Discusses an art activity for fifth-grade students that focuses on the teaching technique called scratchboard. Explains that the subject of the assignment was sunflowers. States that sunflowers make good subject matter for children since the shape is geometric. Addresses how to create the scratchboard sunflowers. (CMK)

Background information on the methods and varieties used to demonstrate the cultivation of plants without the use of chemical pesticides is provided. Discussed are species and variety selection, growing plants from seed and from seedlings, soil preparation, using cuttings, useful crops, and pest control. (CW)

Directions for the construction of a model bog habitat are provided including examples of plants and animals which may be suitable. Activities that use this model are suggested. Background information on the ecology and chemistry of the bog is included. (CW)

Describes a computer model characterizing the balance of soil-plant Nitrogen that allows students to see the likely consequences of different biological and weather-related parameters. Proposes three uses for the model: (1) orienting beginning students to understand the soil Nitrogen cycle; (2) providing information for advanced students; and (3)…

Investigates the use of temperature and light to change the usual intervals for plant germinating, sprouting, and flowering. Provides simple experimental procedures and discussions regarding photoperiodism, forced branching before spring, and various types of seed dormancy, including physical dormancy, physiological dormancy, and double dormancy.…

Presents a cooperative activity between home and school in which parents and students examine the growth of a variety of bulbs. Bulbs are taken home to sprout and returned to school to monitor their growth. Students gather data, hone observation and graphing skills, and communicate with their parents on the project. (MDH)

Investigates the attitudes and values that children and adolescents hold with respect to nature and the patterns of reasoning with which they are expressed. Outlines current positions in environmental ethics, discusses difficulties in applying contemporary theories of moral development to the problem, and summarizes preliminary results of the…

In this article, the author presents a two-week evolution unit for his biology class. He uses Maria Sybilla Merian (1647-1717) as an example of an Enlightenment mind at work--in this case a woman recognized as one of the great artists and natural scientists of her time. Her representations of butterflies, caterpillars and their pupae, and the…

This research paper focuses on "teacher-led" primary school visits to the Eden Project in Cornwall, England. It considers the objectives of school visits and the aims of the Eden Project. The strategies used by the Eden Project to convey their messages are investigated and effective strategies for learning are evaluated, based on…

Through an interactive partnership, fifth-grade students collected data on plants and joined an active scientific community of working scientists. This Web-based Integrated Science Environment (WISE) project involved asking questions about plants, growing plants in the classroom, and discussing their data with scientists online. (Contains 5…

The World Wide Web and other computer-based media are new teaching resources for plant identification. The purpose of the experiments reported here was to test whether learning plant identification for woody and herbaceous plant material over the web was as effective, more effective, or preferred by undergraduate students when compared with…

The ability to utilize and change energy is one of the most fundamental characteristics of living things. Plants have the unique ability to change light energy into the chemical energy on which human beings depend for such things as fuel and food. Through the activities in this book students examine how plants and other living things use and…

This book presents a collection of motivating, independent activities that involve animals and plants for use in developing the research skills of students in grades 2-6. Projects included in the book cover various levels of difficulty and are designed to promote higher-level thinking skills. Research components included in the activities in the…

The Space Exposed Experiment Developed for Students (SEEDS) Project offered science classes at the 5-12 and college levels the opportunity to conduct experiments involving tomato seeds that had been space-exposed over long periods of time. SEEDS kits were complete packages obtained from the National Aeronautics and Space Administration (NASA) for…

This five day unit, designed specifically for the third grade level, integrates the social and natural sciences. The unit introduces students to how plants were used in the past, and how they are used today. It also incorporates critical thinking skills that will encourage students to explore how plants will play a role in our future. The first…
