To help students learn the appropriate text structures, text features, and language of informative/explanatory writing, teachers might begin with Talk-alouds. Below you will see two 2nd grade examples that focuses on the use of diagrams. These are a paired set of a Reading Talk-aloud and a Writing Talk-aloud.
functional group. n. An atom or group of atoms, such as a carboxyl group, in an organic compound that defines the structure of a family of compounds and determines the properties of the family. functional group. n.
CH 32M/30 28M Functional Groups A functional group is a defined grouping of atoms in an organic molecule.A given functional group exhibits a. characteristic set of chemical properties, which are largely independent of the rest of the structure of the molecule in. which it is found.As a consequence, an understanding of the chemical behavior of the functional groups allows one. to predict the reactivity of a wide variety of organic molecules.H 32M/30 28M Functional Groups A functional group is a defined grouping of atoms in an organic molecule.
