Koko was a Gorilla that was trained sign language at an early age by her primary caregiver Penny. Penny performed an experiment‚ testing to see if primates like gorillas can communicate in sign language with humans. The reason Koko was so special because she is the longest animal study in history. It infatuated the public when Koko was first in the public eye on the cover of National geographic holding kittens. Koko changed how people viewed animals‚ and got people to their emotions. Before this

Percent Mass of Copper in a Penny Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance‚ e is a constant called molar absorbency‚ l is the length in cm‚ and c is the concentration). Using Beer’s Law in this

In the Penny Cleaning Lab‚ my hypothesis‚ which stated that the lemon juice would be the best at cleaning the penny since it is an acid and acids are particularly good at cleaning metallic substances‚ was indeed valid. First‚ we started out with 1mL solutions of all the substances in the test tray. We dipped the pH paper in each solution for about a second and recorded the pH level for each substance. Before starting‚ we noticed that all the pennies were in some shade of brown‚ which I predicted

Percent Composition of a Penny Background Information: Post-1983 pennies have a copper jacket and a zinc core. We hope to determine the percent composition of these two metals. This will be done by reacting the zinc with hydrochloric acid to form zinc ions in a single replacement reaction. The acid reacts with the zinc but not copper. The reaction of zinc metal with the hydrochloric acid (HCl) produces zinc chloride and hydrogen gas. Safety: Wear your safety goggles and apron If you spill Hydrochloric

the U.S should stop making pennies. Pennies just cost to much to make‚ and they waste our time counting them over counters and at food service windows. Also‚ other countries have banned the penny and so should we. The penny costs more than its worth. Even though‚ pennies aren’t worth that much‚ the money wasted to produce them can add up to millions of dollars over time. It costs 2.4 cents to produce a single one cent coin.(Story) Taxpayers lose money every time a penny is made. It may not seem like

Penny Press Until the early 1800’s‚ newspapers in England and America were expensive and therefore exclusive to the wealthy and literate minority. On average‚ newspapers would cost around six cents per issue and were usually sold through subscription only. Readers would have to pay for a years’ worth of newspapers when first signing up for a subscription‚ and that cost could be a middle-class worker’s week’s wage. Most people could not afford newspapers and therefore could not receive daily news
