Presents a demonstration to show students how wind and temperature can influence the rate of transpiration in a plant. Lists supplies needed and steps for the procedure. (NB)

Introduces an activity in which students analyze satellite imagery to investigate the effects of large-scale phenomena related to oceans. Includes activity worksheets. (YDS)

Presents an activity that addresses cultural differences and diversity through ethnobotany. Offers a multicultural framework designed to develop concepts about plant characteristics and taxonomy. (ASK)

Examines the importance of teaching for active learning. Describes teaching an interactive chemistry course to help students internalize their learning. Changes from a textbook teaching approach to an interactive learning experience. (SAH)

Introduces a group activity in which students build a catapult. Includes a list of materials required for catapult construction and directions for testing. (YDS)

Describes an animal behavior experiment using guppies. Students observe the behavior of a guppy as it feeds on prey and make observations, collect and analyze data, draw conclusions, and design their own experiments. (SAH)

Presents an activity in which students work in cooperative groups and roll balls down inclined planes, collect data with the help of an electronic motion detector, and represent data with a graphing calculator to explore concepts such as mass, gravity, velocity, and acceleration. (Contains 12 references.) (Author/ASK)

Describes activities that link classroom science to real world scientific ventures. Uses field trips to zoos or wildlife centers for in-depth learning experiences that help students observe, investigate, and explore issues in animal science. (SAH)

Presents two exercises on the study of tropisms. Discusses gravitropism control mechanisms present in plants. (ASK)

Presents four exercises on food fermentation. Discuses the principles and processes behind each fermentation reaction. (ASK)

Describes a recovery program for the rodent population on St. Kitts island in the Caribbean. Students read a case study and formulate a story incorporating some of the details and data provided in the story while also drawing on several evolutionary concepts studied in class. (SAH)

Describes an experiment in which students use candy and containers of water to spark their interest in investigating. Students work in groups and make observations about what happens to the candy as it is placed in water. Features an experiment template for students to record their findings. (SAH)

Introduces the MicroObservatory Network of automated telescopes which is designed to provide access to classroom teachers who wish their students to conduct projects over the World Wide Web. Allows students to take pictures with remote pointing and focusing telescopes. Encourages collaboration among schools. (Contains 18 references.) (Author/YDS)

Describes the use of cooperative learning teams as a means of persuading students of different backgrounds and cultures to work together. Presents a cooperative learning activity where students work as a team and observe and identify chemical reactions and physical properties. (JRH)

Presents a three-week interdisciplinary unit for starting the school year that focuses on the concept of flight. Enables students to acquire knowledge and develop process skills that they need later in the semester. (JRH)
