The article discusses the distinguishing characteristics of the agricultural science. The branch of sciences have emerged as distinct entities from other branches such as biological sciences, mathematics, physics, chemistry, and the social sciences, during the past century. The continual development in agricultural sciences has served as a vehicle for exploring new areas and catalyzing an onrush of changing technology as new problems are encountered. The nature, achievement, and challenges of various discipline of agricultural science including soil, plant, animal and food sciences are explored.

The article reports on the development of a course of study in space science suitable for instruction in the ninth and tenth grades in the secondary school. The participants of the study were part of the top five percent of their class who were recommended by the principals of their schools. The method and research design involved the technique used in developing curricular materials and selection of the fundamental ideas of the physical sciences. The study focused on ideas in the fields of chemistry, physics, astronomy, and mathematics.

The article presents a study aimed to determine the frequency of mathematical processes utilized and included in the integrated physical science textbooks for secondary school. Physical science textbooks were surveyed to find out the mathematics included in each. The results of the study indicate the accuracy of the hypothesis that in integrated physical science course when mathematical concepts seem to give clearer understanding of text material, textbooks appear to be deficient.

The article discusses the role of mathematics in the physics classroom. By giving three situations to highlight the significance of mathematics, five ways are analyzed in which mathematics comes in the discussion on physics in the classroom. Sometimes mathematics shows relationships between different divisions of the subject, for example between kinetic energy and momentum. Mathematics also clarifies and enriches the understandings and concepts of physics. The concept of the hammer that descends on the nail, for example, cannot be clarified without calculations. The dimensions of the units in which physical quantities are measured can be clarified with the help of mathematics. The connection of mathematics with physics is visible in the direct and practical application of physics to practical situations. For example, when a gunner takes aim at the distant enemy, he is using mathematical tables worked out on the basis of physical laws.
