This study aims to examine the impacts of the inquiry learning strategies employed in a "Plastic Education Project" on primary students' knowledge, beliefs and intended behaviour in Hong Kong. Student questionnaires and a test on plastic types were adopted for data collection. Results reveal that the inquiry learning strategies…

Creating inquiry activities is inherently difficult. Asking meaningful questions requires both background knowledge on the part of the students and complexity on the part of the phenomena. Yet numerous strategies can help teachers conduct inquiry activities. In this article, the authors share a taxonomy of teaching strategies used to create…

Static headspace analysis of accelerants from suspected arsons is accomplished by placing an arson sample in a sealed container with a carbon strip suspended above the sample. The sample is heated, cooled to room temperature, and then the organic components are extracted from the carbon strip with carbon disulfide followed by gas chromatography…

State/representative soil is one of many symbols (e.g., tree, flower, bird, etc.) adopted by citizens to be recognized as an important item to their state. We have developed a set of laboratory exercises, assignments, and exam questions utilizing the state/representative soil that gives college students an opportunity to practice interpretation of…

Uses trenoids, which are toothpicks colored with ink markers to represent a single taxa of organisms to illustrate ecological concepts in a student-centered learning environment. (YDS)

Presents activities that use marine organisms with plant-like appearances to help students build classification skills and illustrate some of the less obvious differences between plants and animals. Compares mechanisms by which sessile plants and animals deal with common problems such as obtaining energy, defending themselves, successfully…

Describes an introductory course in geology for nonscience majors that involves students in laboratory exercises related to rock classification. (GS)

Suggests classroom projects for investigating the diversity of insects. (LS)

Presents a classification scheme for identifying sedimentary rocks in introductory geology laboratories. The key consists of an ordered sequence of tests to perform and observations to make which then suggests a rock name or directs the student to additional tests and/or observations. (ML)

Describes classroom activities using algae, including demonstration of eutrophication, examination of mating strains, and activities with Euglena. Includes on algal morphology/physiology, types of algae, and field sources for collecting these organisms. (JN)

Activities and experiments with leaves are given for use with elementary students. Classifying and measuring are ideas which are suggested for involving children in some in-depth projects with leaves. (SA)

This document contains biology labs, demonstrations, and activities that use low budget materials. The goal is to get students involved in the learning process by experiencing biology. Each lab has a teacher preparation section which outlines the purpose of the lab, some basic information, a list of materials , and how to prepare the different…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide presents activities…

This book is designed to help students understand the nature of scientific inquiry by involving them in doing science rather than merely reading about it. The content of the text emphasizes science process skills, mathematical skills, and the use of theories and models that are fundamental for learning the various science disciplines. The…
