School backpacks must weigh maximum of 10 or 15% body weight holder, and never exceeded to prevent health problems, such as back pain and spine arched, According to experts. El alumnado puede calcular el peso que puede soportar en clase de Matemáticas y exponer los resultados gráficamente con ‘DIY Chart Builder’.
How to properly load the pack? How lifting the ground without a hitch? How to sit at the computer? These and many other questions are answered in the ergonomics, the body of scientific knowledge applied to work, systems, products and environments to suit the abilities and physical and mental limitations of the person. This scientific discipline seeks to design the service of the physiological characteristics, User anatomical and physiological. After learning more about their domains, benefits and areas, You can ask students, divided into groups of 3-4 people, to choose an ergonomic design for average and analyze it in depth, and then present it to other colleagues.
The back is an area of the human body that may be particularly affected by the excessive load and / or inadequate weight. With the help of teachers, You can ask learners to draw a diagram showing the back where the main injuries can suffer back due to overload.
To avoid back pain and bowing of the spine, must take into account the weight of the backpack in relation to body weight. This is one of the tips to bear weight properly and also use backpacks with wide, padded straps distribute the weight or, for example. It may suggest to students that Internet report on other boards of this nature may be beneficial. Then they can make a sharing in establishing a set of guidelines and present in poster format so as to involve the rest of the school community.
It would be interesting to consider a series of mathematical problems related to the news. You could start working the percentages by asking students to calculate the maximum recommended weight of their backpacks for each, considering that lead experts recommend a maximum weight equivalent to 10 or 15% body weight of the carrier who. Once the data have, may be advised to carry out a problem involving addition and subtraction, weighing the books and other school materials to know how many can lead. Finally, may be advised that all results are presented in the form of statistical tables.
This can be used ‘DIY Chart Builder’, a tool online Simple and powerful tool for creating interactive graphics, and graphs from static or dynamic data that can be generated using any language scripting. After creating an account and you can create a graph and then publish. This application stands out for its ease of use as the variety of available plots (columns, bars, pyramid, cake, etc.). For more information, You can watch this video.
Parallel, can carry out a brainstorming on the concept of ergonomics relating it to the benefits that may seek to education. The activity would be that students propose ideas to change the design of both their place of study and the tools used for this purpose with the intention of improving their learning environment. Proposals must be evaluated and weighted by the whole class, arguing, above all, feasibility and appropriateness. This work can be carried out on line platforms such as real-time chat designed for groups ‘Campfire’.
