The proper physical development of a child is the last criterion for achieving educational maturity. It is often underestimated; however,it is very significant in school activities, since a healthy, physically fit, and properly nourished child will be less exhausted by sitting at a desk, walking to school, or performing various tasks which may often seem challenging. The purpose of the paper is to evaluate the school maturity of kindergarten age and early school age children and their somatic and motor development in the context of their commencing school education. While verifying these general rules, studies on a group of 628 girls and boys aged 6 and 7 years were conducted in the city of Opole. The test prepared for this survey consisted of 7 fitness tests and body height, weight, and fat measurements. The results obtained have been subjected to statistical analysis. An analysis of the morphological measurement results and fitness tests demonstrate that both the six-year-old girls and boys did not attain the same level of physical school maturity as their 7 year old schoolmates. This level of maturity would enable them to withstand the educational requirements of the primary school curriculum.

The aim of this paper was to determine the differences in the designed and manufactured model of a suspension. A set of key parameters was compared, including camber and toe in angles and their change w.r.t wheel travel, as well as the motion ratio. It also focused on the possibility of accurately determining the suspension system kinematics using affordable measuring devices available on the market. First, the design process, main goals and project assumptions were briefly described. Next, the CAD model and manufacturing process was presented. Finally, the measurements of both computer and real model were performed. The obtained results were compared and a significant difference between models was observed. The reason of such variation could not be determined unambiguously, as there were numerous factors that could potentially influence the results. Moreover, it was proven that accurate determination of kinematics is impossible using the given set of measuring devices.
