Product Description

The measuring equipment of the sun height

Product Introduction
The earth's four hour movement and the alternation of day and night are closely related to the sun. In 365 days of a year, at the same time and at the same place, the sun's position is also different. The sundial invented by the ancients with this rule is a tool that uses the sun's projection to indicate time, to reflect the four seasons, temperature, phenology, etc., and to calculate the 24 solar terms of a year.

The measuring equipment of the sun height also adopts the principle of solar projection: it can measure the height illumination angle and real-time azimuth of the sun, and also can measure the length of the solar projection.

Product Specification

Product name	The measuring equipment of the sun height
Structure	The instrument consists of chassis, angle plate, bracket, compass, pole, etc
Material	Plastic
Size	Φ135x165mm

Instructions
1. Measure the solar height by projection method
Place the instrument on the horizontal ground under the sun, and rotate the angle dial to make the solar spot passing through the projection hole project on the center of the screen. At this time, the scale indicated by the angle dial pointer is the current solar height angle.
2. Explain the causes of the four seasons (for students' extracurricular activities).
Place the instrument on the horizontal ground under the sun, rotate the chassis so that the "00" indicator is aligned with the due south direction, then rotate the angle disk bracket horizontally to make the angle disk plane parallel to the sun light, and then rotate the angle disk longitudinally so that the sun spot passing through the projection hole projects on the center of the screen. At this time, the pointer value of the angle disk is the sun height angle, and the pointer value of the chassis is the sun azimuth angle. This method is used to measure the solar altitude angle and chassis azimuth at noon on the four solar terms of the year, namely, the vernal equinox, the summer solstice, the autumnal equinox and the winter solstice, and record the observation results
3. Measure the shadow of the pole under the sun
Pull the angle plate and bracket out of the chassis and replace them with upright poles, place the instrument on the level ground under the sun, and rotate the chassis so that the "00" indicator is aligned with the south direction, Read the azimuth angle and length of the shadow through the angle ruler and length ruler on the chassis (to measure the length of the shadow more accurately, after reading the azimuth angle of the shadow, rotate the chassis to make the shadow coincide with the length ruler, so that the measured length is more accurate).
Select several time points in a day, measure the shadow length and azimuth of each time point according to the above method and fill in the table.

To get the height of the sun, draw a horizontal line segment equal to the shadow on the blank paper, then draw a line segment equal to the exposed part of the pole from one end of the line segment, and connect the other two ends of the two line segments to form a diagonal line. The angle between the diagonal line and the horizontal line is the angle of the sun height, which can be measured by the student protractor.

Product feature and application
For primary school science teaching to measure solar height.

Maintenance and precautions
1. The instrument shall be stored in a cool and dry place when not in use. The instrument will be deformed or damaged when heated, pressed or dropped.
2. The stain on the surface of the instrument can be cleaned with a towel dipped in neutral detergent, and organic solvent or hard materials cannot be used for decontamination.
