Presents ways to use ChiaPets to link biology-related topics such as taxonomy, morphology, ethnobotany, economic botany, hydroponics, salinity, photomorphogenesis, and phototropism with food and fertilizer chemistry, mathematics, art, and history. (MKR)

Presents laboratory activities focusing on the development of sexually mature gametophytes from single-celled spores. Includes techniques for culture and manipulation of gametophyte development from spores that are applicable for hands-on activities for students at all levels. (MKR)

Gardening helps children learn how plants sprout, grow, bloom, and then wither away, leaving seeds behind. Participating in this natural process allows children to experience the stages of life. Suggested gardening activities include studying dandelions, focusing on culture for garden plant selection, and constructing a worm box or worm terrarium…

Biological productivity is higher in coastal zones than for the rest of the planet. Discusses issues related to the patterns of human settlement and development of these areas. (MDH)

Students conducted an experiment to study the plant growth of three Amaryllis plants. Students examined the speed and amount of growth, cross-pollinated the plants to produce seeds, and compared the growth of amaryllis seeds to the growth of onion seeds, a plant in the same family, Amaryllidaceae. (MDH)

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)

Uses members of the Cruciferae family such as radishes (Sp. Raphanus), to describe a process termed allelopathy by which a plant uses a chemical compound that escapes into the environment to harm another plant. Tips are provided for easy use in the classroom. (ZWH)

Describes the classification, number, and origin of wildflowers in North America. Discusses the use of a poster attached to the journal that includes activities to help students develop an awareness and appreciation of the native flora of North America. Additional activities are referred to in a list of 20 additional resources. (MDH)

A naturalist and designer of public gardens relates her experiences of introducing children to plants and gardens using equipment such as binoculars, stethoscopes, notebooks, photographs, and magnifying glasses. Article provides information is given about many plants, their uses, and related child-centered activities (such as a namesake pumpkins…

Explores the ecosystem in Pacific Northwest Coastal America and investigates land management issues. Discusses the impact of canopy trees on temperature and the forest itself. Explains fungi's relationship with trees and presents activities on stream flow, wood, volcanoes, and plants for the classroom. (YDS)

Technological communities used bibliometric data on 411 plant biotechnology organizations to study the effect of field density and structure of the research and development network. Findings indicate the usefulness of bibliometric data in mapping change in technological communities and in the effects of networking on entry behavior. (PEN)

Shares an approach to tree identification that can be adapted to use with all levels from middle school through college. Stresses student involvement and cooperation in a botanical scavenger hunt. Describes the development of the treasure map and how to use the guide sheet. (DDR)

Argues that ongoing cooperation between teachers and maintenance personnel is required when planning and implementing schoolyard projects. Reviews planning, safety, and physical security considerations. (DDR)

Demonstrates how leaf slices provide an inexpensive material for illustrating several fundamental points about the biochemistry of photosynthesis and respiration. Presents experiments that illustrate the effects of photon flux density and herbicides and carbon dioxide concentration. (DDR)

This activity makes students a part of an investigation that determines the frequency of a particular plant variety in a simulated population. Provides an opportunity for students to observe the inherent variability of estimates, observe the relationship between sample size and sampling error, and consider aspects of research design.
