. Variables: Independent: concentration (%) of salt (Nasal) Dependent: mass (g) change Controlled: * shape and material of the beakers * size and weight of the potato pieces * volume…...
Surface Tension Of Water
The capillary rise method was used to measure the surface tension of aqueous solutions of sodium chloride and acetic acid. Molar concentrations of 0. 5 M and 1. 0 M for each solution were tested. The results were then compared to the surface tension of pure water to observe how solute properties affect the surface tension of water. The experimental results showed that adding acetic acid solute in water lowers the surface tension of water. As the concentration of acetic…...
The Chemistry Lab Experiment
To find the molarity of the unknown acid, first we had to create a standard solution, the solution we created was Sodium Hydroxide (NaOH). We wanted a 0. 1 molar solution of sodium hydroxide so to get this we had to dissolve 4g of NaOH into 1000cm? of water, but we didn’t want 1000cm? we wanted 250cm? so to work out how much sodium hydroxide would be needed you need to do the same equation to the number of grams…...
