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.

Students will read an engaging reading passage about what the skeletal system does and has a little activity called "Jumbled Bones" that has the students make a small human skeleton for their notebooks. Students will then explore, in small groups, chicken bones with magnifying glasses. The students will look at the bones for evidence of structure and components and they will speculate about purpose the bone served based on its physical appearance. Next, they will watch a short video clip about how red blood cells are produced. The teacher will follow-up with a class discussion about "How the skeletal, respiratory and circulatory systems work together to maintain homeostasis" and students will write a summary explanation in their interactive notebooks. For further elaboration, students will watch a video clip "Bones Narrated" which is a guided tour of the skeleton and its functions, and do a virtual game called "Build a Skeleton" which allows students to drag bones to create a human skeleton. Lastly, students will be evaluated on their knowledge of the skeletal system and its functions by creating a poster to present and explain to the teacher.

The article highlights the work of cell biologist, Yoshinori Ohsumi, who won the Nobel Prize for physiology for his research on how cells recycle unused materials in order to maintain homeostasis. Ohsumi studied what the cell did if it started to "starve." He noticed how the cell would start "eating" some of the parts it didn't really need in order to survive. This process is called autophagy. Scientists hope that Ohsumi’s discovery will help find a cure for diseases like Alzheimer's, which is caused by cell trash buildup in the brain.

Scientists who are working to discover new medicines often use robots to prepare samples of cells, allowing them to test chemicals to identify those that might be used to treat diseases. Students will meet a scientist who works to identify new medicines. She created free software that "looks" at images of cells and determines which images show cells that have responded to the potential medicines. Students will learn about how this technology is currently enabling research to identify new antibiotics to treat tuberculosis. Students will complete hands-on activities that demonstrate how new medicines can be discovered using robots and computer software, starring the student as "the computer." In the process, the students learn about experimental design, including positive and negative controls. Students should have some introductory knowledge about the following topics: (1) biology: students should have a basic understanding of infection and good hygiene, they should know what bacteria and cells are; (2) chemistry: the students should know what a chemical compound (molecule) is. They should have an understanding that medicines, also called "drugs", are chemical compounds; (3) basic experimental design: students should understand the terms "samples" and "testing".
