It was purchased by the Martin family in 1923 and they had taken over the farm and it has passed it on from generation to generation. Originally the farm was just dairy products‚ but Clifford Martin expanded the variety of products that they sold. They made fields of apples‚ pears‚ and peach trees. Honey Pot Hill Orchard was one of the first Orchards to allow people to go and

On April 17‚ 1975‚ Communist dictator Pol Pot led the Khmer Rouge into the the capital city of Phnom Penh‚ Cambodia. As people fled the capital‚ the Khmer Rouge took control of the Cambodian government‚ establishing their rule shrouded in blood and murder. Their goal: turn the country of Cambodia into a communist agrarian utopia. Although the Khmer Rouge only held power for four years‚ it was an incredibly brutal time. The Khmer Rouge murdered between 1.7 to 2.2 million people in an attempt to create

Title Freezing and Melting Point Objectives 1. To gain proficiency in constructing a graph and plotting data points. 2. To determine the freezing points of a compound from the graph of decreasing temperature versus time. 3. To determine the melting points of a known and unknown compound. Introduction Physical changes are the changes in the physical properties of a substance (Moore‚ Stanitski & Jurs‚ 2009). Freezing point is the fixed temperature at which a pure liquid converted into crystalline

communists and caused the downfall of their country’s economy. This includes the increase of poverty along with the increase of death rates. The two dictators we chose were Pol Pot‚ dictator of Cambodia and Idi Amin Dada the president of Uganda. Both were different ‚but much alike in certain ways. Pol Pot (Saloth Sar) Pol pot (aka Saloth Sar) was a Cambodian revolutionary who led the Khmer Rouge from 1963 to 1997. From 1963 to 1981‚ he served as the General Secretary of the Communist Party of Kampuchea

Results My unknown sample was number 18. I did three melting point trials‚ which resulted in a melting point range of approximately 120°C to 122°C‚ as shown in Table 1. I also did two mixed melting point trials using Benzoic Acid and Succinimide‚ as shown in Table 2. Percent recovery is 28.26 grams.

Holocaust and Pol Pot in Cambodia were both horrible events in history. They were both similar and different in many ways. In both events victims were sealed from the outside world. Women‚ men‚ and children were being overworked and starved. And even after all the hard work thousands of them were being killed. Both leaders had different plans‚ but one thing they both had in mind was genocide. In both events the victims were being sealed off from the outside world. In Cambodia‚ Pol Pot wanted all culture

In the article‚ Why are Starfish ‘Melting’‚ by Jane J. Lee‚ they explain that millions of starfish‚ for the past year and a half‚ have had a lethal virus which has turned them to white goo. The virus is a kind of parvovirus‚ which is “the group of viruses that cause gastroinintestical problems in unvaccintated dogs.” Although this virus is killing many starfish there isn’t very much that researchers can to to try to stop it.
