The evolution of science is seldom about solitary individuals busy at work in labs making discoveries. This is especially true of the Earth sciences, where time-intensive fieldwork is usually required. Single scientists are rarely capable of amassing the requisite data sets to form grand, unifying theories. This is the case with the new airburst…

Introduces a lesson plan on the role of the acorn and its complex community of biotic relationships between animal and fungal organisms. Introduces students to ecological concepts through acorn investigations including dissection of acorns and exploring the organisms' interaction web. (YDS)

Presents an activity in which students in groups explore one planet in the solar system and present their findings to the whole class. Focuses on the planet's location in the solar system, geological features, rate of revolutions, and calendar year. (YDS)

Introduces a unit on the brain and learning styles in which students become aware of their own cognitive styles. Studies the connection between the three senses--sight, touch, and hearing--and three types of learning styles--visual, auditory, and kinesthetic. (YDS)

Uses a teaching approach in which students prepare their own physics activity lesson plans and use them in class with other students. (YDS)

Introduces an activity involving Orson Welles' radio broadcast of the "War of the Worlds" to teach concepts on planets. Provides a lesson plan for grades 5-8 on "War of the Worlds". (YDS)

Discusses the potential contribution of GPS and related Geographic Information Systems (GIS) technology to education. Provides resources for teachers to plan a lesson on exploring with the help of a GPS device in order to increase students' awareness of their surroundings and broaden understanding of their place in the world. (KHR)

Explores role playing as a unique and amusing way of instruction. Describes how to use this method to teach about cells and atoms. (YDS)

Presents lesson plans on bread making using a student-centered approach and process skills. Includes designing the experiment, investigation, and data collection. (YDS)

Integrates math and science through pressure and weight investigations using dancers' feet. Examines pressure by exploring the pressure exerted by a dancer standing on her toes, and investigates weight and measurement. Makes suggestions for assessment. (SAH)

Introduces an activity in which students learn principles of force and motion, systems, and simple machines by exploring the best position of the dogs on the dashboard. Includes a sample lesson plan written in the five instructional models: (1) engagement; (2) exploration; (3) explanation; (4) elaboration; and (5) evaluation. (KHR)

Describes a lesson plan on alien invasions to introduce students to the principles of genetics. Discusses the history of Gregor Mendel, dominant and recessive traits, offspring, and mutations. (YDS)

Presents a class activity in which students use trigonometry to calculate the height attained by a water rocket. Provides a lesson plan that includes a list of materials needed, procedures to carry out the experiment, suggestions to extend the activity, and a reproducible worksheet for the students to register their calculations. (MDH)

Presents three typical lab activities involving the breathing rate of fish, the behavior of electromagnets, and tests for water hardness to demonstrate how labs can be modified to teach process skills. Discusses how basic concepts about experimentation are developed and ways of generating and improving science experiments. Includes a laboratory…
