Uses engineering projects to make students create design prototypes of paper airplanes in order to teach the scientific principle of flight. (ASK)

Describes a partnership involving fifth grade students, preservice teachers, a classroom teacher, and a university faculty member in introducing students to the basic anatomy of a cell using three-dimensional models, analogies, and hands-on/minds-on activities. (ASK)

Presents an experiment in which students use laboratory data to calculate the interphase mass transfer coefficient for a fluid passed over a sphere and obtain correlations for solid-gas mass transfer. Students develop a realistic mathematical model to describe the sublimation process. (DDR)

Recommends the use of a model of DNA made out of Velcro to help students visualize the steps of DNA replication. Includes a materials list, construction directions, and details of the demonstration using the model parts. (DDR)

Presents an activity on the electrostatic phenomenon known as induction. Reviews the principles illustrated by each of the activities described in this series. (DDR)

Elementary teachers can use weather folklore to help students explore and discover facts about weather. An experiment with woolly bear caterpillars examines whether their stripes can predict what kind of winter weather there will be. A investigation about moon halos and rain gives students experience setting up investigations based on questions…

This intermediate-level science activity has students observe the effect of ice-cold water mingling with warm water. Water's behavior and movement alters with shifts in temperature. Students must try to determine how temperature affects the movement of water. Necessary materials include a pencil, cup, glass jar, masking tape, warm water, ice…

Suggests that students can develop the ability to do science in an informal environment such as a zoo, aquarium, or museum. Informal environments provide live organisms, specimens and scientific objects that students can explore and study. (CCM)

Introduces the international science education program Global Learning and Observations to Benefit the Environment (GLOBE). The program is based on the active, hands-on involvement of students and data collected using the scientific protocols file on GLOBE's website. (YDS)

Introduces The Traveling Scientist program which can be used as an extension to the science curriculum. Targets 1st and 2nd grade students. (YDS)

Discusses teaching techniques for teaching about rocks, minerals, and the differences between them. Presents a model-building activity that uses plastic building blocks to build crystal and rock models. (YDS)

Presents a science unit in which students design and test a sample of concrete and later redesign it to improve the strength of their sample under compression. (YDS)

Presents hands-on activities to teach about the causes and consequences of strokes. (YDS)

Describes strategies to introduce students in a first year chemistry course to the gas chromatograph coupled with a mass spectrometer (GC-MS) and provides students with hands-on experiences in its use. (ASK)

Presents two components of a piece of experimental equipment, the optical training ground and the electrical panel, which can be used to construct and test different electrical circuits and study laws of electricity, experimental problem solving, and basic light phenomena. (YDS)
