"As Kristin Berbawy packed projects into her car, she lingered over one in particular. Two 3D-printed Makerbots with wire hooks-a pair of earrings. They matched the white braces on her teeth and the white strands in her hair. Her students had made them-as they had all the projects in her car-in their high school makerspace. She was proud of them. She was going to display their work to other teachers. Smack in the middle of AP exams, a growing group of teachers is pouring time, creativity and energy into activities for which there are no standardized tests: makerspaces. The movement is avowedly grassroots and candidly quirky, and its main gathering is the Maker Educator Convening in Oakland, CA, where Kristin Berbawy was headed with a trunkload of laser cut wood and 3D printed objects.

"Yik Yak is an app that allows anyone to post anything without attaching themselves to a username (you don't even need a password to log in). The timeline of Yik Yak looks like Twitter or Reddit without photos or handles: Yik Yak Yik Yak It's extremely localized; anyone within 1.5 miles of a message can read it. The fact that the network is built on physical proximity is key: If you open Yik Yak in the middle of Times Square, it's unlikely that the app will be of any benefit to you. If you open it in the middle of a high-school cafeteria, brace yourself."

"Bones are rigid organs that form part of the endoskeleton of vertebrates. They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue is a type of dense connective tissue. Because bones come in a variety of shapes and have a complex internal and external structure they are lightweight, yet strong and hard, in addition to fulfilling their many other functions. One of the types of tissue that makes up bone is the mineralized osseous tissue, also called bone tissue,that gives it rigidity and a honeycomb-like, three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum and periosteum, nerves, blood vessels and cartilage. There are 206 bones in the adult human body and 270 in an infant."

"You saw the pictures in science class-a profile view of the human brain, sectioned by function. The piece at the very front, right behind where a forehead would be if the brain were actually in someone's head, is the pre-frontal cortex. It handles problem-solving, goal-setting, and task execution. And it works with the limbic system, which is connected and sits closer to the center of the brain. The limbic system processes emotions and triggers emotional responses, in part because of its storage of long-term memory. When a person lives in poverty, a growing body of research suggests the limbic system is constantly sending fear and stress messages to the prefrontal cortex, which overloads its ability to solve problems, set goals, and complete tasks in the most efficient ways. This happens to everyone at some point, regardless of social class. The overload can be prompted by any number of things, including an overly stressful day at work or a family emergency. People in poverty, however, have the added burden of ever-present stress. They are constantly struggling to make ends meet and often bracing themselves against class bias that adds extra strain or even trauma to their daily lives."
