Product description:
To understand the basic part of the telescope.
To understand the double lens is how reflection imaging.
Understand the refraction, reflection, catadioptric telescope structure.
To understand the history of the telescope; to understand the basic structure of the telescope; to understand the simple principle of telescope.
The objective and the eyepiece of the telescope optical axis coincidence, the adjacent lateral coincident focus on apoint. Two times zoom lens distance AB to distant objects is much larger than the lens, convex lens by imaging lawknowledge, AB like A'B'to objective incentive is slightly larger than the focal length of the lens, the distance to theeyepiece is slightly less than the focal length of the lens. So through the eyepiece will see A'B'- like.

The children finish assembly process parents with children learning situation, heuristic education.
To explore the boy is exploration, he is not a simple science, but involves a variety of subjects, such as physics,chemistry, astronomy, mathematics, and its visualization, modeling, standardization. Objective is to commence from the interest, find the children's interest in learning, so as to effectively guide, finally let the children interested inlearning. To feel the real world with the scientific thought of splendid, the virtual world and let the children stay away from computer games.
