Macromolecules are very large molecules comprised by thousands of atoms. Their building brick are the monomers that form a macromolecule through the process of polymerization. Macromolecules are very important for living organisms. The most popular and important macromolecules for living organisms are the DNA, RNA and Proteins.    

Connection to Big Idea about evolution: Macromolecules like DNA play a key role in evolution, by containing the genetic code that makes each organism unique and being susceptible to the mutations that make organisms evolve.

Connection to Big Idea about the cell: The most common macromolecules in biochemistry are biopolymers like nucleic acids, proteins, carbohydrates and polyphenols. All living organisms depend on three macromolecules, DNA, RNA and Proteins which are found in cells and define their processes.

PLATON is a two-year European project launched on September 2016. It aspires to provide teachers and school communities with a coherent teachers’ training framework which will update their current teaching practices. More particularly, PLATON aims to offer an open and innovative training framework to teachers of primary and secondary education which will focus on:

  • Promoting student-centred teaching approaches;
  • Promoting a holistic interdisciplinary approach;
  • Support the use of online educational tools;
  • Support the meaningful collaboration between teachers of the same school.
