Children and Water [1014KB]
Jos Elstgeest
This is a chapter from the UNESCO Source Book of Science in the Primary School, Within this chapter are various activities comprising a certain sequence of experiences which are related to a particular aspect of the science of water. This chapter also brings out another important aspect of scientific activity: the recognition, use and control of variables. This ability is rather difficult to “teach”, as it requires some insight and hindsight into one’s own investigative work, which makes critical appraisal possible.

Children, Mirrors & Reflection [553KB]
Jos Elstgeest
This is a chapter from the UNESCO Source Book of Science in the Primary School. Mirrors are fascinating things to play with as well as to work with, for they hold an element of magic. Magic and science seem to be at odds, but not necessarily to children. The activities in this chapter need little introduction to the children: just by providing them with mirrors, and slowly structuring and ordering their investigation, children will extract vast amounts of information from mirrors. It is a unit of learning which entirely depends on children handling mirrors and other things they need.

K. A. Subramanian
Published under the “Project Lifescape”, an initiative of the Indian Academy of Sciences aimed at enhancing the quality of science education, this field guide seeks to familiarise students and teachers with Dragonflies and damselflies, which are collectively called odonates. With extensive information on distribution, ecology and behaviour, this publication would be of great use in designing field exercises and projects focusing on first-hand observation of these insects.
