Driving questions Photo Credits: Ethanol: FableVision Water Glass and Logs Burning: Hannah Miller, Michigan State University Open Lesson 5.2 Organic vs. Inorganic Presentation. Show students Slides 2-6 to zoom in to water, ethanol, and wood from the macroscopic down to the atomic-molecular scale. Tell students that the materials are similar in the kinds of atoms that they are made of, but that they are different in the kinds of bonds between the atoms: ethanol and wood have high-energy C-C and C-H bonds; water does not. Tell students that wood is a mixture of many substances, and that cellulose is the most abundant of these substances. Show students the Slides 7 and 8 to point out that the atoms found in the three materials are similar. Show students Slides 9-11 to point out that the bonds between the atoms are different: ethanol and wood have high-energy C-C and C-H bonds, and that water does not. Why can some things burn while other things cannot burn? Why does ethanol behave more like wood than like water?

Water molecule (H2O) Ethanol molecule (C2H5OH) Chemical Energy Energy found in the bonds of molecules. C-C and C-H bonds means molecules have available chemical energy. So which materials have available chemical energy? Cellulose (C6H10O5)n Photo Credit: Craig Douglas, Michigan State University Show students Slides to contrast materials that burn (fuels) with materials that do not burn. Explain to students that the difference between the two groups of materials is in the bonds, not the atoms. Show students Slide 17 to introduce and label these two types of materials. Tell students that in this context, organic is a chemical term - it does not mean “natural” or refer to a certain kind of food. Show students Slide 18 to point out that food and the bodies of humans and other animals are made largely of water and organic materials: carbohydrates, fats, and proteins. Tell students that they will return to the chemical composition of these organic materials in later Carbon TIME Units.
