Three Questions Poster Rules to Follow Connecting Atoms to Evidence The Movement Question: Where are atoms moving? Where are atoms moving from? Where are atoms going to? Atoms last forever in combustion and living systems. All materials (solids, liquids, and gases) are made of atoms. When materials change mass, atoms are moving. When materials move, atoms are moving. The Carbon Question: What is happening to carbon atoms? What molecules are carbon atoms in before the process? How are the atoms rearranged into new molecules? Carbon atoms are bound to other atoms in molecules. Atoms can be rearranged to make new molecules. The air has carbon atoms in CO2. Organic materials are made of molecules with carbon atoms: foods fuels living and dead plants and animals. The Energy Question: What is happening to chemical energy? What forms of energy are involved? How is energy changing from one form to another? Energy lasts forever in combustion and living systems. C-C and C-H bonds have more stored chemical energy than C-O and H-O bonds. We can observe indicators of different forms of energy: organic materials with chemical energy light heat energy motion.
