German - Orbiters are scientific working models representing the sun, earth, and moon and their relationships. They are designed to demonstrate basic earth and moon motions and to explain the causes of day and night, seasons, and phases of the moon. Basic Investigations with the Orbiter are: How the earth's rotation causes day and night. How the earth's revolution around the sun and the tilt of its axis causes seasons. Why the sun rises in the east and sets in the west Why there is a midnight sun. Why there are eclipses and More. Numerous study project and experiments may be conducted with Orbiters to expand interest and increase knowledge of the subject. Several ideas and projects are suggested.

This set of 12 Study Prints includes interesting facts and full color illustrations depicting various aspects of astronomy. Great for individual study, small group activities, teacher presentations, or durable eye-catching displays. Students will discover the wonders of our solar system as they travel through each of the 12 study prints. Teacher's Guide includes directions as well as vocabulary.

Light up the Sun with this version of Orbiter. This model can be plugged into a standard wall outlet (UL approved - 6' power cord) to illuminate the Sun to effectively demonstrate daylight, night, seasons, and phases of the Moon. The Sun, Earth and Moon manually revolve around one another on this gear-driven model. The earth and moon are shown in true scale. The scale is 1 inch = 2000 miles. If the sun were to be shown at the same scale, it would be approximately 36 feet in diameter! Arm is 15", Sun is 6", and the Earth is 4" in diameter. This 8 page Lesson Plan includes basic investigations and activities on the following topics..Day and Night.The Seasons.The Moon.Observations and Activities

Insure thorough understanding of the basic concepts of astronomy with this comprehensive set of study aids: Orbiter, Solar System Simulator, Celestial Star Globe, Astronomy Study Prints, and Astronomy I Overhead Transparencies. Contains 1 each of #101, #200, and #300 for big savings!

Illuminated Orbiter for foreign electrical currents includes transformer and adapter for foreign electrical currents. Light up the Sun with this version of Orbiter. This model can be plugged into a standard wall outlet (UL approved - 6' power cord) to illuminate the Sun to effectively demonstrate daylight, night, seasons, and phases of the Moon. The Sun, Earth and Moon manually revolve around one another on this gear-driven model. The earth and moon are shown in true scale. The scale is 1 inch = 2000 miles. If the sun were to be shown at the same scale, it would be approximately 36 feet in diameter. Arm is 15", Sun is 6" and the Earth is 4" in diameter. This 8 page Lesson Plan includes basic investigations and activities on Day and Night, The Seasons, The Moon, and Observations and Activities. For grades 3 to 12 and ages 8 to 18 years.

Bring the mysteries of the solar system into the classroom with a Project Planetarium Set. For individual or small group use, our set lets students plot eclipses, moon phases and planet positions. Includes a study guide, solar system chart and mini Sun-Moon-Earth model. Chart is 17" X 21.5"; Planetarium is 4"L.

This eye-catching 3D wall plaque is a great way to generate interest in the solar system. All eight planets are to scale, respectively, and it even displays Saturn's rings in raised relief! Approximate size is 30" X 36" with hanging grommets molded into the plaque itself. An informative Teacher's Guide is included.

Updated to reflect the current eight celestial planets. (Sorry Pluto!) Designed by AMEP's award winning Graphic Designer, this poster will bring a stunning representation of the Solar System to the classroom. Relative size and distance is explained along with a conversion scale of metric and US units. The number of moons, if any, are shown along with the astronomical symbol. This poster measures 45" x 18". Not laminated.

Our 3-D model promotes basic understanding of cloud types in the classroom or outdoors, in addition to science and math skills. Removable labels let students identify cloud structures and altitude son 24" x 18" model. Includes 3-ring binder with glossary, key, blackline master and a full-color overhead transparency

Study the stars with your own planetarium! This unique 12" diameter globe and 3.3" world globe may be rotated independently. The meridian may be tilted to adjust the globe for latitude while the horizon ring indicates the actual horizon in relation to the point of observation on Earth. The Sun may be set by adjusting the sun knob located near the North Pole. Globe can be set to reflect constellation position according to time and place to show the actual positions of the stars. Globe has been printed on the inside so that a crayon may be used to mark positions of the planets or the moon on the outside. Includes a detailed Study Guide with nine different classroom activities. A National Standards Correlation sheet is included.

This fascinating 7" x 6" device helps students to make real scientific measurements of declination, altitude and azimuth of celestial bodies in order to determine latitudinal position or to observe the motion of the Earth. Measurements of slope, strike and dip of geologic features can also be taken.

Illustrate the galactic mysteries of the universe with this classroom set of work cards. Images have been updated with the latest NASA photography and are printed in full color. Includes teacher's guide. 135 cards (15 each of 9 galaxies). Cards measure 2" X 3.25".

Measure relative humidity with this simple sling psychrometer. Consists of wet and dry bulbs and Celsius thermometers that rotate on aplastic handle. Correlate with other instruments in weather investigations. Set of 15.

Used to examine the process of evaporation and measure humidity, this kit includes a beam balance with wire hangers and a sponge that is cut into two equal pieces.

As the steel spheres track a pattern on the kit's turntable, students simulate the effect of the Earth's rotation on winds, ocean currents and material objects. Includes Teacher's Guide. Set of 10.
