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

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance‚ then plotting heating and cooling curves and analyzing them. Data that you collect will represent the

Butter lab 1 Introduction: While doing this experiment we used 3 terms. We used cream‚ butter‚ and butter milk. Cream is unhomogenized butter. Butter is what we got after the lab was finished. Butter milk is the milk around the butter after it is homogenized and it is thicker than normal milk. If we shake the cream in a jar than will it turn into butter? If I shake the cream than it will turn into butter because it will homogenized. In this lab you will shake a jar of cream and see if will

Darwin’s Finches Lab In this inquiry lab‚ we explored natural selection using a laboratory. We wanted to see what was the effect of the type of food available on the frequency of different types of bird beaks. Our hypothesis was that If the type of the food available changes‚ then the frequency of beak types will change‚ because birds with beaks more suited to the available food will be more successful over time. Variables: Independent Variable: type of food available

Michael Castelli Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of

There are many missions set up to explore our solar system and the rest of the universe. Apollo 11 is a great example of exploration. Its primary objective was set by President John F Kennedy when he said‚ “we shall send to the moon‚ 240‚000 miles away from the control station in Houston‚ a giant rocket... carrying all the equipment needed for propulsion‚ guidance‚ control‚ communications‚ food and survival‚ on an untried mission‚ to an unknown celestial body‚ and then return it safely to earth”
