Anemometer
The anemometer is useful for determining wind speed. It is made of corrosion resistant materials for prolonged outdoor use. One cup is red to facilitate the determination of the number of rotations. It is simple enough for students to understand and use, while accurate enough to be used by professional meteorologists in weather forecasting. The unit consists of a pole with rotating suction cups. These cups are mounted on horizontal arms that extend from the axis of rotation. When using it, make sure that each cup is pointed in the same direction with its face perpendicular to the floor.

- Sturdy structure and good stability.
- A smooth Gear-driven model.
- Manually movable moon.
- Shadow hemisphere to represent night.
- Includes a detailed instruction manual.
How many days does it take the Earth to revolve around the Sun? The answer to this question and more are answered when using this gear-driven model representing the Sun, Moon and Earth and their relationships. Daylight, night, seasons, and phases of the Moon are all effectively demonstrated. Arm is 15″ long; Sun is 6″ in diameter; Earth is 4″ in diameter; moon is 1″ in diameter.
ILLUMINATED ORBITER
- Made of superior quality polymers
- A smooth Gear-driven model.
- Mounted on a sturdy base, labeled with each month of the year.
- Includes a detailed instruction manual.
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. Arm is 15″, Sun is 6″ and the Earth is 4″ in diameter. Includes Lesson Plan which includes basic investigations and activities on Day and Night, The Seasons, The Moon, plus Observations and Activities.

Celestial Star Globe
Study the stars with your own planetarium!
- Globe-IN-Globe configuration. A Celestial star globe made of Superior quality polymers.
- Easy to demonstrate the Earth’s apparent relationship to the Stars, Planets & Galaxies.
- A Perfect medium to define star activities to the Students.
- Mounted in full horizon and meridian base for stability. (B19018T)
- Outer surface can be marked & cleaned. Easily Washable.
- Internal Earth globe is independently movable.
- The horizon is depicted.
- Easy to adjust hour & date settings.
- Ecliptic, ascension and declination scales are clearly marked.
- Includes detailed activity and study guides.
This unique 12″ diameter star globe and 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.
