| The following reports are three-dimensional, cut-and-paste paper models and computer animations illustrating geologic processes and other geologic phenomena. Both paper copies and electronic diskette versions are available. Both versions have the same patterns and text, although the diskette version may have animations that describe geologic processes. Requirements for using the diskette version are Apple Computer, Inc.; HyperCard 2.2 software, and an Apple Machintosh computer with an internal disk drive. If you are using System 7, we recommend having at least 8 MB of physical RAM with 4.5 MB of memory available for HyperCard. |

| Antarctic Ice Sheet |
Illustrates, through computer animation and a paper model, why there are changes on the ice sheet that covers the Antarctic continent. By studying the animations and the paper model, students will better understand the evolution of the Antarctic ice sheet.
|
|
| Sand Dunes |
Illustrates, through computer animation and a paper model, why sand dunes can develop different forms. By studying the animations and the paper models, students will better understand the evolution of sand dunes.
|
|
| Karst Topography |
Illustrates, through computer animations and a paper model, why caves develop in limestone. By studying the animations and the paper model, students will better understand the evolution of karst topography.
|
|
| Chicxulub |
This report contains two paper models and computer animations which help illustrate how dinosaurs may have become extinct as a result of an asteroid impact.
|
|
| Crinoids |
This report shows, through computer animations and a paper model, how crinoids lived and became fossilized.
|
|
| Ocean Trenches |
This report contains computer animations and a paper model illustrating how a subduction zone works. Students will better understand the processes that operate at converging margins between tectonic plates and how ocean trenches and the volcanoes associated with them are developed.
|
|
| Arctic Delta Processes |
This report shows, by means of a computer animation and paper models, how deltas are affected by fresh and salt water currents, topography, and location. It is intended to help students visualize how ice shapes form a delta.
|
|
| Sea-Floor Spreading: A Computer Animation and Paper Model |
Distributed with a Macintosh compatible 3.5-inch diskette, along with the paper copy.
|
|
| Make Your Own Paper Fossils |
This report contains animations and paper models of two fossils.
|
|
| Northridge, California Earthquake of January 1994 |
This report contains animations and a paper model of the Northridge, California earthquake.
|
- OF 94-214 A, paper copy, 30 p., $4.50
- OF 94-214 B, 3.5-inch diskette, $10.00
|
| Make Your Own Earth and Tectonic Globes |
This report contains instructions and two patterns for making a terrestrial globe and a tectonic globe that are glued onto a tennis ball.
|
|
| Landslide Effects |
Description, paper models, and animations of four kinds of landslides: slump, slide, flow, and fall.
|
|
| Earthquake Effects: A Computer Animation and Paper Model |
Illustrates by paper model and computer animation how an earthquake occurs and what types of damage may result.
|
|
| Map Projections |
Describes and illustrates four main types of map projections commonly used to present thematic data.
|
|
| Make Your Own Paper Model of a Volcano |
Shows the inside and outside of a stratovolcano and includes a glossary of volcanic features.
|
|
| Island Coral Reefs |
Comprises four paper models that describe island reefs. The first model is a shield volcano that extends above the sea level, the second is a volcano with a fringing reef of coral, the third is a volcano with a coral reef and a lagoon, and the fourth is an atoll.
|
|
| How to construct seven paper models that describe faulting of the Earth |
Describes normal, reverse, right- and left-lateral strike-slip, and oblique-slip faults, and includes models of two fault-produced landforms a graben and a horst.
|
|
| Fault motion Loma Prieta, California earthquake of October 17, 1989 |
Contains instructions and patterns for preparing a three-dimensional model that schematically illustrates the fault motion that occurred during the earthquake.
|
|
| Effects of ice on a mountain valley |
Includes two models showing a mountain valley partly filled by a glacier and the same valley after the glacier has melted.
