AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

Laboratory Report 4: Invertebrate Animals Section: I Table: 6 Date: September 26th‚ 2013 Introduction: In our group‚ our task was to observe the selected four invertebrates and familiarize ourselves with their taxonomic levels through the organism’s mechanisms of feeding‚ motility‚ and reproduction. Our group used the prior knowledge we possessed about the Hydra‚ Rotifer‚ Gammarus‚ and Planaria organisms to complete the lab. We knew that all of these small invertebrates have a

Lab 4 Projectile Motion Sai Moua Purpose: The purpose of this lab was to define what the initial velocity of the ball when it is launched out of the pipe. Our next objective is to determine at what angle that the ball will be ejected at the maximum range. Lastly‚ we predict and confirm the range before we launch the ball at a certain angle. Theory: Projectile motion according to Dr. James S. Walker is defined as‚ “the motion of objects that are initially launched –or “projected”- and that

October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden

Title: The Mass of Quartz Purpose: To determine the density slope for water and alcohol and apply the understanding to determine the volume of a quartz sample without measuring the volume or calculating it. Hypothesis: The hypothesis of this lab was by using the density of alcohol we could calculate the density of a quartz samples. Controls and Variables: Independent variable: Volume of water and alcohol Dependent variable: The weight of the liquid or solid Controls: The volume of

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

Eric Scantlebury NT1310 Physical Networking Unit 4 Lab 1: New building – Tools and Wiring 4/8/14 Now that we understand the codes and standards needed to create this building‚ it’s time to put stuff in it. Our task at hand is to start wiring the building for a new computer science and electrical engineering labs. This building will have a lot of devices that need to be connected to the school campus network and we will need a lot of tools to do it. First off I think since our building is going

Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding
