## STEM Lessons - Model Eliciting Activity

In this Model-Eliciting Activity (MEA), students will evaluate wheel designs from different companies to determine which wheel is appropriate for the mission. Further 3D printing is integrated by 3D printing different wheel models which can be directly tested using a LEGO Mindstorms Robot or Simple Rubber Band Powered Sled and different Regolith Simulants for the Moon and Titan.

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. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

In this Model-Eliciting Activity (MEA), students will have the opportunity to analyze and organize data about tablet devices that their school is looking to purchase for daily use in the classroom.

In this MEA, students compare different tablet devices. They will be given empirical evidence and must organize this data to allow for interpreting key factors to determine which device is best suited for the client. Basically, students are given data and must use this information to make a recommendation to the principal about which tablet or device should be purchased with the school's funds. They will have to provide evidence to support their recommendation. This MEA is designed to help students with data that is collected from an investigation or a lab. In the past, students were able to generate data, but in this MEA they are given the data and asked to make it relevant.

## Original Student Tutorials Science - Grades K-8

Come with me as we select Scientist's Next Top Model! When does an abstract idea become a real scientific model? When the model appears in scientific journals and textbooks all over the world. Before a model can grace the cover of these high profile, peer reviewed journals and textbooks it must go through a rigorous process. How does a model go from an idea to a scientific model? What took me 2000 years I am going to make happen for one lucky model in just 15 short minutes!

Competition is tough and each model will have to showcase why they are able to represent themselves as Scientist’s Next Top Model.
