Describes an activity in which students make careful observations about earwigs, then design their own questions for further investigation. (WRM)

Describes a novel course in first-year undergraduate practical biology that introduces students to the principles and practices of a variety of biological techniques. (CCM)

Describes a project in which undergraduate students learn ecological principles and methods by contributing to research involved in restoring an old agricultural field to mesic property. Finds that the project enhances student motivation and interest. (Author/WRM)

Details the construction and design of two kinds of sundials appropriate for school or home use. (Author/WRM)

Describes some experiments that can be performed at home to illustrate what makes popcorn "pop". (WRM)

After taking an environmental inventory of their community, seventh-graders in a Denver-area middle school decided to tackle the drinking water problem and fix it. The school is one of seven participating in Earth Force, an environmental and community-service-learning program based in Alexandria, Virginia. The program's progress and six-step…

Describes how a group of teachers sought to overcome the difficulties of major innovation by working with a change agent to critique their current practice, devise a more authentic science for school science, and implement their ideas. Contains 36 references. (DDR)

Describes the construction of a timer to determine reaction time for use in life science classes. Uses a computer program with a menu that suggests specific experiments. (DDR)

Reviews the requirements of the National Titration Competition and describes how a team in a local competition used the technique. Compares microscale titration to conventional titration. Outlines the benefits of employing microscale techniques. (DDR)

A biotechnologist-turned-teacher introduces a series of laboratory modules incorporating concepts from microbiology, cellular biology, molecular biology, biochemistry, and evolution. The Amylase Project aims to distill the biotechnology process into a few short steps using amylase, the easiest enzyme to detect of those commonly produced by…

Recommends beginning certain chemistry courses with revision and consolidation of mole calculations. Argues that by choosing examples related to health and safety, mole calculations can be made less academic while raising student awareness of important issues. (DDR)

Describes a laboratory exercise that simulates the spread of an infectious agent among students in a classroom. Uses a modified Enzyme Linked ImmunoSorbent Assay (ELISA) to provide students with experience using an authentic diagnostic tool for detecting human infections. (DDR)

Recommends the use of beans as an inexpensive, durable, and readily available resource for developing science-process skills in K-8 students. Shares strategies for using beans in graphing, patterning, and classifying. (DDR)

Presents a weeklong earth science module that allows students to explore the relationships between natural and manufactured materials. Relates rocks and minerals in the earth science curriculum to observations students make in their urban and suburban travels. (DDR)

Describes the SCI-FEST (Science Collaborative Initiative-Festival to Enhance Science and Technology) where community members worked together to put on a successful science festival for the whole family. Discusses the planning and implementation of the festival which included nearly 100 hands-on science activities, skits, puppet shows, and…
