In this Model Eliciting Activity (MEA), students will use their knowledge of the organization of the periodic table and the basic properties of atoms to determine which elements should be used to develop compounds with two atoms of different elements. Students must determine the number of protons, neutrons, and electrons in a neutrally charged atom of an element using the periodic table. They must also determine which elements will likely bond together using their location on the periodic table. Students completing this MEA will develop two short essay responses to a client in the scientific industry.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.
