Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

Balloon Respiration Lab Introduction/ Background Cellular respiration is a process that releases chemical energy from glucose and other carbon-based molecules to produce ATP when oxygen is present. The formula for cellular respiration is C6H12O6+ 6O2= 6CO2= 6H2O. The process of respiration contains three main parts‚ glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The process of glycolysis takes place in the cytoplasm and is considered an anaerobic process which splits glucose into two

The Concentration of CO2 in the Atmosphere Introduction Carbon dioxide (CO2) is a colorless‚ odorless‚ non-flammable gas that can be produced by cellular respiration and burning of fossil fuels. Many types of industries such as breweries‚ mining ore and the manufacturing of carbonated drinks‚ drugs‚ disinfectants‚ pottery‚ and baking powder; utilize the CO2 gas (Appendix C). Recently Scientist proposed a theory in which CO2 concentration levels above 450ppm will lead to dramatic and potentially

Normally‚ people think CO2 is the chief source that affects global warming; however‚ methane is more dangerous than CO2. Among the total emissions in 2013‚ which was 6‚673 million metric tons‚ carbon dioxide took around 82%‚ while methane was 10%. It seems methane doesn’t occupy much of gas emissions. However‚ the potential power of methane weighs than CO2’s. The level of methane in the air has gradually increased by man-made activities. Methane’s live in the atmosphere is 12 years (EPA‚ 2010). This

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

Title: Effects of Light on Photosynthesis Introduction: Photosynthesis is the complex process by which carbon dioxide and water are used to make carbohydrates by using light energy in green plants. The objective of this experiment is to measure the rate of photosynthesis Hypothesis: The petri dish that is exposed to the most light and with the NaHCO3 solution will have the best results and the petri dish that is kept in the dark will have the poorest results. Material and Methods: 1. Get 4

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

the structure of my CO2 car‚ it is considered to be a rail car. There are many features that represent the car as a railcar‚ such as the narrow “rail” that connects the front axle of my car to the back. Typically‚ on a railcar‚ the wheels are located on the exterior of the car‚ unlike a shell car‚ in which the wheels are hidden inside the vehicle. Another distinctive aspect of my car is that the rail is very low to the ground‚ and the front‚ and back (which has to hold the CO2 cartridge) rises up

absorbance of salt‚ dead yeast cells‚ contamination‚ plate overgrowth‚ and the yeast cells drying from being under the vent in the incubator. In the future‚ we can do this experiment more effectively by having more than three weeks to perform the experiment as well as letting the yeast grow for more than twenty-four hours. As a result of having a longer amount of time to do the study and letting the yeast grow for longer than twenty four hours‚ we would get better results; yeast multiplies and divides
