LAB REPORT FOR EXPERIMENT 3 COPPER CYCLE OLANREWAJU OYINDAMOLA TUESDAY 27TH February 2013 Abstract This experiment is based on copper‚ to synthesize some copper compound using Copper (II) nitrate solution to obtain copper metal at the end. Changes of copper complexes when various are added and filtering out the precipitate by using Buchner funnel for vacuum filtration .The experiment started with preparation of copper (II) hydroxide and addition of copper oxide then addition of droplets

One of the main learning experiences of this lab is to learn the importance of calibrating a sensor. In most cases‚ a sensor will not have an output that is exactly what you need. An example of this is a strain gage. A stain gage gives back a voltage‚ but with that given voltage a distance can be found. Introduction: In this experiment‚ the QNET-MECHKIT was used. This board has multiple compact sensors that can be used for experiments. For this lab we will be using the strain gage to find the

Lab Report – Strong Example Problem/Question Does using a base coat before painting nails prevent chipping? Background Information When painting nails‚ some manicurists use a base coat before applying the polish. The purpose of a base coat is to help the polish stick to your nails more easily. Base coats also help to protect your natural nail from the staining effects of colored polishes. Ridge-filling base coats fill in the grooves and cracks in the nail to create a smoother appearance

Abstract: The reason for performing this experiment was to test the agnostic behavior coming from the male Betta fish. This experiment was conducting by taking a male Siamese fighting fish and placing its fish bowl next to a mirror so it would be able to see his reflection. We also exposed the fish to many others to see if the behavior was the same or different when placed next to: a goldfish‚ a female Betta fish‚ and a zebra fish. My hypothesis was supposed by this experiment and it was observed

Rising Water Secret Materials • • • • • • Candle and matches Pie pan or dish Juice bottle‚ jar or clear vase Water Food coloring Matches The candle flame heats the air in the vase‚ and this hot air expands. Some of the expanding air escapes out from under the vase — you might see some bubbles. When the flame goes out‚ the air in the vase cools down and the cooler air contracts. The cooling air inside of the vase creates a vacuum. - See more at:

Tensile Test Abstract The objective of this experiment is to test three specimens of different materials in a Tensile test machine and to calculate basic material characteristics such as tensile stress and Young’s Modulus. This report will explain in detail theory and procedures involved in such test and give all results obtained by group C2 on October 2013. Introduction Young’s Modulus‚ also known as Elastic Modulus is a material characteristic that represents stiffness and is defined as the
