Native Americans have been making pottery for tens of thousands of years. Hand built pots were made for practical purposes‚ artistry was not a consideration. Early containers were not decorated‚ except for the texture of the coils and pinches. Ceramics were initially made to carry water‚ to cook and store food‚ to store seeds and grains. They later made pots for artwork‚ rituals‚ burials‚ musical instruments‚ urns and countless other uses. They also began to decorate their pottery with symbols‚ birds

Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

on top of the shorter cup to prevent any heat loss to the air. Then the shorter cup was secured on a base with tape and a hole was drilled with a stir stick on the top of the taller cup to allow the stir stick and a thermometer reach the chemical reaction. With the calorimeter set up and ready‚ the experiment was ready to be conducted. The calorimeter was placed on a metric scale and tared. Then 2.5g of a substrate was measured out using a small scoop and placed in the calorimeter. A scale was used

foreign power‚ Native Americans are also regarded to have been subjected to significant change. When the Europeans first arrived in the late 1400s‚ they brought with them the intent of not only exploring to find India‚ but also to find gold and much more wealth. The Europeans made a mistake in their navigation causing them not to arrive in India‚ but rather what they referred to as the “New World.” The Europeans had stumbled upon the Native Peoples that occupied that place. The Native Peoples were

Flatland Reaction Paper Prior to reading this article‚ I never really thought of math to be this universal thing that could be applied over such a large horizon. I was knowledgable that‚ of course‚ everyone and everything could be eventually linked in some way or fashion to mathematics‚ but I was oblivious to how large of a spectrum it all really sits. Overlooking all of the sexist and biased opinions stated by Edwin A.Abott in this piece‚ he really opened my eyes to a different perspective of

The experiment was also demonstrated to observe how copper reacts while different reagent were being added. It was also demonstrated to practice the common laboratory

A substance that causes precipitation when it is added to a solution is called a precipitant. This can occur when an insoluble substance is formed in the solution due to a reaction or

The new immigrants suffered a tremendous deal of persecution and a poor quality of life living in the packed cities. Even though African Americans had been constitutionally declared citizens and equals‚ the South was still segregated and blacks couldn’t vote. As settlers pushed west‚ and the population grew‚ Native Americans were forced
