This study examined 6th graders' use of the VoiceThread app as part of a science inquiry project on photosynthesis and carbon dioxide emissions in terms of their ability to engage in causal reasoning and their use of the affordances of multimodality, collaboration, interactivity, and connectivity. Students employed multimodal production using…

Taxonomic education and botany are increasingly neglected in schools and universities, leading to a "missed generation" of adults that cannot identify organisms, especially plants. This study pilots three methods for teaching identification of native plant species to forty-three adults engaged in the participatory science project…

Methods of investigating plant root growth developed for research purposes can be adopted for student use. Investigations of the effect of water table level and of ethylene concentration are described, and techniques of measuring root growth are explained. (Author/ML)

Provided are two experiments which deal with the formation of callus and embryos from tissue culture of carrot roots. Outlined are the purpose, materials, procedure, and results for each. (RT)

Describes an outdoor classroom curriculum project which was devised to accommodate students of average and below-average academic ability and provide them with practical horticultural experiences. Discusses funding, plant facilities, program, and resultant products. (RT)

Reports on an investigation of a population of dandelions on a school lawn. Describes the objectives, rationale, study area, and the results of the study. Includes tables and graphs that show data collected. (RT)

The Learning in Science Project (Primary)--LISP(P)--investigated the ideas and interests children have about flowering plants (in particular whether these plants have a life cycle). Data were obtained from: individual interviews with children, ages 7- to 14-year-old (10 students for each age level), using the "interview-about-instances"…

Describes a multidisciplinary unit which uses 12 varieties of apples. Explains activities for observing, predicting decay, art and science, the process of fermentation, and group and individual projects. Information on description of apples and labeled diagrams are included. (RT)

This teacher's guide suggests activities that provide a wide range of opportunities for children in grades 1-7 to plan, direct, and carry out experiments with seeds and the growth of plants. Photographs are provided and methods discussed for guiding students in exploring the growth of seeds, the effect of dark on growth, factors causing plants to…
