The results of this experiment showed that there was little to no change in the physical properties, which include the flake surface color or cortex color. There was only a slight change to the surface luster, but that could even be from the quality of the Knife River Flint and not a result of heat-treating it. The results of the structural changes were a little more promising. There was a noticeable change in the knappability of the heat-treated Knife River Flint compared to the raw/unaltered samples. Neither the hypothesis nor the null-hypothesis that were laid out in this paper was fully proven. There were aspect of both that were correct. There was only a noticeable change in the structure of the Knife River Flint, so that part of the hypothesis is true, while there was not noticeable change in the physical properties of it, which is true for the null-hypothesis. The hypothesis and null-hypothesis where not proven or disproved fully. I think this experiment could eventually prove the hypothesis right or wrong; further steps would need to be taken. Increasing the time and temperature could potentiality yield better results. If that were the case then the use of a kiln would be need as they can reach high temperatures then a household oven can. …show more content…
The experiment laid out in this paper was a simple one that only looked at the most basic characteristics of thermally altered Knife River Flint.
It was kept this way because of the materials that were available. This experiment was done in an informal setting and a not professional one. It was also kept simple because of the novice knapping ability and knowledge that I possess, since I am currently learning and developing the ability to knap. This was also my first lithic experiment that involved the heating of stone. I still have a lot to learn to further my skills with flintknapping. This experiment has a lot of potential that I would be intrigued to work on in the future to further tease out

N. Scott Momaday wrote these lines in his 1991 book of poems, In the Presence of the Sun: “In the shine of photographs / are the slain, frozen and black / … In autumn there were songs, long / since muted in the blizzard.” In this poem called “Wounded Knee Creek”, Momaday depicts the aftermath of Federal and Native American conflict at the Battle of Wounded Knee. He reminds the reader of how the event and loss of native life are remembered solely through these photographs of the dead and lost. Momaday’s work represents the Western tradition of artists using their art to memorialize and remember the past peoples and places that have been transformed, built up, and destroyed through government institutions of the West. It is this remembrance of
It seems that in the 21st century and even during the colonizing of America, the interpretation of Native Americans is and had been that they were savages and live a barbaric lifestyle. That they had no order or way of life. When presented with the topic of Native Americans and Colonists in the New World, it is easy to assume warfare and bloodshed amongst the two parties. That the Colonists were constantly in mini battles with the Native Americans. It is also easy to assume that the land in the New World was unsettling to the eyes. This is due to records from the colonist times, calling the lands “wild” or “wildlands”. In Robbie Ethridge’s book Creek Country, she tries to debunk these interpretations mentioned above. She does so by using an
What episode or even seems to be the one that precipitates the action? (In other words, what is the trigger point?) What was the state of affairs before this?
Have you ever thought about driving over a suspension bridge held up by cables? That’s what the Mackinac Bridge is. With the building of the Mackinac Bridge there has been many positive effects that have come out of it.
In the matter of seconds the people of Flint had their lives take a turn for the worse. Once what happened had finally been brought to the public’s attention, the word began to spread very quickly about the water that had been found to contain lead and was a clearly a threat to the people who had consumed it. People started talking about what could have been going wrong, and what could have caused this to happen. That is what lead me to this article that goes into the assumptions of Governor Snyder lying about what he knew about the water and when he found out. Even though this article is about the city of Flint, it has three different types of audiences. There is the direct audience which is obviously the people of flint. People who read this article and are able to help to are considered the indirect audience. Lastly the audience of people nationally hearing and reading about this situation. For that reason this article has relevant pictures, such as pictures of the discolored water. This helps it to be readable for all types of readers. It also gives the audience a glimpse at the current situation. In this article, the rhetorical devices of ethos, pathos and logos are used to make creditable, have an emotional connection and give evidence of the crisis.
The Flint water crisis would be one of the most critical things today in michigan. It’s critical for young children not to get lead exposure they should be screened from the lead and lead levels in children's bodies as well. (National Center for Healthy Housing) The water needs to be treated with which it will increase the corrosiveness and potentially further erode any lead piping. (Duke) The People in Flint are a facing with not be able to drink water, and shower. All of these things that happened are critical factors of what is happening in the Flint water crisis today.

3. Why are the crucible and lid heated at the beginning of the experiment before being weighed?
The Mississippi River is one of the world 's extraordinary rivers. It is the longest in the United States, more than twenty-three hundred miles in length, as it structures the outskirts of ten states, just about bisecting the mainland (Currie,2003, 8). This waterway has a long history also, and it has touched the lives of numerous individuals. The Mississippi is said to start at Lake Itasca in Minnesota. In 1832, pilgrim Henry Schoolcraft named this lake, not after any neighborhood Indian name, but rather from the Latin words for "genuine head" which are veritas caput abbreviated to "Itasca" (Currie, 2003, 4). In any case, much sooner than its source was named it was a navigational waterway. The Indians who initially lived on the banks of the stream were known as the Mississippians. From 800 to 1500, these people groups utilized the waterway for exchange. They dug out
The Muskegon River is 216 miles long; it’s origin is in Roscommon County it flows in a southwest direction and empties into the Muskegon Lake which then flows to Lake Michigan. Early settlements and cities in the United States were generally built near oceans, lakes, and rivers for the commence and transportation advantages. The city of Big Rapids was founded for its geographic location along the Muskegon River in the 1850s. At a time when logging was a main industry in Michigan, the Muskegon River was used as an artery to move logs downstream from Houghton Lake to the mills in Muskegon. Lumbermen called the swift currents and rapids in the area “the big rapids,” which was adopted as the city’s name. Today the logging business
If you are interested in bird watching, the Connecticut River is the place to go. With eagles, ospreys and scores of other species, enthusiasts can see them up close and personal under the guidance of the RiverQuest crew and a set of high powered binoculars provided by the staff. The RiverQuest boat has two open decks along with a heated interior with large windows to keep you comfortable when the winds get too chilly outside. The thoroughly knowledgeable staff of Captain Mark Yuknat along with wife Mindy, crew Scott and Cathy provide a wealth of information related to the various species of bird, habitat and environment.
In 1969, the Cuyahoga River (in Cleveland, Ohio) caught on fire because it was “polluted from decades of industrial waste.” Furthermore, after the river set on fire for the final time, the government of Cleveland stepped in to stop the factories’ water runoff into the river. They no longer allowed the factories to have overflow into the river, Although the main problem was fixed for the present, another problem was creeping up: runoff from large industrial farms. Pollution is a serious matter, because if our world gets polluted, it will no longer be safe or healthy to live. The way people eat has a big part in pollution. If they eat locally, or at least try to, they can help cut down on out pollution. The method of Local Sustainable farming
On this day, the FBI begin investigation into the Flint Water Crisis in Flint, Michigan; but what was the Flint Water Crisis? What started it? Does it still affect us today? These questions are still being asked, but some people may have the answer.
The purpose of this project was to discover how the pH level affects corrosion rate. The hypothesis was if the pH level affects the corrosion rate, then the lower the pH level is quicker the corrosion rate would be. This will happen because liquids below the pH level of 7 possess stronger acidic attributes. The effect of pH level on corrosion rate was determined by depositing a copper penny in each of three plastic cups, and then three different liquids by their pH levels, were assigned to be displaced into each cup formulating a chemical reaction to be observed. The results collected during this investigation contradicted with the intended result, this experiment was conducted to determine corrosion rate; Dana Puti Vingear (pH level: 4.5) 4 2/3 days, Tropicana Orange Juice (pH level 3.88) 6 1/3 days, and Sprite (pH level: 3.4) 8 days. The results showed that the hypothesis was refuted. This happened because the preconceived idea was that the liquid with the lowest pH level; Sprite, would have the quickest corrosion rate. Dana Puti Vinegar had the quickest corrosion rate proving the statement wrong, it was discovered that it contains ethanoic acid; acid containing twice the amount of carbon dioxide than a regular acid. To further understand this topic, future research could include; how does the amount of liquid incorporated affect the corrosion rate, how does the temperature of the liquid affect the corrosion rate, and how does the purity of iron affect the corrosion rate?
The use of stone tools is an aspect they got right in the movie, making and sharpening stone tools which were later used for hunting and fighting predators who want to take away their food. The weaker group gives up their food. It is the survival of the fittest.
Operation: A hydrometer is a measurement instrument used to measure the relative density of liquids, the ratio of a density of a liquid to the density of water.
