Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

Dylan McFarland 9/15/14 Honors Chemistry Richardson Lab: Measuring the Density of Pennies Pre-Lab Questions: 1. The equation that relates density‚ mass‚ and volume is: density = mass / volume. 2. All substances have unique densities‚ so if you are able to find the density of a substance‚ you can properly identify it. 3. We measure irregular-shaped objects with the use of water displacement because it would be nearly impossible to get the exact measurements

Light Microscopy Lab Lab write-up 1 Parveen Rajper Biology 101 Principles of Biology 1 September 29‚ 2012 Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult

density increases‚ concentration does as well. The density of a substance is something that stays constant‚ for solutions of material the density is expected to increase in direct translation to the concentration increasing. The theory surrounding this lab was to see in practice how density could be determined with displacement and then to determine whether the density does in fact increase directly with the concentration.

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

BIOMAGNIFICATION LAB REPORT AIM The aim of this lab is to model bioaccumulation and biomagnification through a food chain. MATERIALS 100 M&M’s Paper towel to lay M&M’s on 20 small cups labelled “zooplankton” 5 medium cups labelled “minnow” 2 larger cups - one labelled “eel #1”‚ and another labelled “eel #2” 1 bowl labelled “osprey” PROCEDURE The pile of M&M’s represents the phytoplankton population in a lake. The printed “M” on the candy represents the amount of DDT (in ppm)

Utilizing the Lab Results PS2200 - Criminal Investigation Unit 04 Assignment 01 As the lead homicide investigator for this case I had recently learned that the crime lab has concluded that the finger print that was recovered belonged to the boyfriend‚ they were from a piece of notebook paper found under the body of the victim. Interviews are conducted in criminal cases for the purpose of gathering information from people who have‚ or may have‚ knowledge needed in the investigation. (Swanson

Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for

Collision Lab Simulation Purpose: To study elastic and inelastic collisions in one-dimension. Background Information: Momentum: is a measure of mass in motion. It is the product of mass x velocity. Conservation of Momentum: in the absence of external forces‚ such as friction‚ the linear momentum of a system remains constant. Procedure: 1.
