The main ingredient in Silly Putty is polydimethylsiloxane. Polydimethylsiloxane has viscoelastic properties, which means when it is in high temperatures, the putty runs. The putty can be torn apart because of the weak Hydrogen bonds. It was accidentally made by scientist James Wright with Boric Acid and Silicone Oil. A Silly Putty-like material will be used in space suits.

The article I read was about minerals. Minerals are put into 7 major groups and 7 minor groups. Minerals are natural occurring, inorganic solids which possesses a characteristic internal atomic structure and definite chemical compound. Minerals have distinctive properties and characteristics such as hardness, streak, color, cleavage, luster, specific gravity, fluorescence and miscellaneous properties. Minerals can be found anywhere and they can be identified using all of the physical properties.

This article was about minerals. A mineral is a naturally occurring, inorganic solid which possesses a characteristic internal atomic structure and a definite chemical composition. They have distinctive physical properties such as color, crystal form, cleavage, luster, streak etc. Minerals have mineral groups that are formed by their similarities. There are seven major groups and seven minor groups. Minerals can be identified by using all of the physical properties you find. They can be found everywhere. Minerals can form into crystals if they get into an arranged order of atoms. They can also form into rocks by a gathering of sediments, cooling and hardening of magma, and pressure from earth. Minerals are very unique substances and they can form several interesting things.

# data[].attributes.body
Minerals are organic and can be found in nature. Overall there are twelve groups of minerals and each group has certain characteristics which lead to how they are grouped together. Some of the mineral groups are  a lot alike, as they can bond together easily or they are just very similar. The groups are: Native elements, Borates, Carbonates, Halides, Nitrates, Oxides, Phosphates and Arsenates and Vanadates, Silicates, Sulfides, Chromates, and Sulfosalts. Many of these groups are based on the silica tetrahedrons.

018 - Thermal Conductivity In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized electrons. Heat can be transferred through insulators using phonons.
