我的七年级美术课通过本次“棉花糖与圆柱体”静物素描，学习了基础构图技巧及观察能力素描技巧。
本教案由米歇尔·C·伊斯特（Michelle C. East）撰写 © 2017年，灵感源自法塔老师关于明度与形体的课程
教学目标：
- 学习观察线条“弯曲程度”的观察能力素描技法；
- 学习以肩部与肘部带动的流畅动作绘制直线、圆形与椭圆；
- 将椭圆知识、视点概念及线条角度知识运用于小幅静物素描中；
- 学习在黑色卡纸上运用白色炭笔的炭笔技法，并以完整明暗/排线完成画面表现。
- 弯曲程度： 观察线条弯曲的程度。注意物体视点变化时，线条弯曲程度随之改变。留意杯子上椭圆轮廓及底部边缘线如何随视点变化而变化。当物体的视点发生变化时，圆形会转变为椭圆。 若我们垂直俯视一个圆柱体（如棉花糖），所见为完整的圆形；当我们向一侧降低视线高度时，开口逐渐变为越来越扁的椭圆，直至完全看不到圆柱体内侧；在视平线上，该椭圆则呈现为一条直线。
a. 课堂活动： 练习绘制圆形与椭圆；练习在不同视平线高度下绘制椭圆。
- 圆柱体与圆柱形物体的绘制： 绘制圆柱体时，先画出中心线（轴线），再以合适角度画出与中心线垂直的椭圆；接着画出连接椭圆两侧边缘向下延伸的侧边线，使其与轴线保持等距；若需更易画出直线，可旋转画纸；最后添加底部弧线。教师示范
a. 速写本活动： 练习绘制圆柱体与棉花糖
项目：黑色卡纸上用白色炭笔绘制棉花糖
项目目标： 运用5–7个聚苯乙烯泡沫塑料杯（两种尺寸）设计富有趣味性的构图；准确运用椭圆知识、视点概念及线条角度知识完成静物素描；结合白色与黑色炭笔技法，以完整明暗/排线完成画面表现。
所需材料： 白色炭笔、斯特拉特莫尔400系列阿塔盖恩画纸·煤黑色·12″×18″、卷笔擦（擦笔）、可塑橡皮
操作步骤：
- 选取5–7个棉花糖与木质圆柱体，组合成富有趣味性的构图；
- 在黑色素描纸上用铅笔或白色炭笔轻淡地、尽可能准确地勾勒出构图轮廓。
- 使用白色炭笔以完整明暗/排线完成画面表现。

My 7th grade art class learned basic compositional skills as well as drawing observational skills with this Marshmallow & cylinder still life drawing.
This lesson plan was written by Michelle C. East © 2017, Inspired by** Mr. Fatta’s Lesson on Value & Form
Objectives:
- The will learn the observational drawing technique of observing the “Degrees of Curvature” of line.
- They will learn to draw lines, circles and ellipses by using fluid motion of swinging from the shoulder and elbow.
- They will apply knowledge of ellipses, point of view, and angles of line and apply it to a small still life drawing.
- Students will learn charcoal techniques drawing on black paper with white charcoal and render the drawings with full shading.
- Degrees of Curvature: observing how much a line curves. Observe how the curvature of a line changes with your point of view of an object. Notice how the ellipses as well as the bottom lines on the cups change as the point of view changes. Circles change into ellipses when our point of view of the object changes. If we look directly down at a cylinder, like a marshmallow, we will see a full circle. As we lower our position to one side, the opening becomes more & more of an ellipse until we cannot see inside the cylinder any longer. At eye level, the ellipse appears to be a straight line. a. Activity: practice drawing circles & ellipses. Practice drawing ellipses at different eye levels.
- Drawing Cylinders & Cylindrical Objects: To draw a cylinder, start with center line or axis. Then draw the ellipse at the right angles to the center line. Draw side lines connecting the edges of the ellipse down toward the bottom so they are equal distance from the axis line. Turn your paper if it makes it easier to draw the straight lines. finally add a curved line at the bottom. DEMO
a. Sketchbook Activity: practice drawing cylinders and marshmallows
Project: Marshmallow White Charcoal Drawing on Black Paper
Project Objective: Create an interesting composition of 5-7 Styrofoam cups using two different size cups. Apply knowledge of ellipses, point of view, and angles of line to accurately draw the still life drawing. Use white and black charcoal techniques and render the drawings with full shading.
Supplies: White Charcoal Pencils, Strathmore 400 Series Artagain Pad, Coal Black, 12″x18″, Tortillions, Kneaded Erasers
Instructions:
- Choose 5-7 marshmallows and wood cylinders to arrange an interesting composition.
- LIGHTLY draw the composition onto black drawing paper as accurately as possible (in pencil or white charcoal pencil).
- Use white charcoal pencils to render the drawings with full shading.
