Observing and documenting elements of weather teach children about using tools and their senses to learn about the environment. This column discusses resources and science topics related to students in grades preK to 2. This month's issue describes an activity where students indirectly document local weather by counting outdoor clothing types worn…

What if you could challenge your second graders to design an outdoor STEM classroom with a butterfly garden, birdbath, and sundial? With this volume in the "STEM Road Map Curriculum Series," you can! "Investigating Environmental Changes" outlines a journey that will steer your students toward authentic problem solving while…

Presents a science activity in which students simulate increases and decreases in frog populations to get a better understanding of different environmental issues affecting animal populations. Includes simulations for both natural frog populations as well as populations affected by human activities. (YDS)

Presents a long-term investigation designed to provide practice for students in thinking in a scientific manner about a real problem--the impact that waste products may have on soil. Focuses on student questions that have some connection to the local community. (JRH)

Describes the construction of an inexpensive light sensor that can be used to measure irradiance in aquatic habitats. Includes a list of tools and materials, details of construction, and usage of the light sensor. (DDR)

This manual was developed for educators and natural resource managers who are establishing interpretive programs where biodiversity is the richest and most threatened. The manual contains five units which are based on the experiences of staff at the American Museum of Natural History and represent the key steps of designing an interpretation…

The Rapid Assessment for Conservation Education (RACE) provides guidelines and tools for identifying conservation education needs and recommending subsequent actions. Interviews, surveys, workshops, and public meetings are among the methods of qualitative and quantitative data collection used to gather information quickly and inexpensively.…

This article examines a decision-making strategy called mixed scanning which can be used to teach social participation in elementary and secondary social studies. The strategy requires logical gathering and analyzing of information, judging the alternatives, making choices, and planning a course of action. The article outlines environmental…

Describes an exercise in which students use a hydrological instrument in an actual field situation to measure stream discharge. (RT)

Elementary teachers can help students consider how much trash they create by analyzing lunchroom waste. Students research the problem, brainstorm lists of items thrown away, and monitor the cafeteria, counting items and collecting data. They enter information into a spreadsheet which the class examines to search for alternatives. (SM)

Reports on a school project that focuses on a lake's ecosystem and engages students in data collection and analysis. Data are shared with the local government to assist with the monitoring of water quality. Includes tips on group cooperation and assessment. (DDR)

Describes an integrated thematic unit for children from kindergarten to third grade. Explains that the unit incorporates reading, speaking, writing, science, mathematics, social studies, and art into the study of whales. Suggests learning activities on echolocation, migration, measurement, scrimshaw, history, and human interaction with the…

This book approaches the development of science fair projects from the point of view that science should be enjoyable, interesting, and thought-provoking. The scientific concepts introduced here will later help young students to understand more advanced scientific principles. These projects develop skills such as classification, making measured…

The teacher's guide of "Assessing Toxic Risk" aims to help students conduct scientific research on relevant environmental topics. Using the research protocols in this book, students learn to carry out experiments known as bioassays. In this way, the toxicity of substances is evaluated by measuring its effect on living things. The text is…

Outlines a science curriculum reform effort aimed at enabling students to collect original data concerning an environmental parameter such as water quality on a yearly basis. Students track the overall health of the stream by analyzing both biotic and abiotic factors. (DDR)
