Cavallo, Ann – Science and Children, 2005
Children notice seeds and plants every day. But do they really understand what seeds are and how they are related to plants? Have they ever observed what is inside the seed? What happens to the "things" inside a seed when it grows? What do plants need to grow, and what do they need to stay healthy? Through a sequence of three related learning…

Quinones, Christin; Jeanpierre, Bobby – Science and Children, 2005
Just asking questions can lead to the best classroom experiences. After a three-week unit on living things, one of the authors asked their second-grade students what else they wanted to learn about plants. Their questions were the prelude to a three-week inquiry on plant growth. From question formulation to presentation of results, the students…

Ugwu, Okechukwu; Soyibo, Kola – Research in Science and Technological Education, 2004
The first objective of this study was to investigate if the experimental students' post-test knowledge of nutrition and plant reproduction would be improved more significantly than that of their control group counterparts based on their treatment, attitudes to science, self-esteem, gender and socio-economic background. Treatment involved teaching…

Allen, Ashley J.; Balschweid, Mark; Hammond, Paul; Henderson, Brian; Johnson, Peggy A.; Kite, Abigayle; Martin, Stephanie – Science Activities: Classroom Projects and Curriculum Ideas, 2004
In this investigation, pairs of upper elementary students test germination percentage using seeds of Indian corn ("Zea mays"), scarlet runner beans ("Phaseolus coccineus"), and the prairie cup-plant ("Silphium perfoliatum") grown on rolled, damp paper towels. The pairs compare seeds that have been stratified, a simulation of overwintering and…

Opfer, John E.; Siegler, Robert S. – Cognitive Psychology, 2004
Many preschoolers know that plants and animals share basic biological properties, but this knowledge does not usually lead them to conclude that plants, like animals, are living things. To resolve this seeming paradox, we hypothesized that preschoolers largely base their judgments of life status on a biological property, capacity for teleological…

Flory, S. Luke; Ingram, Ella L.; Heidinger, Britt J.; Tintjer, Tammy – American Biology Teacher, 2005
Laboratory components of introductory biology college-level courses are becoming increasingly rare. Due to the absence of laboratory funding and time, instructors at all levels are faced with the problem of implementing inquiry-based projects. In this article, the authors present an activity that they developed for the 50-minute discussion period…

Sandro, Luke H.; Lee, Richard E., Jr. – American Biology Teacher, 2006
This article describes a variety of opportunities for educational activities that can be found in the complex, yet easy-to-manipulate, trophic relationships between goldenrod plants, insects that induce gall formation, and the natural enemies of these gallmakers. Gall collection, measurement, and observation (exit holes, larval response,…

Krantz, Patrick D.; Barrow, Lloyd H. – American Biology Teacher, 2006
The "National Science Education Standards" provide a vision and standard of science instruction that includes not only the factual, content-rich history of science but also an understanding of the processes and skills necessary to "do" science. Moreover, the "Standards" provide the framework for science instruction that embodies the use of…
