Herbivores are important to ecosystems because they transfer energy stored in plant matter to other organisms. However, when herbivores occur in high abundances, they can become pests and harm the plants that form the basis of food webs. Mangroves are saltwater tolerant trees found along most tropical and subtropical shorelines. Because mangroves…

Most plants are able to obtain all of the nutrients that they need from air, water, and soil; however, this is not true of carnivorous plants. Because they tend to live in boggy soils where there are small amounts of nitrogen, carnivorous plants have developed specialized structures that enable them to lure and capture insects and sometimes other…

In light of increasing populations and dwindling natural resources, elementary teachers play a crucial role in ensuring children understand and commit to more sustainable lifestyles. Climate change, growing pressures on global fisheries, and the harmful effects of traditional agricultural methods exacerbate this call. Coupled with this emphasis is…

This article describes a hands-on science curriculum used to teach kindergarten students about decomposition at the Riverdale Country School in the Bronx, New York. The goal was to get students to spend more time in the natural world and to have the opportunity to literally "get their hands dirty." This was premised on the idea that the…

Children are naturally curious about the world in which they live. To focus this sense of wonder, have your students investigate their local habitat as it changes over the year. This multiseason study will build connections and add relevance to the habitats that children learn about. This series of activities for grades 4-6 explores the changing…

The creation of schoolyard gardens is a growing movement in the United States and around the world (Ballard, Tong, and Usher 1998; Pope 1998; Lewis 2004). It brings together all of the features of authentic hands-on science: Students can collect data on plant growth, observe the plant and animal interactions in the garden, and acquire a sense of…

Describes the Sonoran Desert, the hottest desert in North America. Discusses management challenges, recreation, exotic plants, threatened and endangered species, American Indian traditional cultural places, and riparian areas. Presents classroom activities aimed at educating youth about the area's many distinctive features and the importance of…

Up to 33 million species share the earth; no one knows the exact number for sure. All over the world, many species are becoming extinct. This workbook is designed to help children become more aware of the concept of extinction, and to develop personal strategies for helping with the problem of endangered species. Included are 31 activities…

Evaluated is the impact of the landscape upon children in 21 schools in England. Past and present experiences of 8- to 11-year-old children were measured. Results indicate that both past and present experiences make a small but significant contribution to the children's development of botanical knowledge and environmental dispositions. (Author/CW)

Tree rings can be used not only to look at plant growth, but also to make connections between plant growth and resource availability. In this lesson, students in 2nd-4th grades use role-play to become familiar with basic requirements of trees and how availability of those resources is related to tree ring sizes and tree growth. These concepts can…

The purpose of this curriculum guide is to help teachers implement the Alabama Course of Study: Science. The major emphasis of the guide is to provide student-oriented, hands-on activities that engage students in "sciencing" behaviors. This guide has two major components, the table of contents and the activities. The table of contents…

Through direct experience within natural settings, outdoor education allows students to learn about environmental concerns such as migration of birds, weather systems, wildlife habitats, watersheds, soil erosion, geological formations, food chains, and community resources. All subject areas in the present curriculum can be enriched through outdoor…
