Presents investigations in which students are provided with a series of four mystery items related to cicadas. Observations and a class discussion follow each item. Contains basic information on doing experiments with live cicadas, specific assessment strategies for this activity, and facts about cicadas. (DDR)

Provides background information on the Science Education Quantitative Literacy (SEQL) project that is designed to enhance student laboratory experiences by working together on data collection and analysis. Includes details of an activity from the project curriculum on how many drops of water can be placed on a penny. (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)

Details an activity in which students create and study miniature impact craters in the classroom. Engages students in making detailed, meaningful observations, drawing inferences, reaching conclusions based on scientific evidence, and designing experiments to test selected variables. (DDR)

Presents a unit that focuses on landslides and integrates earth science, physics, chemistry, and math. Includes activities to investigate porosity, permeability, cohesion, saturation, and gravity. (JRH)

Presents an activity from the track and field unit of the Science of Sporting Events program in which teachers and students experiment with four broad jump techniques in order to determine which method will allow them to jump the farthest. Enables students to use a variety of math and science skills including observing, predicting, measuring, and…

Discusses the use of games in the science classroom as a productive, motivating tool. Presents games that require abstract thinking and that change potentially boring exercises into challenging competitions. (JRH)

Argues for an emphatic role for theory in everyday science teaching. Contrasts science's confidence in its theories with those of other sorts which students encounter in their everyday lives. Discusses common denominator science teaching in which teachers teach science in units based on different sciences. (DDR)

Describes the recent history, chemistry, and educational uses of the Orange Juice Clock demonstration in which a galvanic cell is made from the combination of a magnesium strip, a copper strip, and juice in a beaker. Discusses the chemistry basics, extensions for more advanced students, questions for student/teacher workshop participants, and…

Presents activities that allow students to think about the Earth in a contextual manner and become familiar with constructive and destructive processes as they relate to sand - its origins, cyclical processes, and yielding of new products. Explores the bigger idea with a developmentally appropriate study of water, rocks, sand, physical phenomena,…

Recommends the use of role-playing as an effective summative activity that aids student learning and integrates science information and concepts. Describes the use of a role-play activity related to Senate hearings. (DDR)

Recommends the use of origami to construct models of unit cells and crystalline structures. Provides templates and suggestions for use with students. (DDR)

Presents a real life shark attack story and studies arm reattachment surgery to teach human anatomy. Discusses how knowledge of anatomy can be put to use in the real world and how the arm functions. Includes teaching notes and suggestions for classroom management. (YDS)

Points out the importance of having instructional materials on the contributions of culturally diverse groups to science and technology for student learning. Describes efforts to create interdisciplinary activities that promote critical thinking among students and focuses on pre-Hispanic and colonial periods in the history of Mexico. (YDS)

Reports on a study that explored the types of questions that students ask for open-ended science investigations. Discusses how teachers can help students identify problems and pose questions that are feasible for investigation. (Contains 55 references.) (DDR)
