Magnificent Microscope Tradeoffs MEA:
Students will learn about the four types of microscopes (compound, dissection, transmission electron, and scanning electron) and compare them using the Model Eliciting Activity, or MEA, approach. Students act as a materials selection committee who will help a teacher decide which type(s) of microscopes are best suited for his classroom.
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.
