In this MEA students work collaboratively to analyze concrete and cement formulas based on research collected. Students are required to apply knowledge of chemical composition and determine which formula would be best to use in a given situation. In the first letter, students are asked to rank different concrete mixtures. In the second letter, students are asked to analyze a series of cement mixtures. Then, the students must determine which cement mixture is the most appropriate for rebuilding a coastal area. Students must also investigate hurricane building standards to make the most appropriate choices.

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.
