Erin Gaudet SCI-220-01 Title: Hair Lab Object: Analyze hair samples Procedure: Same as in lab handout Results: See attached data sheet Conclusion: This type of lab analysis is important to the field of forensic science because you could link a person to a crime. The removal of hair from the body often denotes physical contact between a victim and perpetrator and hence a crime of a serious or violent nature. Forensic scientists would find this lab useful because they would be able to determine

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

The refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water

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

Name:Date:Professor: Converting Decimal to Binary and Binary to Decimal (20 points) Instructions for the Binary Conversion Exercise: NOTE! LOG ON TO SKILLSOFT TO DOWNLOAD THE LAB INSTRUCTIONS AND START THE LAB. In computers binary code is the language that communicated between applications. Binary Code is a coding system using only digits 0 and 1 to represent a letter‚ digit or other characters in a computer. It is hard to imagine that huge and hard calculations are done on computers applications

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

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

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

Mineral Lab Paper Week One Mineral Lab Geology SCI/245 Axia College Mineral lab Paper The four requirements for minerals are that they must be naturally occurring in other words they must appear in nature something that that was formed by the earth and not man made. It must be inorganic which means I must not be formed from an organic substance like a fossil of any other living creature. It must have a specific crystalline structure that is formed from simple salts and complex silicates

Introduction The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Purpose The objectives of the lab were to help give us a better
