How Long is Your Music Lesson?:

In this Model Eliciting Activity, MEA, students will be required to rank musical instrument lesson packages based on the price, the number of minutes of practice each week, and the quality of the instructor.

Part of the task involves students figuring out the elapsed time of the lessons based on their start and stop times. They will also need to figure out the total weekly cost of the lessons based on the number of lessons offered per week and the cost of each lesson based on its length.

The twist will require students to determine whether or not to revise their ranking based on new information about the cost of instrument rentals per lesson and the class size of each package.

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 process. 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.

Scheduling a School Day: Creating your own classroom schedule.:

In this Model Eliciting Activity, MEA, a group of students has been chosen to help create the classroom time schedule for the school year. The students will have to use the parameters set forth by the teacher and principal, as well as their own expertise about how they learn best, to create a schedule for the school day that includes all subjects and works around time set aside for lunch and special areas. Then the students will have to adapt the schedules they created to accommodate additional considerations by the teacher and principal. This MEA will require students to use their math skills to measure time intervals and their ELA skills to write a letter justifying and explaining the schedule they created.

Transportation Choices:

In this Model Eliciting Activity, MEA, students will determine which mode of transportation is best for a traveling sports team. They will have to calculate the total cost for each type of transportation and consider the comfort of travel. In the "twist," students are provided with more information including customer service rating of transportation as well as an additional choice. Students must also calculate the arrival time when given the departure time and the elapsed time to determine if the team will be arriving in time. Additionally, students learn about an option to have a chance to win a drawing based on the cost of the transportation option selected.

In this MEA, students will have the opportunity to apply what they learned about describing
the changes water undergoes when it changes state through heating and cooling. This MEA
is divided into four parts. In part 1, students will develop their hypothesis and receive
information on how to set up the cooler experiment. In part 2, students will use ice to test
the coolers they designed in Beat the Heat Engineering Design Lessons. Students will take
measurements and collect data on their cooler. In part 3, students will analyze the data
they collected. Finally, in part 4 they will develop a procedure for selecting the most
