In this fourth and fifth grade activity, students become comfortable with the concept that light-years are a measure of distance, not time, and discover how we are looking back in time when we look at stars. Since the enormous distances in space can make astronomical studies even more confusing, students explore the meaning of a light-year by…

Cultures need to accurately record dates and times for various societal purposes, ranging from knowing when to plant crops to planning travel. In ancient times, the sun and moon were used as measurement devices because of the scientific understanding of the physical world at that time. Ancient timekeepers monitored celestial events and either used…

When students are first introduced to the idea of radioactive decay, a large conceptual hurdle must be overcome. The thought that an object's age has no bearing on the chance it will "die" (decay in this case) on a particular day is completely at odds with biological notions of life and death. Through the use of a simple…

The activity described in this article engages students in learning about proper meat storage procedures by using the Internet. They apply their knowledge practically through creation of a pamphlet to be displayed in their kitchen at home and a follow-up report on their parents' kitchen procedures; they may also participate in a classic food…

The thought of learning about the principles of classical management and the machine metaphor of organizing can get many organizational communication students yawning just by seeing the subject in a syllabus. Abundant movie and television examples associated with the machine-like nature of workplace productivity are often used to demonstrate…

Discusses the semantic functions of the English future formations: "will/shall,""to be going to," and the present tense. Points out that these all have modal as well as temporal significance, making the traditional teaching of the English future imprecise and misleading. (IFS/WGA)

Ligand binding is generally explained in terms of the equilibrium constant K[subscript d] for the protein-ligand complex dissociation. However, both theoretical considerations and experimental data point to the life span of the protein-ligand complex as an important, but generally overlooked, aspect of ligand binding by macromolecules. Short-lived…

Presents many activity ideas for teaching young children about time using chronological events, clocks, and calendars. Jerome Bruner's enactive-iconic-symbolic sequence of concept development is used as a guide for these learning experiences. (LP)

Learning disabled students who know how to tell time may still need instruction in using time in practical situations. Such instruction should focus on skills such as determining the amount of time between two given times, approximating time requirements for recurrent tasks, and predicting time (CL)

An approach to teaching time telling to learning disabled children begins with the child drawing a clock, then designating 5-minute marks, using old alarm or play clocks to manipulate the hands, and drawing clock hands to represent specific times. (CL)

Reviews the conceptual and developmental issues associated with learning time concepts. Demonstrates how important time concepts are to all subject areas and provides an analysis of the use of time concepts in two widely-used standardized tests. Offers six guidelines for teaching time concepts to children and illustrates these guidelines with…

Presents a course, Physics and Time, that centers on a few topics that students with limited mathematics training and no previous science can explore in depth. Discusses concepts of time, measuring time, arrows of time, and linearity versus nonlinearity. (JRH)

The article reviews traditional analog time-telling instruction and introduces an alternative approach for learning disabled and other mildly handicapped students. The applied digital approach couples concrete instructional techniques with murals depicting time-related actions of student's day. (CL)

Discusses several projects to help teach and reinforce the concept of time, using the books "The Very Hungry Caterpillar" (by Eric Carle) and "Charlotte's Web (by E. B. White) as well as the computer software program "Timeliner" (by Tom Snyder). (SR)

Presents activities for studying metric time where time is divided using base 10. (ASK)
