RUBBINGS
|
|
The rubbing
technique reveals textures and patterns that are not readily
visible. Students make rubbings of leaves to observe and compare
venation patterns. They look for patterns and hidden messages
in a variety of other materials and invent games and organizing
systems based on rubbings. |
•
Texture refers to the surface features of a material.
• Pattern is a design or arrangement of objects.
• Veins transport materials in a leaf.
• Leaf-venation patterns can be organized into three types:
parallel, palmate, and pinnate. |
•
Observe rubbings of textured objects.
• Record properties of textured objects using rubbing.
• Compare venation patterns in leaves.
• Sort patterns.
• Communicate observations.
• Invent new ways to use a technique. |

CARBON
PRINTING |
|
Students
use the carbon-printing technique to reveal the fine structure
of textured objects. They make and compare prints of their fingers
to reveal the finger patterns of whorl, arch, and loop. Students
use the carbon-printing technique in creative and inventive
ways. |
•
Carbon printing is a technique used to make fine textures visible.
• Fingerprints can be sorted into three groups based on
pattern: whorl, arch, and loop.
• No two people have the same fingerprints. |
•
Observe patterns made using the carbonprinting technique.
• Record data.
• Compare fingerprints.
• Sort patterns.
• Invent new ways to use a technique. |
|
3. |
COLOR
WRITING |
|
Students
use the technique of paper chromatography to investigate hidden
pigments in water-soluble ink. After observing pigment separation,
students invent applications for this process and share their
ideas and products with the class. |
•
Chromatography uses water to carry pigments from one place to
another.
• Paper chromatography reveals pigments in watercolor
inks.
• The process of water moving through paper is called
wicking. |
•
Observe wicking and the separation of pigments in ink pens.
• Record data.
• Compare prints made by pigments.
• Communicate observations.
• Invent new ways to use a technique. |

REFLECTING |
|
Students
explore mirrors to see things that they don't normally see—their
eyes and activities going on behind them. Students explore mirror
images, including reversals and lines of symmetry in objects.
They investigate how to reflect images from one mirror to another
and assemble a periscope. Finally, they use mirrors to be inventive. |
•
Light travels in straight lines.
• Symmetry is an arrangement in which the parts on opposite
sides of a center line are the same.
• Mirror images are the result of light reflected from
a surface.
• An image produced by something that reflects, such as
a mirror, is always reversed right to left.
• Mirrors can be used to determine symmetry in objects. |
•
Observe things in and about the environment that are not easily
seen.
• Use mirrors to manipulate light and images.
• Compare objects using symmetry as a property.
• Invent ways to use mirrors to produce useful or aesthetically
pleasing products. |
