This article argues the need for, and provides, a dichotomous single access key for the identification of common British wild flower families. A minimum of technical vocabulary is used while at the same time retaining most of the recent botanical names of families. The key provides a user-friendly opportunity for school pupils to become familiar…

Students can use seed characteristics to discriminate between the different kinds of legumes using taxonomic classification processes of sorting and ranking, followed by construction of taxonomic keys. The application of the Learning Cycle process to taxonomic principles, hierarchical classification, and construction of keys presents the…

Thematic topics offer tremendous potential for science learning in the early grades and beyond. One second-grade class explored honeybees, a subject their teacher found both fascinating and easy to connect to a number of learning standards and science concepts. Her unit, "Honeybees and Apple Trees: A Close Look at Nature's Balancing Act," explored…

Most history books for children focus on people, places, and events. In a different approach, some authors focus on an object--an everyday item that might be ignored when it comes to writing history. They shine a spotlight on the item, and in the process, they add insight and interest to human history. This article looks at four outstanding books…

This program is the third in the Science Safari series produced by the Fairfax Network of the Fairfax County (Virginia) Public Schools. It focuses on animals and plants that are native to the continent of North America and highlights the importance of species interdependence. The aim of this program is to provide students with the knowledge…

Describes an education-government-community environmental partnership program that set aside permanent environmental study sites where students and teachers can conduct meaningful, service-oriented environmental research. Highlights a project where students prepared a comprehensive plant species inventory of a section of the wilderness area.…

Colors are powerful tools for engaging children, from the youngest years onward. We hang brightly patterned mobiles above their cribs and help them learn the names of colors as they begin to record their own ideas in pictures and words. Colors can also open the door to an invisible world of electromagnetism, even when children can barely imagine…

A modification of the popular C-Fern system, the tropical fern Ceratopteris richardii is developed in which students plate out a genetically mixed set of fern spores and then select for specific mutants. This exercise can provide students with an experience in plant mutant selection and can be used as a platform to expose students to a diverse…

Today's biology educators face the challenge of training their students in modern molecular biology techniques including genomics and bioinformatics. The Dolan DNA Learning Center (DNALC) of Cold Spring Harbor Laboratory has developed and disseminated a bench- and computer-based plant genomics curriculum for biology faculty. In 2007, a five-day…

At home, children often have pets that they take care of and play with; even in the classroom it is not uncommon to find a wormery, an aquarium or an ant farm. However, children rarely have the opportunity to own and care for a plant over a lengthy period of time, let alone a tree. The authors describe a project in Portugal aimed at improving…

Describes The Flora of North America, the first comprehensive description of all plants growing spontaneously in North America. Discusses online resources, the publication as an educational resource, the published volumes, and scientific and planning applications. (JRH)

Introduces a brine shrimp assay to demonstrate the effects of the biological activity of herbal remedies. Describes two protocols, one using aqueous extracts and the other using methanol extracts. (Contains 21 references.) (YDS)

The South Pacific Action Committee for Human Ecology and Environment (SPACHEE) involved women in experiential workshops to explore forest ecosystems. The first phase focused on the forest environment, the second on documenting and promoting traditional medicine and medicinal plants, valuable local knowledge that can persuade people to protect the…

Describes a method to collect seeds that are dispersed from weeds while avoiding some outdoor hazards such as rough terrain or animals. Describes a plan for creating a weed fishing pole and includes a materials list. (SAH)

Both indoor and outdoor garden plants can cause problems. For example, the foliage of the bird-of-paradise and philodendron plants is toxic. A poinsettia leaf can kill a young child. Outdoor plants such as castor beans are highly dangerous. All parts of the potato and tomato plant are poisonous, except the potato and tomato themselves. Large…
