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

Describes a seventh-grade science course that is based on the phenology of the seasons, uses the outdoors on a regular basis, and uses reference books and field guides. (DDR)

Presents a modification of a procedure for making and launching hot air balloons made out of garbage bags. Student instructions for balloon construction, launching instructions, and scale diagrams are included. (DDR)

Presents a unit on motion that allows students to apply what they learn from doing hands-on, minds-on activities, a key component of the National Science Education Standards. Also includes examples of the assessment instrument. (DDR)

Provides details of an activity in which students spear a toy fish and learn about the refraction of light. Plans for the sighting apparatus and for making the toy fish are included. (DDR)

Presents hands-on activities that give students a head start in learning the vocabulary and basic theory involved in understanding atomic structure. Uses beads to represent protons, neutrons, and electrons and string to represent orbitals. (DDR)

Recommends that teachers try putting a new twist on classic experiments to focus and motivate students to learn science. Argues that dissonance or discrepancy can be introduced into many activities. Focuses on gloop (a puttylike substance). (DDR)

Provides an example that focuses on temperature and illustrates how in-depth study can meet multiple content standards for middle school science and mathematics in the subjects of measurement and data analysis. (DDR)

Explains the development of an interdisciplinary unit in which students learn basic chemistry and laboratory techniques while practicing English, mathematics, art, social studies, and leadership skills. Includes details about lab activities, assessment strategies, and science extensions. (DDR)

Details the experiences of a teacher who spent a month on a National Oceanic and Atmospheric Administration (NOAA) ship. Reports observations of developing El Nino conditions and presents related classroom activities. (DDR)

Focuses on an experimental vegetable garden project in which grade eight students test their hypotheses on plant growth under variable soil conditions. Provides opportunities to integrate various scientific topics. (DDR)
