一只绝妙的对称昆虫

日常生活中，我们随处可见对称图形——它们既存在于自然界，也见于人类造物之中。本课以昆虫世界为灵感，引导学生创想一种虚构昆虫。在观察各类昆虫及其身体结构（如翅膀、眼睛、足、角、外骨骼等）之后，每位学生自主设计属于自己的昆虫，组合不同部位进行创作。

首先，我们在画纸左侧绘制昆虫的左半边。接着，用一张描图纸覆盖其上，描摹出左半边图形；然后将描图纸翻转至画纸右侧，再用彩铅在描图纸背面反复描画轮廓，使石墨印痕转印到白纸上。此前关于对称的练习也采用过类似方法，例如“自由风格”大写字母与放射对称绘画。

随后，用黑色记号笔勾勒昆虫外形，并选用4–5种颜色的彩铅为其上色。最终，将完成的奇幻昆虫剪下，粘贴于黑卡纸上。

A fantastic symmetric insect

Every day we see symmetrical shapes, that we can find both in nature and in the works of man. We were inspired by the insects’ world, for invent an imaginary insect. After observing various types of insects and their parts, we invented our personal insect, assembling differents parts (wings, eyes, legs, horns, exoskeleton…)

First we drew HALF insect on the LEFT side of the sheet. To draw the other half insect we used a sheet of the tracing paper, and we have traced our drawing. After we flipped the tracing paper on the RIGHT side of the drawing. Subsequently we retraced the design on the back with a colored pencil, so the graphite was imprinted on the white sheet. A similar exercise was done for previous work on symmetry, like the capitals in “free style” and the drawing in radial symmetry.

subsequently, the insect has been drawn with a black marker and colored with colored pencils, choosing a range of 4 / 5 colors. Eventually the fantastic insect was cut out, and was pasted on a black card.
