Presents a demonstration to show students how wind and temperature can influence the rate of transpiration in a plant. Lists supplies needed and steps for the procedure. (NB)

Presents an activity that addresses cultural differences and diversity through ethnobotany. Offers a multicultural framework designed to develop concepts about plant characteristics and taxonomy. (ASK)

Presents two exercises on the study of tropisms. Discusses gravitropism control mechanisms present in plants. (ASK)

Discusses how the many problems in botany teaching are interrelated and most have existed since at least the early 1900s. Considers botany teaching at both the precollege and introductory college levels. Discusses botany neglect in biology teaching, botanical illiteracy, uninteresting or irrelevant botany teaching, zoochauvinism, research…

Presents a soybean project designed with an interdisciplinary approach that includes the stages of planting soybeans, studying the impact of rhizobium bacteria on soybean root development, synthesizing the raw oil to methyl ester, testing of biodiesel on a hybrid electric car, and studying the commodities market. Integrates plant science,…

Presents three science activities targeted to help urban students learn about nature: (1) observing coloration patterns of pigeons; (2) measuring local rainfall and comparing it to other areas; and (3) conducting a biodiversity study by observing a patch of lawn. (YDS)

Presents an experiment using plants grown on the classroom window sill that allows students to gain valuable hands-on experience in the collection and analysis of empirical data. (ASK)

Discusses Knob's solution, which was considered the ideal plant growth solution in 1865, and recommends eliminating Knob's solution from active teaching. Describes solution culture basics including nutrient solutions, containers and aeration, and plants and light. (Contains 12 references.) (YDS)

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…

To date, little of the ecological research on biological diversity and ecosystem functioning has been carried out in agricultural systems, despite the fact that agriculture is a major contributor to loss of native habitats and species. However, agricultural research has demonstrated that polycultures of multiple crop species can have higher total…

The grade three curriculum set out by the British Columbia Ministry of Education has four categories for science: Processes of Science, Life Science, Physical Science, and Earth and Space Science. Within each of these categories there are numerous topics to teach. For example, the physical science curriculum requires students to learn about…

Children and teachers may not think in the same way about particular science concepts. Such parallel lines of thought can compound children's confusion and misunderstanding as they learn science at primary school. The situation could be more acute when student teachers are teaching science, because of their limited experience of considering…

This study investigated the contributions of students' reasoning ability and meaningful learning orientation to their understanding of the photosynthesis and respiration in plants concepts. Data were gathered through the use of the Test of Logical Thinking (Tobin & Capie, 1981), the Learning Approach Questionnaire (Cavallo, 1996), and the Two-Tier…
