We present our work on a hybridized undergraduate research model that blends the apprenticeship model with that of a course-based undergraduate research experience (CURE) to produce the course apprenticeship-based model (CAB). The purpose of CAB was to incentivize students' interest in undergraduate research at an urban associate granting…

Strong evidence from recent brain research shows that the intentional teaching of science is crucial in early childhood. "Big Science for Growing Minds" describes a groundbreaking curriculum that invites readers to rethink science education through a set of unifying concepts or "big ideas." Using an integrated learning approach, the author shows…

An exercise that provides a hands-on demonstration of the hydrolysis of aspirin is presented. The key to understanding the hydrolysis is recognizing that all six process may occur simultaneously and that the observed rate constant is the sum of the rate constants that one rate constant dominates the overall process.

Texas has opened the door to electronic instructional media, allowing science students new ways to explore the world. Hands-on activities make science concepts real. Videodiscs provide teachers with rich instructional material, displaying still shots, graphics, and film clips on monitors. Students can now explore extreme weather conditions,…

Describes a miniscience unit on frogs for elementary grades that teaches students about how frogs develop from tadpoles and how frogs need water during their entire life cycle. Students learn such skills as observation, collecting, and recording data. Provides addresses for ordering resources for teachers and students. (SM)

Presents activities that focus on shadows to teach about seasonal changes and the earth's tilting axis. Includes suggestions for indoor discussions, diagrams, and models, and for outdoor observations and measurements of shadows. (SV)

An enzyme exercise to address the problem of students inability to visualize chemical reaction at the molecular level is described. This exercise is designed as a dry lab exercise but can be modified into a classroom activity then can be augmented by a wet lab procedure, thereby providing students with a practical exposure to enzyme function.

One of the most basic concepts related to force and motion is Newton's first law, which essentially states, "An object at rest tends to remain at rest unless acted on by an unbalanced force. An object in motion in a straight line tends to remain in motion in a straight line unless acted upon by an unbalanced force." Judging by the time and space…

Explains the fight or flight reaction and presents a hands-on activity for high school students. Uses crayfish behavior as an example. (Author/SOE)

Hands-on experience lets students explore, discover, and think their way through science. The article explains why hands-on science works, presenting tools for getting started with few resources. Activities have students work with the environment in their backyards and the schoolyard. Resources for hands-on science are presented. (SM)

Four elementary teachers present earth-friendly ideas to help students explore nature: creating suncatchers out of pressable outdoor items; making and filling nature explorer kits; producing ecology booklets with covers; filling shoeboxes with natural materials to make rhythm instruments; and making crayon rubbings of outdoor items. (SM)

Several hands-on whole science activities help elementary students learn about animals' diets and how they affect other animals. One activity involves identifying animals as carnivores, herbivores, or omnivores. Another has students construct food chains. Two across-the-curriculum ideas involve naming carnivores and preparing imaginary menus for…

Field trips allow students unique access to resources not available in the classroom. Field experiences enhance students' understanding, are a factor in retention, can be motivational, and are essential for the acquisition of basic science skills. Students learn, in a meaningful way, the procedures of setting goals, observing and recording data,…

In this article, the author first provides the history of the wedding rice myth. He then details an interactive class activity that involved students in his large, non-majors biology classes. These students developed a series of experiments that scientifically determined if rice could be harmful to birds. Finally, he provides suggestions on how…

Article discusses the four elements of good elementary science programs and offers ideas for creative hands-on science and across-the-curriculum activities (e.g., a please touch science center, curriculum planning chart, and getting to know you water activity). It notes science-related events and describes four science reference books. (SM)
