Liquid Crystals:
A Fourth State of Matter
Combine two clear liquids and heat them, then
watch as the mixture produces vivid color changes from red to green to blue as it
cools. From skin mapping to circuit board testing to mood rings, liquid crystals have
amazing modern applications. Liquid crystals have properties hovering between
solids and liquids—molecules move independently as in a liquid, but they tend to
orient or align themselves like a crystalline solid. The alignment of the molecules
changes with temperature to produce fascinating color changes. A simple introduction
to nanotechnology!
Complete for 8 groups of students working in groups of 3 or 4.

Modeling Nanotechnology—
Encapsulation by Sodium
Alginate—Student
Laboratory Kit
By: Brett Criswell, Central Columbia H.S., Bloomsburg, PA
An exciting new breakthrough in nanotechnology involves the delivery and transport
of medicines to treatment areas in the body by encapsulating drugs in molecular
“cages” consisting of nanoparticles. In this modern, hands-on lab activity, students
will model this technology on a larger scale using sodium alginate, a natural polymer
from seaweed. When sodium alginate is added to a solution containing calcium ions,
calcium alginate precipitates out as micro-spheres. These “capsules” can be used
to trap and also release indicator dye molecules. An engaging modern-chemistry
experiment!
Complete for 30 students working in pairs. Reusable 6-well reaction plates are
recommended and available separately.

You rock! I want to continue buying our chemistry products from Flinn because
they come quickly and the order is correct. Thank you for making
it easy for me. :)
