献给你的帖子：石膏上的埃及神祇

一篇致敬其他优秀教师教学成果的帖子！今天，我们分享佛罗伦萨卡尔曼德雷伊中学与皮兰德娄中学初中部美术教师亚历山德拉·托姆贝西（Alessandra Tombesi）的教学实践。亚历山德拉为六年级学生（或小学其他年级学习古埃及主题的学生）设计了一项富有创意的课程任务。

所需材料：
– 塑料盘、石膏粉与砂纸（用于制作圆盘）；
– 透明描图纸、铅笔及刻划石膏用的尖头工具（一支无法书写的圆珠笔亦可）；
– 水彩颜料与清漆（用于着色与上光）。

在学习古埃及文化后，六年级学生从全部可选神祇中自主选择一位埃及神祇。全部15张JPG格式模板（共含27位不同埃及神祇）可在此处下载。

   

学生运用方格缩放法（在5毫米方格纸上按比例缩小原图），用软铅笔将图像描摹至透明描图纸上。

我们用液态石膏灌入塑料盘，制成石膏圆盘。

待石膏表面经砂纸打磨平整后，学生将描图纸上的图像转印至石膏圆盘上。

随后，学生用无墨圆珠笔或削尖的工具在石膏表面刻划图像，并添加装饰纹样、埃及象形文字或符号——这些元素均取材于埃及壁画。

学生用水彩颜料为圆盘上色，调和色彩并尽可能将颜料填入刻出的凹槽中。

待颜料干透后，学生再次刻划部分细节，使白色石膏底色凸显出来。

最后，在表面涂覆一层透明清漆，使色彩呈现光泽感。

A post for you: The Egyptian deities on plaster

A new post dedicated to the work of other excellent teachers! Today we publish the experience of Alessandra Tombesi, an italian Art teacher in the Middle Schools of Calamandrei and Pirandello in Florence. Alessandra offers us an original task suitable for 6th grade classes, or other classes of Primary School, who study the topic of Ancient Egypt.

Materials required:
– Plastic dishes, plaster and sandpaper for the preparation of the disc
– transparent tracing paper, a pencil and a tip to engrave the plaster (even a pen that does not write it’s ok)
– Watercolors and varnish, to color and polish.

After studying ancient Egypt, pupils in classes of 6th grade, they chose an Egyptian deity, among all those available. All 15 templates in JPG, with 27 different Egyptian deities, are downloadable here.

   

Students have scaled down the images using the technique of grid (reduced from the original, on a sheet with squares of 5 mm) and have traced it on tracing paper with a soft pencil

We have made the disks of plaster, putting the liquid plaster into plastic dishes

After you have smoothed the surface of the plaster with sandpaper, students have traced the drawing on the disk.

Afterwards, the students engraved the image, scratching the plaster with a pen without ink or a sharpened tip, enriching it with decorations, Egyptian letters or signs, taken from Egyptian paintings.

With watercolor paints, they colored the disc, blending the colors together and doing as much as possible to deposit the pigment into the grooves etched.

Once the color has dried, the students have engraved again some details to bring out the white plaster.

At the end, the transparent paint coating on the surface, it gave gloss to the colors
