Citizen science is a rapidly growing emerging field in science and it is gaining importance in education. Therefore, this study was conducted to document the pedagogical content knowledge (PCK) of biology teachers who participated in a citizen science project involving observation of wild bees and identification of butterflies. In this paper,…

Sixth-grade pupils at St. Vivian's school recently studied a science lesson on distinguishing between plant and animal cells. Observation of pupils indicated that learning was occurring, but the enthusiasm they had exhibited in earlier science lessons was obviously lacking. Article discussed a model, designed to stimulate learning processes, from…

Historical uses of Arum maculatum (L.) are summarized. Temperature changes during spadix maturation, spathe uncurling in the presence of flower tissue, indol-3-y1 acetic acid, and gibberellic acid are investigated in the laboratory. Dilute solutions of both phytohormones cause significant spathe uncurling. Further investigations are suggested.…

This paper lists 35 studies in biology which can be tailored to suit the full range of student age groups and are designed to involve most or all of the key elements of the scientific process (study design, data collection and presentation, and experimental manipulation). Examples of some studies are: (1) study the growth of molds on food items…

Describes a Lexington, Kentucky, kindergarten science project that employed the Reggio Emilia approach of long-term open-ended projects steered by children's interests and group discussions. The children's investigation of how caterpillars make cocoons included direct observation of the metamorphosis process, construction of child-sized cocoons,…

Suggests individual student projects for extra-credit work to enhance student individuality. Provides a sample information sheet for independent projects (with suggested activities), a listing of project requirements, and a project evaluation checklist. (DS)

This document presents a science project appropriate for lower elementary grades which is intended to introduce the ways of science, not to give established information or teach specific procedures. Each activity (corresponding to 10 days) contains three sections: teacher notes, teacher narrative, and research notes. Sample activities include: (1)…

Individualized biology activities for secondary students are presented in this teaching guide. The guide is divided into five sections: (1) investigating bread mold; (2) investigating transpiration; (3) completing a botany project; (4) collecting, preserving, and identifying leaves; and (5) writing up science laboratory investigations. The…

Describes a contest where sixth-grade students observe the results of a week of planning, folding, testing, and comparing their best paper frog designs and hopping techniques. This integrated unit helps children unleash their imaginations and develop problem-solving skills. (PR)

Describes a class project to determine which environmental condition, such as light, heat, and type of basking substrate, would result in the least and most turtle basking behavior. (PR)

Describes several student-tested activities built around "Jurassic Park." The activities feature students engaged in role-playing scenarios, investigative research projects, journal writing and communications skills activities, cooperative learning groups, and learning experiences that make use of reading skills and mathematical knowledge. (PR)

This manual presents a variety of ideas for environmental education projects that range in duration from two weeks to several years. All of the projects are designed to make learning interesting and relevant to the lives of students by enabling them to develop a sense of connection to their world and a framework that empowers them to make positive…

Uses shoeboxes to set up science kits to supplement specific areas of the science curriculum. Each kit contains a set of material and instructions for a single activity. The activity is intended as an individualized experience that is related to a current topic of study or that reinforces a recent topic. Details for making six sample shoeboxes are…
