Elementary Practical Physiology

This elementary work on Physiology is intended to present the more important facts and principles of Physiology in a concise and intelligible form to junior students. The book is divided into twenty chapters. The general anatomy and structures of the body and its organs are described as far as this is necessary to the proper understanding of their functions. There is also included some account ...

Standard 4—Science Elementary

This is evident, for example, when students: ▲ investigate the interactions of liquids and powders that result in chemical reactions (e.g., vinegar and baking soda) compared to interactions that do not (e.g., water and sugar). ▲ in order to demonstrate the transformation of chemical to electrical energy, construct electrical cells from objects, such as lemons or potatoes, using pennies and alum...

Practical simplification of elementary functions using CAD

Simplification has been long recognised to be a fundamental problem within computer algebra. One of the main concerns of this paper is to investigate the feasibility of the simplification system proposed by the authors in ISSAC 2004. This will be based on a set of examples which one would might realistically meet in practice. Cylindrical Algebraic Decomposition (CAD) is an integral part of this...

Group Work in Elementary Science 1 Group Work in Elementary Science: Organisational Principles for Classroom Teaching

Group work has been promoted in many countries as a key component of elementary science. However, little guidance is given as to how group work should be organised, and because previous research has seldom been conducted in authentic classrooms, its message is merely indicative. A study is reported, which attempts to address these limitations. Twenty-four classes of ten-to twelve-year-old pupil...
