The Stone Age was the period of time in which we discovered and began to use tools and materials made from stone.
-
This was when people began taking wood, from trees, and then rocks that they could find and making tools and materials from them.
-
This was a material that was discovered most likely on accident, and was used to cook, scare animals away, keep warm, etc. and the temperature of flames is between 750-1,100 degrees F.
-
Pottery, namely bowls, were starting to be made from clay. You could harden the clay at a low temperature of 1,950 degrees.
-
Kilns are machines used to cook clay and make it into a ceramic. It can reach up to around 2,552 degrees.
-
Bricks are a composite material made similarly to clays. High fire materials like that can be achieved at around 2,380 degrees.
-
Copper was the second metal discovered and used after gold. It has a melting point of 1,981 degrees F.
-
The Age in which we discovered bronze. The melting point of bronze is about 1,742 degrees F.
-
Bronze Alloys are alloys made of bronze and another material, like copper for instance. It is made to make bronze stronger. Like before, the melting point is around 1,742 degrees.
-
The time in which we began using iron.
-
Iron metal was obatained when we discovered its ore. It's melting point is 2,800 degrees F.
-
These occurred around the 1900. We began taking things like iron and mixing them with other metals to create powerful steels. It has a melting point of around 2,750 degrees F.

Sustainability involves masking sure that the society you live in can sustain itself. It involves making sure that all the residents within the society are living a meaningful and healthy life. The resources used, the economics, and the environment need to be healthy and sustainable so the the society can continue to thrive and grow in a healthy way that is not damaging to the environment and the residents within it.
