Materials Effect Our Life That Have Assisted Humans

The Paleolithic Era, translating to “old stone age,” references a time period over 2,600,000 to 12,000 years ago, in which man developed new skills for survival through the use of stone. The Neolithic Era, the “new stone age,” began around 10,000 BCE, introducing a more complex society where agriculture was a primary factor in everyday life. From the Paleolithic Era to Neolithic Era, there were many continuities that occurred. One continuity was the use of weapons and tools. For instance, in both eras, stone was used to make weapons for protection, food, etc. Although, in the Neolithic Age tools were more advanced and developed, they progressed based off of Paleolithic inventions, like the tools from both ages had spear tips, but different methods were used to come about their creations. In addition, while there were many continuities, the Neolithic man did not always agree with their ancestors choices. In fact, there were many changes that occurred from the two time periods. One drastic change the Neolithic man dealt with was choosing to live in permanent settlements rather than following with the Paleolithic way, living nomadic. For instance, the Paleolithic men were hunters and gatherers, indicating that they had to adapt to the natural environment of their location by studying the seasonal migrations of animals, the life cycles of plants, and many more elements. On the other hand, the Neolithic man lived in a time of general warming, increased rainfall, and a stable

The Bronze Age in Greece was a period of time in which their civilization flourished. They were a main power at the time and seemed to have everything they wanted in the palm of their hands. Many other civilizations have a period of time also known as the Bronze Age, however, the bronze age of Greece is widely known to be the most prolific and dominant in history. The Greece Bronze Age is estimated to have lasted from between 8th to 6th century BC to about 146BC. Nobody knows for sure the exact time period in which it began and ended. However, these are the dates that are most widely known to be accurate. No other civilization has been able to remain a dominant world power longer than this time period, which is why this is such an

The Neolithic Age began around 10,000 BCE. and lasted until around 800 BCE. During the beginning of this age much of the past ways remained very similar. It may have even looked positive for

     The Neolithic Period extended from 10,000 B.C to 3,000 BC. It is also called the New Stone Age, and many new advances and changes took place in this time. Unlike the nomadic life of the Old Stone Age, the New Stone Age was the dawning of settled life. People lived more towards lakes and rivers instead of caves, and tree trunks. This led to the change of the jobs of the society.

by 2000 BCE technology = ride horses and skilled pottery, used bronze, used iron and coal by 1000 BCE;

The Iron Age was a period when things were starting to be made out of iron. Iron was much stronger than bronze so that made it more valuable and wanted. The Assyrian empire was the first empire to have made iron weapons and tools. Both ages impacted the way that tools were made whether they were bronze or iron. Question 3: Greek and Roman

The Neolithic Era lasted from about 9,000-3,000 BCE. We are not exactly sure of when it started but this is the best estimate. The Neolithic Era was a period of human history when the start of agriculture arose and came before the first civilizations. The Neolithic Revolution took place in many different regions of the world. They where not that advanced so they made tools out of wood, stone and bone.

Chinese invented iron casting in the fifth century BCE. Tools made were used for decorative purposes in upper class, and also agricultural purposes. Iron weapons were developed for warfare.

The Paleolithic era began about 2.6 million years ago; this was considered the Old Age. The Neolithic era began about 10,000 BC where it was named the New Age. There were several differences that existed between the men who lived in these two ages. The Paleolithic man consisted of nomads who hunted and gathered their food to survive. Their hunting tools consisted of chipped and dull stones and wooden weapons. Their shelter consisted of huts and skin tents, and they were characterized as a tribal society. On the other hand, the Neolithic men were characterized by farmers who resided in permanent settlements, as opposed to wandering around. Their shelter was made up of bricks supported by timber, which seems to be a lot more durable

It has been confirmed by archaeological evidence that iron, made from melting pig iron, was developed in ancient china in the early 5th century BC during the Zhou Dynasty. during the Shang dynasty China went into a flourishing period for steel smelting. in the Han dynasty, private enterprise iron making was abolished and was monopolized by the state, creating iron smelting bloom. The first famous metallurgist in ancient China Qiwu Huaiwen of the Northern Wei dynasty, who invented the process of using wrought iron and cast iron to make steel.

In these two chapters of the Disappearing Spoon, the author, Sam Kean, focused on both the medical benefits to some elements, as well as their deceptive qualities. From silver to chirality to NASA, these two chapters are constantly surprising you, just like the elements discussed within them. Without knowledge of chemistry, it would be incredibly difficult to cure diseases, or even discern between deadly and helpful

The Natural Step provides a framework for considering the effects of materials selection on human health. Robèrt suggested that many human health problems, particularly those of children, result from materials we use in our daily lives. The extraction of resources such as fossil fuels and metal ores from the planet’s crust produces carcinogens and results in heavy metals entering the earth’s surface biosphere

Civilizations of the Stone Age were known for their use of stone implements, while the Bronze Age is signified by the use of bronze tools and technology. The Bronze Age is part of the three-tiered classification system of ancient civilizations described by Christian Jürgensen Thomsen: the Stone Age, Bronze Age, and Iron Age. The Bronze Age occurred at overlapping and slightly different times in various parts of the world. This is due in part to the limited availability of copper-tin ores. Certain places, like western Asia, did not see Bronze until trade brought this metal to the region. Notable civilizations during the Bronze Age were the Minoans, Mycenaeans, Hittites, and Egyptians. The Bronze Age dates from 3200-600 BC in Europe and 3300-1200 BC in the Middle East. The Bronze Age collapse occurred around 1200 B.C.E. What followed was a dark age of decreased literacy and technology and a significant reduction in population.

The first scholars that existed named the whole period of human devolvement the “Stone Age.” The stone age is divided into three periods which are Paleolithic which means the old Greek age, Mesolithic and Neolithic which is the new Greek age. The Paleolithic and Neolithic stone ages have many great differences and has changed greatly between the two periods.
