LAB 12 Introduction In this lab you will use the Wireshark packet analyzer to capture and display the control information and data stored in packets transmitted over a network. Wireshark collects network traffic data and creates files that display packet header information in a layered format like that used by the Internet model. These layers can be expanded to view details that may prove helpful in determining the source of problems that your network might be experiencing. Creating filters that

Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However‚ in this lab‚ acceleration was observed under different forces‚ other than just gravity. Therefore‚ depending on how strong the forces being exerted were‚ acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley‚ different masses were attached at the end of the string and the glider was allowed to move on the

ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

Collisions in Two Dimensions Abstract: This lab was conducted to investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this‚ both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity‚ allowing for future finding of momentum and kinetic energy values. By finding these‚ it was possible to determine which kind of collision took place. With low values of

Lab 2: Equipotential Lines and Lines Of Force Purpose: The purpose of this lab is to find the electric current when passing through conductors of different shapes and sizes. Also to gain a general knowledge of the laws governing the flow of current through extended conductors is another objective for this experiment. In this lab we are to experiment with the lines of force and equipotentials. We are also to find out vector field and the relationship between the lines of force and the electric field

Yak Lab Natural selection is the process by which favorable heritable traits become more common in successive generations of a population of reproducing organisms‚ and unfavorable heritable traits become less common. Natural selection acts on the phenotype‚ or the observable characteristics of an organism‚ such that individuals with favorable phenotypes are more likely to survive and reproduce than those with less favorable phenotypes. If all the offspring that organisms can produce were to survive

Energy Lab On November 13th‚ we did a lab to learn about energy. The definition of Kinetic Energy is energy of movement. The definition of Gravitational Potential Energy is energy in an object due to its positioning. The question that we had to answer was whether of not we could calculate the Gravitational Potential Energy and Kinetic Energy of various objects in different locations. To do this lab we had to first weigh the given objects. For this time‚ we weighed : a marble‚ a bouncy ball‚
