Presents ways to use ChiaPets to link biology-related topics such as taxonomy, morphology, ethnobotany, economic botany, hydroponics, salinity, photomorphogenesis, and phototropism with food and fertilizer chemistry, mathematics, art, and history. (MKR)

Presents 12 discrepant event demonstrations on various concepts related to density to make physical science more interesting and fun. Demonstrations are organized into the "5E" instructional model (engagement, exploration, explanation, elaboration, and evaluation). (MKR)

Presents activities using thermocouples to investigate the temperatures at which candles burn and popcorn pops. (MKR)

Presents an activity that aims at enabling students to recognize that DNA and RNA are information molecules whose function is to store, copy, and make available the information in biological systems, without feeling overwhelmed by the specialized vocabulary and the minutia of the central dogma. (JRH)

Describes the construction and operation of an apparatus used to study the optical properties of solids using reflection. (JRH)

Discusses the use of high school students to present physics demonstrations to first graders. (MKR)

Presents an activity that highlights the life of Harriet Brooks, a lesser-known Canadian physicist. Objectives include stressing Harriet Brooks's contribution to science and developing a historical connection to other prominent figures, illustrating to students that attitudes about women in science were very constraining in Harriet Brooks's time,…

Presents an effective way to start a technological revolution in schools by beginning with a single exciting project that incorporates new technologies and then letting interest in the project prompt others to action. (JRH)

Discusses the properties of neodymium magnets and magnets in general and how magnets can be used to teach students important scientific principles, such as attraction, repulsion, and polarity; the role of magnetic forces in electronic communications and computers; the magnetic properties of the earth and compasses; and the relationship between…

Describes activities for helping children develop skills in quantitative observations. (PR)

Discusses the importance of teaching young children to appreciate and care for the earth and how to integrate earth activities into the curriculum. Includes a year-round curriculum with ideas for hands-on activities appropriate to each month, an integrated unit called "Flowers Blooming," tips for evaluating science experiences, and a…

Gardening helps children learn how plants sprout, grow, bloom, and then wither away, leaving seeds behind. Participating in this natural process allows children to experience the stages of life. Suggested gardening activities include studying dandelions, focusing on culture for garden plant selection, and constructing a worm box or worm terrarium…

Discusses how teachers can introduce students to various scientific concept concerning motion, air composition, and heat by conducting an experiment: A peeled, hard-boiled egg is sucked into a bottle neck slightly smaller than the egg, after the bottle has been filled and emptied of hot water. Also discusses how students' understanding of the…

Describes geography activities for elementary students. In the first activity, students learn how to understand coordinates and use them to read maps. In the second activity, students learn the concepts of the legend as well as how to use it to find their way around on a map. (PR)

Describes introducing students to the chemical elements through the use of Tom Lehrer's recording of "The Elements" and through the use of the game "20 questions." By asking the teacher questions about an unknown element or compound, students are given opportunities to develop and practice analyzing, synthesizing, and…
