Tectonics Model—
Demonstration Kit
By: The Flinn Staff
Demonstrate the powerful forces of tectonic processes with this easy-to-use, handson
model. Brightly colored sand simulates the formation of folds, faults, erosion and
rift valleys. Student worksheets and teacher’s guide provide detailed discussion and
analysis of continental drift, convergence, divergence, the Earth’s surface and other
related concepts. 13" L x 71/2" W x 4" H.
Note: Replacement tectonic sand is available separately.

Coriolis Effect Apparatus
How does the Earth’s rotation affect objects moving over its surface? This kit allows
students to observe the Coriolis effect simply and clearly with a 3/4"-diameter steel
ball and a revolving turntable that shows a visible yet erasable mark from the ball’s
path. See how the ball’s path is unaffected when the platform is static, but curved
when the platform is revolved to simulate the Earth’s rotation. Activity sheets guide
students as they investigate the Coriolis effect in the Northern and Southern hemispheres
and observe its influence on atmospheric circulation. 14"-diameter platform.
This kit will serve one lab group of 3–4 students.

AP5113 Coriolis Effect Apparatus $47.90
Contour Model Kit
Students draw contour lines on the 3-D plastic model by progressively adding
water to the box, centimeter by centimeter. Trace the irregular concentric circles
on the plastic lid and—voila!—watch the contour model appear! Students proudly
compare their map to the provided aerial photograph of Mt. Capulin. Kit includes
transparent molded plastic box containing volcano, transparent plastic lid, metric
ruler, marking pencil and student investigation sheets detailing the activities. This
kit will serve one lab group of 3–4 students.

Density Flow Model Junior
Unique demonstration tank is used to demonstrate hard-to-visualize concepts
related to Geology, Meteorology and Fresh and Saltwater systems. Students will be
introduced to topics such as plate tectonics, thermoclines, air masses, fronts, and
wind and ocean currents, to name a few. Comes complete with detailed 55-page
manual with thought-provoking student activities, teacher setup instructions and
answer key.

Seismograph Model
The model consists of a pen mounted on a weight that is suspended from a frame. A
roll of paper below the pen simulates the recording device. Have a student pull the
paper and—if no vibrations occur—the pen traces a smooth even line. Have a student
cause a simulated earthquake (i.e., vibrate the table), and watch as the support
moves with the tremors and the stationary pen records the “earthquake.” Explain the
similarities of the model to an actual recording apparatus of a seismograph, which is
anchored to bedrock to measure seismic waves, locate the epicenter and determine
magnitude. Included is a teacher manual with easy setup instructions and lessons.
