There are several allotropes of carbon of which the best known are graphite, diamond, and amorphous carbon. The physical properties of carbon vary widely with the allotropic form. For example, diamond is highly transparent, while graphite is opaque and black. Diamond is the hardest naturally-occurring material known, while graphite is soft enough to form a streak on paper. #Glogster #Carbon
Both diamond and graphite are made entirely out of carbon, but they differ in how they are structured. Carbon atoms in diamonds are arranged tetrahedrally, whereas carbon atoms in graphite are layered in honeycomb arrays. This difference makes diamond the hardest natural mineral and graphite one of the softest materials. ~ SuperFlash Elements for iPad! https://itunes.apple.com/us/app/superflash-elements-periodic/id931215207?mt=8
This is a foldable to either review or introduce the Cycles of Matter. It includes diagrams of The Water Cycle, The Carbon-Oxygen Cycle, and The Nitrogen Cycle. It also provides definitions and key elements to each cycle.
Most students learn about atoms and characteristics of the elements on the periodic table in middle and high school science classes. Consider choosing a simple atom, such as carbon, to represent through a hanging mobile 3D model. Although simple in structure, carbon and compounds containing carbon form the basis of all life. Making a 3D model of a...
