Describes types of meteors and micrometeorites that enter the Earth's atmosphere. Presents an activity where students collect micrometeorites with a strip of tape in an undisturbed outdoor area. After 24 hours, they examine the tape by sandwiching it between 2 glass slides and view through a microscope at 100X. (PR)

Presents five hands-on activities that allow students to detect, measure, reduce, and eliminate moisture. Students make a humidity detector and a hygrometer, examine the effects of moisture on different substances, calculate the percent of water in a given food, and examine the absorption potential of different desiccants. (MDH)

Reports on the effects of a problem-solving-based instructional model on earth science students' (n=172) achievement and alternative frameworks. Results revealed that the problem-solving-based instructional model significantly improved the achievement of students, especially at the application level. Students in the treatment group experienced…

Describes a way to demonstrate the causes of seasons and related phenomena by using an umbrella and flashlight. (WRM)

Lists outstanding science trade books for children in the categories of Biography, Earth and Space Science, Integrated Science, Life Science, Physical Science, and Technology and Engineering. Explains the book selection process. (YDS)

Describes a project in which students developed an all-class laboratory activity called "The Decomposition of Organic and Inorganic Substances in a Landfill". Explores what conditions are necessary to facilitate decomposition in a landfill. (SAH)

Describes how to fit binocular observations of the planets to a theoretical model of circular orbits using a modern computer spreadsheet, from which fundamental data about the solar system may be deduced. (AIM)

Describes how a spreadsheet is used to fit a circular orbit model to observations of Jupiter's moons made with a small telescope. Kepler's Third Law and the inverse square law of gravity are observed. (AIM)

Recommends using science fiction television episodes, novels, and films for teaching science and motivating students. Studies Newton's Law of Motion, principles of relativity, journey to Mars, interplanetary trajectories, artificial gravity, and Martian geology. Discusses science fiction's ability to capture student interest and the advantages of…

Points out the importance and use of Earth's rock and mineral resources in our daily lives. Lists websites on mineral resources. (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)

Introduces the Earth Science Summer Institute for elementary teachers, a program of professional development in content and inquiry. Focuses on concepts and learning demonstrating the interconnectedness of earth science topics. (Author/YDS)

Explores the prior knowledge children from Key Stage 2 (7 to 11 years) at one school in England had of rock classification and how they developed a more scientific understanding using strategies shown by research to support understanding. Findings for 60 Year 5 and 6 students show the importance of providing students with a conceptual model and…

Discusses the misconceptions revealed by the teachers' answers and outlines more accurate answers and explanations based on established evidence and uses these to provide a more complete understanding of plate tectonic process and the structure of Earth. (Author/YDS)

Investigates student learning that occurred with a Geographic Information Systems (GIS) based module on plate tectonics and geologic hazards. Examines factors in the design and implementation of the materials that impacted student learning. Reports positive correlations between student' spatial ability and performance. Includes 17 references.…
