Balls rolling down a playground slide: What factors influence their motion?

Take a selection of balls and marbles along to a nearby playground slide and let students investigate factors that may influence how balls accelerate down an inclined plane. Students can make hypotheses in small groups, plan investigations to test multiple possible explanations and draw conclusions about the importance of different variables. The experiments illustrate the principle of equivalence between inertial and gravitational mass, as well as of the importance of mass distribution. Students can develop an intuitive feeling for these concepts even without dealing with the full mathematical treatment, which involves torque, angular momentum and moment of inertia, typically treated in high-school or introductory university physics courses. The paper discusses this investigation as part of a setup of teacher professional development events on a playground.

We Don’t Eat Our Classmates by R. Higgins

Higgins, Ryan T. We Don’t Eat Our Classmates. Disney-Hyperion, 2018
 This is a messy book. Ryan Higgins' drawings are much messier and less precise than his earlier books about Bruce, the bear. However, when you are Pamela Rex, a Tyrannosaurus rex starting school with a room full of delicious human classmates, things get messy, particularly when you have to spit them out.
 Ryan Higgins taps the absurd in both his images and text to keep children laughing. Penelope still wants to eat the children, even though her father “packed her a lunch of three hundred tuna sandwiches." There is also an image of Penelope trying to “make friends at recess,” but she is standing at the bottom of the playground slide with her mouth open. Penelope does eventually learn a small lesson in empathy when Walter, the class goldfish, bites her. 
 Higgins draws Penelope as a stuffed toy Tyrannosaurus rex, perhaps to prevent children from being frightened. The children are represented by the usual politically correct collection of stereotypes, often identified by clothing. There is one Jewish (yarmulke), one Muslim (hijab), two black (tight curly hair), one Indigenous (braids), one Japanese (the only child with a shirt and tie), and several generic “brown” children. All of the children have dark hair. Blue-eyed blonds are conspicuous by their absence. 
 In addition to being a fun book, this volume allows every child to claim the moral high ground. Every child can say, “I wouldn’t ever do that!”, because all children know that “we don’t eat our classmates.”
 While this is a book about being different, clashes of values, and learning to get along, it is mainly a book that will amuse children. Recommended for elementary school and public libraries.

Vertical patellar dislocation: A pediatric case report and review of the literature.

Vertical patellar dislocations (VPDs) are a rare event, and even more so among pediatric female patients. There have been less than 30 vertical patellar dislocations reported in the literature since the first in 1844. In this type of dislocation, the patella rotates about its vertical axis with the articular surface facing either medially or laterally. The mechanism of injury for a VPD can be broadly divided into two themes: a twisting injury or direct impact to the medial or lateral edge of the patella. We present a 10-year-old girl with a VPD after experiencing a twisting injury when descending a playground slide. The purpose of this study is to present a case report and review of the literature on vertical patella dislocations, including mechanisms of injury and suggested methods of treatment. We aim to provide a comprehensive understanding of the various categories of patella dislocations to alleviate confusion when classifying patellar dislocations. Furthermore, we provide clear suggestions for reduction methods and techniques with regards to vertical patellar dislocations, including a suggested protocol for an irreducible patella.

A Rareposition in Partial Hanging - A Case Report

In hanging suspension of body may be complete or partial. Different positions of partial hanging are noted in the forensic literature.Here we report a case of 15 year old school going boy who committed suicideby hanging in an unusual way by schooluniform neck-tie as ligature material on the play ground slide. The victim was in lying down position with his whole posterior aspect resting on surface along with head on the play slide. Medico-legal autopsy was done in department of forensic medicineatShriVasantraoNaik Government Medical College, Yavatmal to confirm the cause, mode and manner of death.Medico-legal, legal and social issues related to this rare type of unusual partial hanging case arediscussed. Key worlds: unusual, partial hanging, playground slide, necktie.

Applying Motor-Control Theory to Physical Therapy Practice: A Case Report

This case report describes the application of an integrated, systems-based theory of motor control to physical therapy practice.Client Description: The patient was a 5-year-old boy with spastic hemiplegic cerebral palsy who was entering kindergarten. Parent concerns related to the child's safety in playground activities such as playing on the slide. Motor-control theory, including factors related to the task, the environment, and the individual, was used to guide and direct physical therapy management related to the patient goal of safely and effectively climbing the ladder to the playground slide.Patient Outcomes: When the child entered kindergarten, he was able to safely ascend the ladder to the playground slide, using a modified movement pattern, when distractions were minimized. However, attentional issues continued to affect task execution when other children were present. This case report demonstrates a means by which current knowledge and theory can be integrated into clinical practice. Applying motor-control theory to this case led to the development of clinical questions for future research.

Tibia Fractures in Children Sustained on a Playground Slide

The purpose of this study is to investigate the relationship between children who sustain tibia fractures on a playground slide and the mechanism of injury. This retrospective review included the chart and radiographs of all children diagnosed with a tibia fracture, over an 11-month period. All patients were originally seen in either the emergency room of a level 1 trauma center or the treating physician's office. During the period of study, 58 fractures of the tibia were found. Eight (13.8%) of the tibia fractures were sustained while playing on a playground slide. The 8 fractures identified are the focus of this study. The tibia fractures were nondisplaced, diaphyseal, with an intact fibula. There were 5 female and 6 male children included in the study. The age range of the patients with a tibia fracture sustained while going down a slide was 14 months to 32 months; the average age of the 8 children in this study was 20.6 months. The average age of boys sustaining a tibia fracture on a playground slide was found to be 20.7 months and the average age of girls was found to be 20.6 months. All tibia fractures associated with playing on a slide were sustained while going down the slide on the lap of an adult. None of the 8 children studied went down the slide alone. Children at risk for tibia fractures sustained while going down a playground slide, on the lap of an adult, were found to be less than 32 months of age. Many parents believe they are increasing the safety of their young child by placing the child on their lap while going down a playground slide. Parents should be educated not to go down a slide with a child on their lap. If the child is unable to use the slide independently, another activity would be more appropriate. Therapeutic study, level IV.

Chiropractic care of a 6-year–old girl with neck pain; headaches; hand, leg, and foot pain; and other nonmusculoskeletal symptoms

Objective The purpose of this case report is to describe the response to chiropractic care of a pediatric patient with complaints of neck pain; headaches; and hand, leg, and foot pain after head trauma and the reports of changes in the patient's history of chronic fatigue, vomiting, and coughing. Clinical Features A 6-year–old girl was pushed into a playground slide, hitting her head and resulting in acute complaints of her “neck and brain hurting” and hand, foot, and occasional leg pain. In addition, the patient had a several-year history of unexplained fatigue, vomiting, and coughing spells. She had a neck pain disability index of 17.8%; left lateral and rotational head tilt; cervical antalgic lean; loss of cervical range of motion; anterior cervical translation; and spasm, tenderness, trigger points, and edema along the cervical and thoracic spine. Intervention and Outcome The patient was cared for using Activator Methods protocol. After the fifth treatment, all the patient's symptoms dissipated, with a complete return to normal activity and spinal stability after 9 treatments. At 19 weeks, her spine continued to be asymptomatic; and her neck disability index was 0%. Conclusion This case demonstrated that the Activator Method of chiropractic care had a beneficial effect for this pediatric patient.

年齢別子ども転倒シミュレータによる遊具の転倒傷害危険度の可視化

In order to clarify and understand hazards lurking in playground equipment, visualization of the hazard is effective way. Therefore, we developed a method to construct hazard maps of playground equipment, calculated from simulations, by using computer models of children falling on a playground slide. This method makes it possible to understand the hazards of playground equipment easily. Full-body multi-body models of children, based on Japanese data, were constructed. The hazard map of a playground slide was constructed to provide an example of possible hazard maps of playground equipment. Simulations of children falling on the playground slide were carried out by using both the multi-body models for children and the playground slide models, which were constructed from CAD data of an actual slide. The calculated head injury hazard values were mapped on the playground slide model so as to easily identify hazards. As the results, the maps made it possible to understand easily that the hazard varies greatly due to initial falling position on the spiral staircase and also children ages.

B19 子供マルチボディモデルの構築と遊環境の危険度可視化法に関する研究(筋骨格系のバイオメカニクス2)

The purpose of this study is to construct a method for visualizing dangers lurking in environments where children play. For this purpose, a risk map was created by using the simulation. For the simulation, a child multi-body model was created by using the anthropometry data, and existing body segment parameters for children were used. A parameter study was performed, and the influence of the inertial properties and the anthropometric dimensions on the behavior of falling was examined. Finally, taking the fall from a circular staircase attached to a playground slide as an example, falling accidents were simulated using the created model, and a risk map was constructed. As a result, unpredictable dangers lurking in the play environment could be visualized.

For Want of Wind

Le Théâtre Petit Cercle playfully engages the infamous southeasterly winds in this collaborative design-build project moored to a playground slide. Students from Dalhousie University School of Architecture and Planning and the community of Chéticamp, Nova Scotia, combined efforts to make architecture that builds on community spirit and a sense of place.

Elbow dislocation with ipsilateral open radial and ulnar diaphyseal fractures — a rare combination

An 8-year-old Caucasian male was referred to our unit with a left upper limb injury sustained during a fall from a playground slide. The exact mechanism of injury is unknown but it was reported that the patient’s full body weight was transmitted through the left arm on impact. Examination revealed a markedly swollen left elbow and left forearm deformity with two 1cm lacerations on the volar aspect of the forearm approximately 4cm from the wrist joint. Neurovascular examination was normal and there were no other injuries noted. Radiographic examination revealed a posterior dislocation of the left elbow associated with grossly displaced distal third fractures of the radius and ulna (Fig. 1). Elbow reduction and wound toilet were performed under sedation in the emergency room. A stable arc of motion was elicited at the elbow post reduction. Intravenous antibiotics (cefotaxime 750mg) and tetanus toxoid were administered.

Angelprincess and suicide on the playground slide. The culture of play and societal change

SUMMARY The foremost aim of this research is to discover how time and culture are reflected in children's play culture. The study's contextual framework has been based upon the changing roles of childhood and adulthood. Play culture is dealt with as viewed from the perspective of 23 six-year-old children (of middle-class backgrounds), who have grown up in Helsinki. The primary material consists of interviews and observations carried out both in homes and in day care centres. The results show that the dependency of play on time and culture may be traced from the microlevel of children's play culture to the macrolevel of profound changes and, in particular, the changing roles of children and adults. The change may be described with two metaphors. ‘Out of the garden’ stands for open competition and the adultomorphic tendencies of today, whereas ‘a little piece of land’ expresses children's unique persistence in creating their own play culture.
