Conrad Hal Waddington's epigenetic landscape is now a central paradigm in evolutionary developmental biology. This article proposes that it should be adopted into middle-years (ages 11-16) biology curricula as a way of visualising the interactions of the genome with the environment. The epigenetic landscape is explained, with some biographical…

This article reviews the practical plant biology workshops presented by Science and Plants for Schools (SAPS) at the Association for Science Education Annual Conference 2017. The well-received workshops enabled attendees to try out SAPS practical investigations, with the support of experienced "experts" and colleagues. The resources…

The prevalence of nine indicator lichens found on trees in Northern Europe and Western Russia was used for monitoring air quality. The 4200 mile route of the survey went through eight countries. Surveys were carried out in cities, towns, countryside and forests, and along motorways. The author has conducted tree lichen surveys with pupils from…

This article looks at the potential of bioenergy as a replacement for fossil fuels, the cutting-edge research being undertaken by scientists, and classroom resources available for teaching this topic. There is currently a large programme of scientific research aiming to develop advanced biofuels (replenishable liquid biofuels from non-food plants,…

African violet (genus "Saintpaulia") was identified as a particularly suitable genus for the study of specialised plant cells in the classroom using microscopes. The techniques described here involve simple preparation without staining. The cells and structures that can be investigated include: trichomes (hairs); stomata; guard cells and…

Plant tissue culture is becoming an important technique for the mass propagation of plants. Problems with existing techniques, such as slow growth and contamination, have restricted the practical work in plant tissue culture carried out in schools. The new protocol using garlic meristematic stem discs explained in this article addresses many of…

Describes several games from various sources which can help in teaching about photosynthesis, pollution, pollination, plant parts, Earth history time-scale, biodiversity conservation, values, and communication. Requires little equipment and games are easy to organize and effective with various age groups ranging from primary to adult. (Author/YDS)

Presents a brief overview of allelopathy, or "chemical warfare" among plants. Includes suggestions for school science topics of study and activities. (Contains 11 references.) (Author/WRM)

Ways in which linear lesson sequences can be modified to provide increased opportunities for open-ended activities especially with problem solving are considered. Examples drawn from chemistry and plant reproduction, seeds, and germination are given. (KR)

A collection of creative pupil activities in science lessons is presented, discussed, and illustrated. The activities include drawing, acting, gaming, and modeling. The relative merits of work of the types described are analyzed. (KR)

Summarizes the benefits of using hydroponics in school for investigational work. Lists requirements and includes advice on suitable plant choices. Outlines the various growing systems and growing media and provides suggestions for science investigations using hydroponics. (DDR)
