Lab reportTeiya Bilon August 16, 2011 Period 3 Physical Science This past week in lab, Mr.Kagawa divided us into groups to complete a toothpick bridge. Some of the requirements were that the entire bridge had to span 12 inches apart and 2 inches off the surface, with the support of piers. While we worked together with our teammates we got to know more about the people we are working with. We researched different structures of other bridges in class as well as at home. We also gathered information

Task 1: Task one was intended to build off of ideas implemented in the previous lab. More specifically formulating a V-I curve for the resistor circuit displayed in the prelab. Graph 1 shows the resulting V-I curve. Graph 1: V-I curve for the potentiometer. Like the previous lab, the signal was generated by a function generator and then sent through a potentiometer followed by a precision resistor in series. Figure 1 shows the LabView Block diagram that was used to record voltages

The use of 1 Microscopes Name: Khulud Abdulaziz Nazer ID: U00045236 September 23 2014 General biology lab Section: 13 T Instructor: Tasneem Obaid Introduction: Microscopes are instruments used to enlarge objects that are too small to be seen by one’s eyes. Microscopy is the science of the examination of small objects using microscopes. Technically we have two types of microscopes, the optical microscope which was first invented in late 1500s. It uses light and glass lenses (objectives)

Identification of Chemotaxis Protein Substrates in Thiomicrospira crunogena Introduction Thiomicrospira crunogena is a Gram negative, aquatic, colorless sulfur oxidizing, chemolithoautotrophic bacterium. Cells are spiral shaped 0.2-0.3 µm in diameter and 1-2µm long, some individual cells can reach up to 30 µm long (3). T. crunogena is motile via a singular polar flagellum. It is the first deep-sea autotrophic hydrothermal vent bacterium to have its genome fully sequenced and annotated

Aim The aim of this experiment is to investigate the effects of the angle between the conductor and the magnetic field on the magnetic force. Variables There are many variables in this experiment. The independent variable in this experiment is the angle between the conductor and the magnetic field, θ. The dependent variable in this experiment is the magnetic force, N (the reading of the electronic weighing balance, g). The variable that we must keep constant in this experiment is strength

Objective: To use a simple dihybrid cross of Zea mays with two distinct traits (height and colour), to characterize the segregation pattern and compare the fit of the data to the expected 9:3:3:1 ratio predicted by Mendel’s Laws. Why use corn instead of a random plant? Corn is fairly easy to breed in large quantities, which is advantageous when testing Mendel’s Laws because you can get huge amounts of data. It also grows quickly so it is easy to produce many generations in a short period of time

Elena Milovanovic Mr. Brian Gorodetsky Science 9 November 20th 2013 LAB Density Guiding Question: How does sugar/salt affect the density of water? Hypothesis: I think that the density will increase because salt and sugar add mass to the water, therefore increasing the density. For example, ocean water, it is more dense than the regular water because it isn’t pure like regular water, it has more salinity in it making it more dense. Notes: -A sugar and salt experiment. -We

Han Nguyen Partner: Trinh Pham and Elisa Ho ECE 444 Nov 9, 2012 Lab E: Application of Robots to person – kind Introduction: This was a two weeks lab. On the first week, we learned and played with some robots such as Roboquad, Robosapien and Tribot. We conducted some basic movements of each robot like turning left, right, toward and backward. Some robots can dance, which was really interesting. Moreover, we made some programs and let the robots memorize it. On the second week, we had to
