Density Lab Partners: Betty Alcaraz Date: 9/10/13 Teacher: Wright Class: 7th period Introduction/Purpose: To determine the densities of unknown substances. Pre-Lab: 1. Which is heavier‚ a pound of feathers or a pound of lead? a. A pound of lead. 2. What is the density of a mineral if 427 g of the mineral occupy a volume of 35.0cm3? b. 12.2g/cm3 3. The water level in a graduated cylinder stands at 20.0 mL before and at 26.2 mL after a 16.74 g metal sample

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.

Jeanine Campa Biology 101 10/20/2010 Ecology-Interspecific Interactions Lab Intro: Ecology is the study of how organisms interact within their environment. Every species interacts with its surroundings‚ whether it’s within their populations‚ community‚ ecosystem‚ etc. In this lab‚ we will be comparing two different species and how they grow alone as well as together‚ in the same environment. More specifically‚ in this lab‚ we will be dealing with one of the most important ideas in ecology‚ the

In each station there was a positive and a negative control. If the substance was the same as the negative control then it was negative. If the substance was the same as the positive control than the substance is positive. In the first lab we did the Paper Spot test‚ one would have had to apply the substance on a cardboard like paper. If it looked oily it was the biomolecule called lipid. The result of test one was it stayed the same‚ it did not turn oily and was clear. Next was the test

Biochemistry is the chemistry of biological systems. The practical component of biochemistry is aimed at developing your interest in and understanding modern biochemical and molecular biological experimentation. The techniques learnt in the biochemistry lab will be applicable to all life sciences. THE OBJECTIVES OF THE BIOCHEMISTRY LABORATORY INCLUDE: (1) Learning the theory behind the techniques and biochemical pathways (2) Learning the physical skills and techniques of modern experimental biochemistry

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then

Multimedia Graphic Bell Labs: A Hive of Invention But we idealize America’s present culture of innovation too much. In fact‚ our trailblazing digital firms may not be the hothouse environments for creativity we might think. I find myself arriving at these doubts after spending five years looking at the innovative process at Bell Labs‚ the onetime research and development organization of the country’s formerly monopolistic telephone company‚ AT&T. Why study Bell Labs? It offers a number of lessons

Introduction The photosynthesis lab is designed to quantify photosynthesis‚ enabling a number of variables to be tested for their effects on photosynthetic rate. The production of oxygen‚ is used as an indirect measure of photosynthetic activity.The lab allows the examination of the effects of different wavelengths of light on photosynthetic activity. The other aspect of the lab includes Paper chromatography‚ which is
