In Shaunta Grimes' middle-grade novel Center of Gravity, a girl loses her mom, and her dad remarries quickly, so she must rebuild her life and friendships. Tessa is an anxious person, but it's become worse since her mother died a few months ago. To calm herself down she cuts out photos of missing kids—from milk cartons—and keeps them in a file. It helps her feel like she's not alone. When her dad announces suddenly that he's getting married—and that they're moving, Tessa must navigate new friendships and a new stepmother. She knows she should let go of old habits, but that's easier said than done. Her struggle is one that many readers will understand.

There have been numerous instances in which small children have been thrown out over the top of the seat belt in rough air and airline crashes, indicating that the present seat belt is not a satisfactory restraint device for children 2 to 10 years old. Data defining the location of the center of gravity of children of different ages in the sitting position have not been available and are urgently needed to serve as a basis for developing an improved restraint system for children. To supply these data for design requirements approximately 1,200 children (ages 5 to 18) were balanced on a specially designed center-of- gravity machine in sitting and standing positions. The center of gravity of small children in the standing position will be most useful in the design of flotation equipment. This study shows that the center of gravity for small children sitting in an airline seat is located roughly 5 in. above the seat belt and explains why children slip out over the seat belt during crash decelerations. Complete data of location of centers of gravity along with anthropometric data of the children studied are presented.
