National Aquatics Center - "Water Cube"
China Pavilion at Shanghai World Expo 2010
In order to study chemical substances, scientists create three-dimensional models of substance molecules
All kinds of architecture are inseparable from its prototype - three-dimensional model
Activity
1. Using cardboard as the main material, make the three-dimensional models represented by the two sets of views below.
Topic learning to make three-dimensional model PPT, the fourth part: in-class testing
According to the two sets of views given below, make the corresponding physical model using potatoes (or radishes).
Each set of plane figures below is composed of four equilateral triangles.
(1) Point out which of them can be folded into polyhedrons, trace the above figures on paper, cut them out, fold them into a pile, and verify your answer;
(2) Draw a three-dimensional view of the polyhedron that can be folded from the above figure, and point out how the three views reflect "the length is aligned, the height is equal, and the width is equal";
(3) If the side length of the small triangle in the picture above is 1, what are the volume and surface area of the corresponding polyhedron?
Topic learning to make three-dimensional model PPT, Part 5: Class summary
1. Mathematics is a science whose main research objects are quantitative relationships and spatial forms. Quantitative relationships and spatial forms are abstracted from the real world.
It is obvious that knowledge about projections and views arises from practical needs (architecture, manufacturing, etc.) and they are very closely related to the actual model.
2. Perceptual knowledge needs to be upgraded to rational knowledge, and practice under the guidance of theory will be more clear and effective.
3. In terms of skills, understanding the connection between plane graphics and three-dimensional figures will help to realize the mutual transformation between them as needed, that is, learning to draw three views and drawing three-dimensional figures from three views. In terms of ability, understanding the plane The connection between graphics and three-dimensional graphics is very important for cultivating spatial imagination ability.
