Particles > Structure and properties of matter > Structure and properties of organic molecules
Organic molecules are those that include a main chain of carbons connected to other carbons, hydrogen, oxygen and/or ammonia. Organic molecules even if they are rare on Earth, are very important as all living organisms are made up by them.
Connection to Big Idea about energy: Most of the energy used in Earth comes from fossil fuels mostly made of organic molecules. Living organisms use organic molecules to produce energy.
Connection to Big Idea about forces: Due to weak intermolecular (electromagnetic) forces, organic compounds usually have low melting points.
Connection to Big Idea about evolution: All diversity of life on Earth is made based on only 20 amino acids which in turn are made only out of four nucleobases (adenine, thymine, cytosine, guanine)
Connection to Big Idea about the cell: DNA is the hereditary material in most organisms, almost all is located in the cell nucleus.
