neither man would expect the effect these elements could have on modern science‚ namely rockets. But creating a rocket is just combining these two gases in a closed environment‚ and one spark. This lab exemplifies just that what happens when the gases H2 and O2 are chemically combined with a spark. In this lab‚ the objective was to see how far a pipette filled H2 and O2 could travel. One half a centimeter of H2O was added to keep the gases inside‚ and make sure that only these H2 and O2 where included

Abstract This lab was focused on determining the optimal temperature of the enzyme amylase responsible for catabolizing starch polymers and to see how different temperatures affected the rate as well as how effectively the enzyme worked. To proceed with the experiment the group set up four different test tubes for each‚ bacteria and fungal amylase‚ and labeled them accordingly with different temperatures as well as different solutions . Then the spot plates were placed on the time and temperature

Introduction to Microscale Laboratory Niki Gharavi *‚ Minh Nguyen San Jose City College ABSTRACT: The objective of the experiment was to be introduced to working with the lab equipment‚ specifically heating and measuring‚ and to be able to create some of the apparatus that future experiments will require. Heating methods used were an aluminum block‚ a sand bath‚ and a water bath. The aluminum block heated most quickly while the others were more stable. Regarding the measurement of water‚ the less

Introduction Acid rain refers to a phenomenon in which "[precipitation] from the atmosphere [contains] higher than normal amounts of nitric and sulfuric acids". The precipitation that results in acid rain comes from the pollution emitted by human activities‚ such as factories‚ electrical power plants and automobiles. Two main pollutants are sulfur dioxide (SO2) and nitrogen dioxide (NO2)‚ which reacts with substances in the atmosphere‚ such as water and oxygen‚ to form acid rain. While rain water

Based on the knowledge I gained from the blubber lab‚ I discovered how homeostasis is maintained by feedback loops in regards to blubber. A negative feedback loop is a process where change is prevented and a certain set point is kept. In this experiment‚ the negative feedback loop was the blubber preventing the changing temperature of the thermometer. Therefore‚ blubber is a method of homeostasis‚ because it prevents the ideal temperature of the thermometer from dropping. Our data shows this as well

Purpose Name Due Date Clothespin Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally‚ muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the

Genetic transformation of Escherichia coli with pGLO (Adapted from: Biotechnology Explorer: Bacterial Transformation: The pGLO System. Instructors Guide. BIO-RAD). Objectives a. To understand one of the most commonly used techniques for introducing DNA into E. coli cells and its use in molecular cloning. b. To become familiar with the concept of using green fluorescent protein (GFP) as a molecular tag for studying gene expression in bacteria and other organisms.

The experimental membrane we used in this lab acted as a barrier in which only a small number of molecules can pass through. In this experiment we wanted to show the process of osmosis‚ in which water passes through the aforementioned barrier. Osmosis is critical to life because the process regulates

Electrostatic Lab What materials will you use? I will use the virtual lab and elements provided by the class What would you measure? I will measure the static electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching
