AIM: See the effect of temperature in anaerobic respiration of yeast by counting carbon dioxide bubbles. HYPHOTESIS: Anaerobic respiration in yeast will decrease as temperature increases. VARIABLES: Independent: Temperature Dependent: Rate of anaerobic respiration in yeast Fix: Volume of sugar solution (40ml) , Concentration of sugar solution, yeast mass (2g), volume of solution of yeast…
The boiling point reflects the strength of forces between molecules. The more tightly bonded the molecules are, the more energy is required to convert them into gases. These forces are called intermolecular forces. There are 3 types, dispersion forces, dipole-dipole and hydrogen bonding. The influence of these attractive forces will depend on the functional groups…
Purpose: The purpose of this lab is to test for enzyme activity, look at enzyme specificity, and how temperature affects enzyme activity. Time need to perform this lab: approximately 3 hours Preparation FIRST: Read the lab in its entirety TWICE before you begin. You will perform the experiment, write your lab report and include the…
Purpose: The purpose of this lab is to test for enzyme activity, look at enzyme specificity, and how temperature affects enzyme activity. Hypothesis: I believe that the room temperature activity will produce the most activity. Materials: 3% hydrogen peroxide, a household blender, potatoes (3 medium size potatoes, that are peeled and quartered), tap water, 8…
‘Water’ is one of the natures precious gifts to mankind. All living things consist mostly of water eg. the human body is of two thirds of water. It is clear, colourless liquid that appears blue when viewed through a thickness of 20 ft. The colour reflects not only from physical causes but also from suspended…
I. INTRODUCTION Fairchild Water Technologies was founded in 1980 by Eugene Fairchild. The company’s first product was a desalinator used by mobile home parks in Florida to remove salt from well water supplied to residents. As the desalinator became a huge success, the company expanded into the coastal region’s adjacent to the company’s headquarters in…

As stated in my research First hand, information and information from inmates that has been document in court filing. Hobby Unit…
Project Design Plan Everyone knows that water boils at 212°F, but does adding salt to a pot of water make it boil at a higher temperature? Being a person that cooks frequently at home, I wanted to test the debated idea that adding salt to my water will make it boil faster. One of my…
The macromolecule lab taught us how to set up a comparison to determine what a positive and negative test for a macromolecule looked like. Afterwards we used our positively tested samples as comparisons to determine whether or not the unknown food items that were brought in were positive for any of the four macromolecules. Statement:…
1. My hypothesis is that the resistance decreases as the temperature increases. I predict my results will have a negative correlation, and that as the temperature 2. http://www.gcsesciencemethods.co.uk/2014/05/thermistor-resistance-dependent-on.html http://www.nuffieldfoundation.org/practical-physics/effect-temperature-thermistor The first method contained a risk assessment as well as a choice of two methods, one with a digital multimeter as well as one with a…
For how many years has man asked the question, “what three items would you bring with you if you were stranded on a deserted island?” Well today that question will be answered. In the following essay it will be proven that an axe, a deep metal skillet, and very large spool of thick rope, would…
Over time, numerous applications for the addition of salt in water have been established and the process of adding salt in water has become a regular exercise wherever water has to be boiled around the world (Bradley, 2006). Purpose The purpose of this project is to study the implications of the addition of salt in…
