Presents the history and explains the basics of hydroponics. Discusses the two categories of hydroponic systems, water-culture systems and media-based systems. (YDS)

Few people are more curious about their worlds than young children. Why, then, do so many science lessons begin with questions supplied by adults rather than kids? In many published programs, lessons revolve around set questions, with step-by-step directions provided for children to follow. This approach seems to say that young children are not…

The study described is part of a larger research programme designed to investigate primary aged children's learning during a visit to the Eden Project. Children from eight primary schools were interviewed approximately four weeks after a one-day, teacher-led visit to the Eden Project (EP) in Cornwall. Their responses revealed that the children…

This report provides results of Phase I of a project that researched the occupational area of environmental horticulture, established appropriate committees, and conducted task verification. These results are intended to guide development of a program designed to address the needs of the horticulture field. Section 1 contains general information:…

The exciting world of plants may be something of a mystery to many children, and the often-dry content of a curriculum taught indoors inhibits real understanding of many complex biological processes. Moving outdoors opens up an unexplored world and presents rich opportunities for imaginative learning. The "Life processes and living…

Research was carried out on the ethnobotanical potentials of common herbs in Nigeria using Enugu State as a case study. A total of 200 questionnaires were administered on herb sellers in major herb markets in the state. In all, 96 different plant species were encountered in the markets. Attempts were made to write the names of the species both in…
