The book COPPER SUN by Sharon M. Draper. Is an interesting story of a girl‚ named Amari‚ who lived in a nice village‚ with her family and friends until‚ she was kidnapped and sold into slavery. She has many emotions in this book. But I chose a few that I thought were the most important. Which are‚ frightened and happiness. One of the main emotions was frightened/scared. At the beginning of the book‚ Amari’s village was attacked. I know this because in the text it says. “Amari knew she should

Safety codes require ladders for mines‚ and the miners attempted escape through the ventilation shaft system‚ but the ladders were missing. The mining operation soon became known as “Camp Hope‚” for the next 69 days the dry‚ dusty‚ work site would be where rescue workers‚ officials‚ authorities‚ media‚ friends‚ and family of the trapped miners would call home.

According to The New York Times Company(2014)‚ “On Aug. 5‚ 2010‚ a gold and copper mine near the northern city of Copiapó‚ Chile caved in‚ trapping 33 miners in a chamber about 2‚300 feet below the surface”. At this time no one knew the well being or the nature of the situation that happened at the copper mine. During this time communication between employers‚ families’ members’

Amari is a 15 year-old girl who had a peaceful life with her villagers and her love‚ Besa; until pale strangers came in her village. They welcomed those pale strangers; stand on her village’s tradition‚ they always celebrate a party for the visitors.

reacted aluminum foil with a copper chloride solution‚ and determined the amount of metal that should be produced‚ given the amount of aluminum used. First‚ we obtained a piece of aluminum with a mass of 0.809 g‚ and reacted it with 100 mL of Copper II Chloride‚ after heating the solution. Then‚ we filtered out the copper separated in the reaction using filter paper‚ massing 0.751 g. Once all the solution was filtered‚ we massed the new filter paper filled with copper‚ after letting it dry overnight

Resistivity of Copper Wire of Different Lengths In this report I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment‚ one needs to obtain measurements with a high degree of accuracy‚ taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. The problem with measuring the resistivity of Copper wire is due to
