Title: Observing Bacteria and Blood- Lab #1 Purpose: Being able to learn how to correctly use a microscope and the oil immersion lens to be able to see the prepared slides. Also to learn how to prepare my own yogurt and blood slides. Procedure: First‚ set up the microscope. Clean the ocular lenses and objectives with lens paper. Then pace the prepared e slide on the stage and make adjustments. Turn the rotating nosepiece until the 10x objective is above the ring of light coming through the slide

G10 science By Freya Li Practical Investigation Resistance in Wire Aim: To investigate if the length of wire affects its resistance and find out how the resistance changes when the length of wire increases. Hypothesis: My prediction is that as the length of wire increases‚ the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire‚ which makes

Osmolarity TITTLE: practical of estimation of osmolarity in tissues by bathing samples in hypertonic and hypotonic solutions. INTRODUCTION: Osmolarity is the osmolar concentration of plasma and is proportional to the number of particles per liter of solutions shown as (mmol/l). It is derived from the measures Na+ and K+‚ urea and glucose concentrations. Since the volume of solution changes with the amount of solute added also it change in temperature and pressure‚ osmolarity we can say it’s

Hydraulic leak in Blowout Preventer (BOP) Accumulator identified during a pressure test prior to drilling out the shoe of the surface casing. The main hydraulic hose connected to the Annular Preventer is leaking noticeably where it is connected to the BOP. This could lead to the annular preventer failing during critical use when taking a kick and could

Sofia Dominguez 10-O 19/03/14 Effect of pH on germination of seeds: Design Practical Introduction: The term pH stands for Hydrogen Potential it is used to determine the acidity of a substance. The pH scale goes from 0 to 14. The values that are smaller than 7 indicate the range of acidity. Higher pH values are alkaline and a pH of 7 is neutral. Acidity is a function of the concentration of hydrogen ions (H+)‚ or protons. The strength of alkaline solutions is measured by the concentration of hydroxide
