説明
Hollow, mesh demonstration globe designed for hands-on teaching and decorative display.
Key benefits
- Clear visual of global coordinates: 24 meridian threads and 9 latitude threads form a hollow, net-like sphere that makes longitude and latitude easy to see and explain.
- Precise, adjustable demonstrations: includes a rotatable Warp-Plane plate and an adjustable latitude pointer so instructors can model seasons, daylight angles, and latitude-dependent phenomena.
- Ready-to-use presentation model: mounted on a stand with the Earth’s axis fixed at 66 degrees 30 minutes to the plane of the base, matching the correct axial tilt for demonstration purposes.
- Versatile gift and display item: compact, attractive, and useful for classrooms, offices, studios, or home learning.
Features and specifications
- Construction: hollow, net-like spherical shell formed by 24 meridian (warp) threads and 9 latitude threads.
- Plates: equipped with a fixed original Warp-Plane plate and an equatorial plane plate for reference and mounting.
- Size: sphere diameter 32 cm; supplied mounted on a stand.
- Axis: Earth axis set at an angle of 66 degrees 30 minutes relative to the plane of the base.
- Demonstration clamp: includes a clamp to demonstrate theoretical time zones and longitude.
- Adjustability: rotatable Warp-Plane plate and latitude pointer; top of the sphere features an adjustment knob to set or lock positions as required for a demonstration.
How it solves problems
- Makes abstract concepts concrete: the open mesh and visible threads let learners trace meridians and latitudes directly, improving comprehension of coordinate systems, day/night cycles, and seasonal changes.
- Saves lesson preparation time: built-in plates, clamp, and adjustment knob allow quick setup of demonstrations without improvised props.
- Durable, visible model for group learning: the 32 cm diameter and mounted design provide good visibility in classroom or meeting-room settings.
Typical use scenarios
- Classroom demonstration: show how Earth’s tilt and rotation create seasons and varying daylight hours by adjusting the Warp-Plane plate and latitude pointer.
- Office or studio display and quick teaching aid: use the clamp to illustrate time zones and longitude relationships during meetings or informal presentations.
- Educational gift: an instructive present for students, teachers, or hobbyists for birthdays, holidays, office openings, or studio decoration.
Operating notes
- Use the top adjustment knob to set the sphere position and lock it for static demonstrations.
- Rotate the Warp-Plane plate and move the latitude pointer to model different latitudes, solar declination, and apparent Sun paths.
- Attach and position the clamp to illustrate theoretical time zones and how longitude lines relate to local time.
This product preserves the original model’s configuration and functions while providing a clear, adjustable, and visually accessible tool for teaching and display.
