Earth Forces—Stream Tables
Stream Table
An affordable and well-made stream table with impressive features! Five different
water jets provide a wide range of flexibility, allowing you to demonstrate erosion,
drainage, delta formation, stream processes and more. Students can clearly see
sediment layers through clear acrylic sides. Create variable slopes by raising or
lowering the table with the adjustable height bar. Smoothly turn the jets on and off
using easy-to-turn valves. Simple to set up—all you need is water and sediment!
Provided pump generates a consistent water flow. Includes a built-in sediment
trap to prevent clogging and a removable dam to create lakes and deltas. Sand is
available separately. Folds for storage. 48" x 20".

Select the Right Binocular—
What does 10 x 25 mean?
The first number (10X) tells you how much the object being viewed is magnified. 10X would
make the object appear ten times larger or ten times nearer than it does to the naked eye.
The practical limit to magnification for a hand-held binocular is 10X. Instruments with a
magnification greater than 10X simply can not be held steady enough for a clear, still image
and must be tripod-mounted or otherwise stabilized.
The second number (25) refers to the diameter in millimeters of the paired objective lenses.
This measurement effectively determines both the field of view and the light-gathering ability
of the binocular. Field of view (the width of the visual field seen through the binocular) is
typically
measured at a distance of 1000 yards. Given the same magnification, a larger objective
lens gives a wider field of view. Wide-angle binoculars increase field of view without
increasing objective diameter by incorporating a different optical design. A large diameter
objective also gathers more light—it permits more light to enter the instrument—and is
essential if the binocular is to be used at times when ambient light levels are low.
Don’t make the mistake of choosing a binocular based solely on magnification—bigger is
not necessarily better. For a good all-purpose instrument look for a magnification of 8 or 10X
with an objective lens diameter from 25 to 50 mm.
