Primary school pupils in the UK today may be less familiar with natural objects, less exposed to formal natural history teaching and have less time given to school-based observation and discussion of natural objects. This study of children's responses to a "Nature Table" of displayed natural objects was designed to assess pupils' knowledge of those objects, the sources of their knowledge and the phenomenological nature of those children's interest in items which they selected to talk about or to photograph. Children in the study were drawn from the first year of formal schooling (age 5-6) and the fifth year of formal schooling (age 9-10). Responses have been recorded and analysed using a simple systemic network. Results show that pupils are attracted most towards items with: an animate or novel nature or appearance, or for which they have some prior familiarity. Items are also attractive if they have aesthetic attributes, which display some responsiveness to the child or engage with the child's previous experience, or elicit affective feeling. The present study reveals a greater home-based, rather than school-based, source for much of this experience and suggests how the criteria for teachers selecting natural objects for learning in school might be improved.

Rapid-cycling brassicas can be used in the classroom to teach concepts such as plant growth, tropisms, floral reproduction, pollination, embryonic development, and plant genetics. Directions on how to obtain them for classroom use and how they may be grown are included. Practical physiology and genetics exercises are listed. (KR)

Ornamental gourds are easily raised in school gardens and grow in a great variety of shapes, textures and colors. By observing and recording the biodiversity of gourds, students can learn about heredity and genetics, including Mendelian particulate inheritance and genetic plant-breeding. The experiment described can be used with students aged between 14 and 16.
