Introduction The moons surface is riddled with craters‚ formed by many asteroids smashing into its surface. These crater differed greatly in size‚ making it easy to assume that the larger the asteroid‚ the larger the crater. While this is partially true‚ it is not the only factor that controls crater size. This experiment will be exploring the asteroids speed and how this effects a craters size. Aim This scientific experiment was conducted to find how the impact speed/energy of an asteroid affects

Isabel Wilkerson’s The Warmth of Other Suns: The Epic Story of America’s Great Migration delves into the great exodus of Southern blacks to the North from World War I to the 1970s. While this in an already acknowledged period of Southern and American history‚ the book is still an important source in Southern studies. For one‚ the book provides students with three extensive firsthand accounts of the period‚ something they may not have been exposed to before. Meanwhile‚ some may argue that since a

Methods We began this experiment by turning the Spectrophotometer to 605 nm absorbance‚ and setting up each of the tubes as stated in Table 7-2*‚ ignoring the DPIP until the rest of the sample was set up. Once all of the samples were set up accordingly‚ we blanked the spectrophotometer‚ and added the DPIP to the sample right before‚ inverting the sample and taking a reading at the Zero time mark‚ and placing the sample in the designated light apparatus‚ Sample 1 was wrapped in aluminum foil to

In our experiment‚ we will be testing three different proteins to see if they denature at the same temperature. A protein is a molecule containing amino acids created in ribosomes that have many functions‚ including being an enzyme and transporter‚ structuring‚ translating genetic information‚ and serving as a channel for charged molecules to pass through the cell membrane. As a molecule‚ a protein is shaped like a coil (Food Science Basics 2014). Denaturation is when a protein’s shape changes due

Investigation into how the focal length of a lens affects the temperature at the focal point Research & Rationale: In my project I will be looking in to how different lenses with varying thicknesses and therefore focal points magnify and intensify light passing through it. To do this I will be measuring the temperature of an object behind the lens‚ at the focal point. The study and research of lenses was not part of the course this year‚ so I thought it would be more interesting to study a new

ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing surface area increases the reaction rate‚ and increasing temperature also increases the reaction rate. Temperature is the measure of the average kinetic energy of

How can the specific heat capacity of water be used to regulate temperature? Specific heat capacity is the amount of energy needed to increase the temperature of an object by 1˚C. The formula that uses specific heat is Q = mc∆T‚ where Q is heat energy‚ c is specific heat‚ and ∆T is the change in temperature. The amount of heat energy depends on the mass‚ or the size of an object‚ and the specific heat capacity‚ which depends on the substance it is made from. The specific heat capacity of water

Nicole Reardon Biology 1520‚ Section P2 Effects of penicillin and temperature on the growth of Escherichia coli Abstract Bacteria growth is known to be either augmented or impeded by a number of various factors; in this experiment‚ our group tested how E. coli is affected by penicillin as well as how different temperatures can affect bacteria growth. We know that antibiotics are generally specialized against certain types of bacteria—more specifically‚ some are most effective against Gram-negative

EFFECT OF CHANGES IN TEMPERATURE AND SDS CONCENTRATION ON THE STRUCTURE OF BEETROOT CELL MEMBRANES. Introduction Cellular Membranes or cell membranes are biological membranes that separate the interior of a cell from the outside environment. Cell membranes are selectively permeable to ions and some molecules and control the movement of substances in and out of the cell. (Danyk‚ 2013/14) Cell membranes separate and organize chemicals and reactions within cells by allowing selective passage
