A survey and exploratory study were conducted to analyze Lake Tempe as a resource for contextual learning (CTL). The first phase of the study included exploring the lake's potential through interviews with the people who live in the lake's coastal region. Quadrat transects were done to identify aquatic plants around the lake. A feasibility…

Ecological ponds can be a good teaching tool for science teachers, but they must be built and maintained properly to provide students with a safe and suitable learning environment. However, many schools do not have the ability to build and maintain an ecological pond. This study used virtual reality technology to develop a web-based virtual…

Aquatic plants can be divided into two types: algae and macrophytes. The goal of aquatic plant management is to maintain a proper balance of plants within a lake and still retain the lake's recreational and economic importance. Aquatic plant management programs have two phases: long-term management (nutrient control), and short-term management…

This publication, produced by the Pennsylvania Cooperative Extension Service, is a non-technical guide to chemical control of aquatic vegetation. The purpose of this circular is to aid the land owner or manager in managing ponds, streams, and other water bodies for desired uses by managing the vegetation in, on, and around the water. Among the…

This study has three major purposes, including designing mobile natural-science learning activities that rest on the 5E Learning Cycle, examining the effects of these learning activities on students' performances of learning aquatic plants, and exploring students' perceptions toward these learning activities. A case-study method is utilized and…

This agriculture extension service publication from Pennsylvania State University is a handbook for the water body manager. The bulk of the contents deals with aquatic plant control. The different types of aquatic plants, their reproduction and growth, and their role in the ecology of the water body are introduced in this main section. Also, the…

Describes using the aquatic plant, duckweed, for open-ended investigations and learning about factors important in photosynthesis. (PR)

Describes an experiment to investigate chemical changes, pH, dissolved oxygen content, light intensity, and temperature in water containing aquatic plants. (MKR)

Describes the nature of wetlands (low areas with shallow water or water-soaked soils supporting aquatic and semi-aquatic plants) and suggests wetlands topics and activities for science, history, and language classes. (Author/SK)

Explains the process of developing the unit "Building an Aquarium" and introduces four hands-on activities which include teaching students how to read a metric ruler, observing and illustrating an aquatic plant, learning fish anatomy, and learning animal behavior. (YDS)

Discusses problems in selecting the correct herbicide for use in controlling aquatic weeds, considering specificity, size of the market, fear of trace contaminants, and herbicide resistance in weeds. Also summarizes some successful herbicides, providing a table listing mode of action of some herbicides used for control of aquatic plants. (JN)

Physical, chemical, and biological effects on macrophytes (aquatic plants) on the freshwater ecosystem are discussed. Research questions and issues related to these organisms are also discussed, including adaptations for survival in a wet environment, ecological consequences of large-scale macrophyte eradication, seasonal changes in plant…

Presents biology, chemistry, physics, and health activities, experiments, demonstrations, and computer programs. Includes mechanism of stomatal opening, using aquatic plants to help demonstrate chemical buffering, microbial activity/contamination in milk samples, computer computation of fitness scores, reservoir project, complexes of transition…

Designed to acquaint students in grades 4-9 with aquatic plants and animals, this guide provides materials which can be used in preparation for field trips or laboratory work, for individual projects, as supplemental activities for a unit, or for learning center projects. Teacher background notes and an answer key for the student activites are…

Included in this bibliography are annotations of quantitative data on the content or concentration of nitrogen and phosphorus in plants and animals, the contribution to water of these elements from various sources (soil, fertilizers, excretion, sewage, precipitation, urban run-off), and the effect their presence has on aquatic standing crops and…
