Do now activity What is the difference between an element and a molecule? What are the 4 macromolecules? Which macromolecule is made of fats? Which macromolecule is made of amino acids? Which macromolecule is made of sugars? Which macromolecule is made of nucleotides?

Section 1-4 Macromolecules Unit 1—Molecular Biology Essential Question How are macromolecules formed from the essential elements of living systems? Learning Targets Explain how macromolecules are formed from individual elements (Carbon, Hydrogen, Oxygen, and Nitrogen). Explain how the sugar molecules from our food are broken down into elements (C,H,O) and used to make other macromolecules. Section 1-4 Macromolecules

structure Monomer Polymer Macromolecule

structure Monomers -- simple molecules Polymer -- linked monomers Macromolecules -- large polymers Use plastic “baby” toys to demonstrate. The monomers can be the same like in a watch band or different like in a bead necklace.
