Describes an activity that reduces the biosphere to a water-filled jar to simulate the relationship between cellular respiration, photosynthesis, and energy. Allows students in high school biology and related courses to explore quantitatively cellular respiration and photosynthesis in almost any laboratory setting. (ASK)

Presents an integrated lesson on planning a garden and planting seeds with a focus on number concepts and Fibonacci numbers. (ASK)

Provides a chart comparing state and national objectives. Assesses student understanding of photosynthesis and explains the process of teaching students producer-consumer relationships. (Contains 14 references.) (YDS)

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)

Suggests activities to elicit and develop children's conceptual understanding of plants. (Author)

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)

Summarizes the recent research on pollen germination and introduces some basic studies on pollen tube growth that can be conducted in a secondary school laboratory. Discusses the use of a light microscope and refrigerator to study pollen. (Contains 13 references.) (Author/YDS)

Presents a science activity focusing on student ideas about plants and builds a terrarium based on students' ideas about the conditions of plant growth and cycling. (YDS)

In the fall of 2002, teachers at the author's school were expressing interest in finding new ways to teach science as inquiry--and she was looking for an interesting plant inquiry for second-grade students. That November, She attended a Journey North workshop at the Tennessee Science Teachers Association convention and had an "a-ha"…

According to the National Science Education Standards (National Research Council 1996), students in the middle school years should progress in studying life science from examining individual organisms to recognizing patterns in ecosystems and developing an understanding about the cellular dimensions of living systems. Students should broaden the…

The use of plants for healing purposes has been prevalent in all cultures throughout history and continues to play a role in medicine today. While herbal medicine has much to offer, adverse effects can result from lack of quality control and standardization, consuming an inadequate dose, using the wrong herb, and reactions with modern drugs. To…

How is the university connected to the pressing social and environmental problems that confront citizens in its region? What sorts of communities will students build in this changing cultural and environmental landscape as a result of their experiences in education? In this article I explore how an ethnobotany seminar uses critical pedagogy of…

The seashore is many things: (1) a place of wonder and delight--inspiring artists and composers; (2) a place of work--for transport and fishing; and (3) a place for play--for sandcastles, surfing and swimming, sailing. In this article, the authors offer some tips on exploring the flora and fauna of the seashore. (Contains 3 boxes and lists 4…

This design study tracks the development of student thinking about natural variation as late elementary grade students learned about distribution in the context of modeling plant growth at the population level. The data-modeling approach assisted children in coordinating their understanding of particular cases with an evolving notion of data as an…

For many children across the globe, whether in low or high income nations, growing up in the 21st century will mean living in overcrowded, unsafe and polluted environments which provide limited opportunity for natural play and environmental learning. Yet Agenda 21, the Habitat Agenda and the United Nations Convention on the Rights of the Child…
