这是如何实现的？
这是科学……
酷炫科学
对流 与 对流循环 描述的是这样一种过程：受热后密度变小的流体（如空气或水）上升，而温度较低、密度较大的流体则下沉，由此形成持续不断的环流，从而传递热量。这一自然现象驱动着地球上的诸多重要过程，例如影响天气模式（如风与风暴）、海洋环流，以及通过地幔对流推动构造板块运动。
对流循环的工作原理
- 加热与膨胀：当流体某一部分被加热时，其粒子运动加快、间距增大，导致密度降低；
- 上升：这种更温暖、密度更低的流体便会上升至表面；
- 冷却与下沉：流体上升过程中逐渐冷却，密度随之再次增大；
- 循环：较冷、密度更大的流体下沉，由此形成持续上升与下降的流体循环，即对流循环。
灯体的多种造型
为你设计的熔岩灯绘制一个外形轮廓。
它应呈对称结构，包含顶部灯盖、底部底座，以及中间的玻璃瓶身。
你想采用哪种配色方案？
光源位于灯底座底部，因此在进行色彩混合与运用明度](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh5sB5syY7GKOOxPIim0C25AJ7eYjXZr6cjbPXmpTGz1w6deJHM5k2tuK0Pbn3n_Md_0Xar5t9arNJIrfIGKGtPhYsn2ySWLMSd3iRPKNRKEltItrXkkjzb5uggokMeh0su_UKPZ2i4cFkuihleaawFOTAeo4QYWydJT-O1uhbqmdzzi0I4q6stwVssBBCG/s375/9bd9abd9f26b7c3844981ccbbe441974.jpg))时需考虑这一点。
独特设计创意
挑战你的创造力，将蜡质熔岩滴转化为具象形状、物体或字母。
每位学生都须通过自主选择
纸张类型与绘画媒介，创造性地解决问题，使自己的构想得以实现。
评分标准：
-灯体造型（25 分）
外形对称，且充分占据画面空间；
完整呈现整盏灯（不可被裁切）。
*提示：可用其他纸张制作模板，沿中线对折以确保对称。
-灯盖与底座的明度表现（25 分）
用轮廓线表现金属顶部与底部的光亮质感；
明确区分深（D）、中（M）、浅（L）三个明度区域。
三维熔融蜡滴（25 分）
- 呈球形、色彩渐变融合，所有蜡滴统一光源（来自灯底）；
- 至少绘制 3 个。
创意背景（25 分）
- 可选思路：色彩渐变、放射状线条、背景中加入熔岩滴、
外太空、静物等。
*灯体在画面中所占面积越大，所需绘制的背景内容就越少。
你可自选绘画媒介——
马克笔、彩铅、蜡笔、水彩、油画棒；
彩色纸或白纸均可。
- 玻璃反光效果（可选）：
玻璃表面因周围灯光照射而呈现白色高光；
若灯周围无照明，则不画此高光。

4 THINGS TO NOTICE:
-Form of lamp is symmetrical
-The cap and base are shiny/metal:
showing highlights with value in correct direction.
-Blobs are 3D-ROUND with lighter area at bottom and darker area on top.
-Sometimes, Glass has a white highlight
Watch it in Action
How does this happen?
It's Science...
GROOVY SCIENCE
Convection and convection currents describe the process where heated, less dense fluids (like air or water, rise, while cooler, denser fluids sink.creating a continuous cycle of circulation that transfers heat. This natural phenomenon drives significant Earth processes, such as weather patterns like wind and storms, ocean circulation, and the movement of tectonic plates through mantle convection.
How Convection Currents Work
- Heating and Expansion: When a part of a fluid is heated, its particles move faster and spread apart, becoming less dense.
- Rising: This warmer, less dense fluid rises to the surface.
- Cooling and Sinking: As the fluid rises, it cools, becoming denser again.
- Cycle: The cooler, denser fluid then sinks, creating a continuous cycle of rising and falling fluid known as a convection current.
Various Forms of Lamp
Create a shape for your lamp.
It should be symmetrical, have a top cap, bottom base, and glass bottle middle.
What color combo do you want to use?
The light comes from the bottom of the lamp base, so consider this when color blending and using value.
UNIQUE DESIGN IDEAS
Challenge your creativity by transforming your wax blobs into shapes, objects, or letters.
Each student must creatively problem solve by choosing
the paper and medium they want to make their idea come to life.
CRITERIA:
-LAMP FORM (25 points)
Symmetrical and filling up space
Show entire lamp (not cut off).
*hint- you can make a stencil from other paper,
folding in the middle to make it symmetrical.
-VALUE ON CAP/BASE (25 points)
Make metal top and bottom appear shiny with contour line.
D, M, and L areas.
3D MELTED WAX BLOBS (25 points)
-Round, color blended, same light source on all (bottom of lamp).
At least 3.
CREATIVE BACKGROUND (25 points)
-Ideas- color blending, radiating lines, blobs in background,
outer space, still life.
*the more space you fill with lamp, the less BG you will have to do.
YOUR CHOICE OF MEDIUMS-
marker, colored pencil, crayon, watercolor, oil pastel.
Colored or white paper.
-SHINE ON GLASS (optional)
-Glass has a white highlight from surrounding lights,
unless the lights around lamp are off.
