Do Now: GET A WHITEBOARD AND MARKER
On a whiteboard, draw a graph that represents the energy changes during an endothermic reaction. You know this...energy at start, energy breaking bonds, energy making bonds. Our last driving question: "Why do some reactions give off heat and others take heat from the surroundings?" Make a model on your whiteboard showing an endothermic reaction and exothermic reaction. Include: Atoms, bonds, energy in, energy out, chemical reaction Task:
New Driving Question: What makes some bonds stronger and some bonds weaker? Why do atoms form bonds anyway? Task 2:
