Lab 5.3 SPRINGS- HOOKES LAW Group member: Submitted by: Submitted to: Class: Due: Lab 5.3 SPRINGS- HOOKES LAW Purpose: To study the characteristics of a spring. Hypothesis: With an increase in weight there will be a directly relatable increase in spring length. Additionally each spring will increase to different expected lengths. Materials: -Light spring -Dense spring -Brass spring -Masses -Ruler

Justin Von Bargen EN1420 Composition II 24 July 2013 Religious Failure There are many different religious texts in the world‚ but none of them have substantial proof that the events even happened. All these religions have different stories about how the earth came about and how life was created‚ but science has been the only source for proof of how the earth and everything on it was created. I – Lack of Evidence: "And We did certainly create man out of clay from an altered black mud

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic

Experiment E: Post lab Natasha Buckiewicz (130361780) IA: Matt Halloran Due: November 26‚ 2014 1. This experiment followed GCP number 8 which is reduce derivatives. This experiment did not use unnecessary derivation since the reaction was not modified in any way. No additional reagents were required so it did not generate a lot of waste. 2. Safer solvents and auxilaries (GCP #5) was not used in this experiment since the experiment used a solvent to complete the reaction. The reaction used both

| Adelaide High School | [Osmosis Practical Report] Abstract: | The purpose of this investigation is to see if the concentration of Sodium chloride (NaCl) solution will affect the mass of the potato cylinder hence the rate of osmosis. This can be done by placing 5‚ identical in length (3cm) but different in weight‚ tubes of potato in 5 different beakers. Each containing an altered NaCl concentration. The concentrations used in this experiment were‚ 0%‚ 2%‚ 10%‚ 15%‚ and 26%. Potatoes

Lab #3: Stoichiometry of a Precipitation Reaction October 14‚ 2014 Abstract: The purpose of the lab‚ Stoichiometry of a Precipitation Reaction‚ is to be able to calculate the amount of a second reactant we need to react with the reactant one. You must calculate the amount of the second reactant using stoichiometry to figure out what amount is needed. After the amount is calculated‚ you then can add it to the first reactant and it will give you a full reaction. To figure out what you

Extended Experimental Investigation | May 28 2013 | Drosophila melanogaster lab experiment Question: How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Hypothesis: If certain phenotypes are expressed in the offspring from the cross of certain Drosophila‚ then the determination

Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration‚ in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves‚ without input of energy‚ across a semipermeable membrane separating two solutions of different concentrations. Although osmosis does not require input of energy‚ it does use kinetic energy and

Experiment #4 (10/31/14) Lab Review Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life. These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes
