Differentiation Instead of the Molecular Models 11 x 17 Placemat, provide your students with the 4.4 Alternative Flame Molecular Model Placemat to use as the placemat for their molecular modeling. Have students place the models in the appropriate locations on the flame system placemat before, during and after the chemical change. Modifications Tips Laminate the Molecular Models 11 x 17 Placemat. These will be used multiple times in each unit. During the molecular modeling activity and animation, focus on how matter and energy are conserved through the chemical change. This is the main goal of the activity! Extending the Learning Lesson 5 will include opportunities for students to learn about the combustion of other fuels, including methane, propane, and octane. Curious students can look up the formulas for these fuels and make molecular models of them.
