Value Extension- Value Scale

I was so incredibly impressed by the 2nd graders this week. They created what is called a value scale using pencil and 1 single color. My friends who teach in the High-school level told me that their 9TH GRADERS have a problem with this! Well, our 2nd graders got this without me even repeating a word! As a page in their sketchbooks, the students were given a value scale sheet. After a demonstration with a light, a cube, a cone and a sphere to show that when light hits something directly, it actually changes the color of the object it is projected on. They first took a pencil and shaded a gradient chart from dark to light and then picked one crayon color to do the same. The students learned that you can change a color just by adding or taking away pressure to the pencil or crayon. On the bottom of this sheet was a cone, a sphere and a cube that they had to shade in with pencil or a crayon as well. Value, which is one of the principals of design, is used in art to create a 3D look to something that of course is 2D. It creates an illusion that an object has volume and isn't flat. 

Learning Objective: Value, value scale, shading from dark to light

ART WORDS:
Value: The lightness or darkness of tones or colors. White is the lightest value; black is the darkest. The value halfway between these extremes is called middle gray. 
light source: the sun, a light in a room, a lamp etc. 
shading: the process used in drawing for depicting levels of darkness on paper by pressing harder for a darker shade for darker areas, and less pressure for a lighter shade for lighter areas.
value scale: A scale or gradient that shows the change of a color from dark to light or light to dark.
