A GRANDE — Kids can learn

Memorial Library, 2006 Fourth St.,

This event, called “Chemists
Celebrate Earth Week,” is pro-

chemistry professor.
“It is designed to communicate
the positive role that chemistry

The EOU Chemistry Club will provide hands-on activities on Friday, April 22, at Cook Memorial Library in La Grande. The theme is “The Buzz About Bugs: Insect
Chemistry.”
“We will provide hands-on
activities for children,” she said.
Youth must be accompanied
by an adult.
The club will set up three
stations. At one, kids will make
a natural dye using Cochineal
insects, which Cavinato said are
used to color food, beverages
and cosmetics.
“We will observe how the
color changes when we mix it
with safe household products of
varying pH,” she said.
Another station will have
participants pretend to be bugs
and identify common aromas
from natural fruits, fl owers and
products that use scents as part
of their ingredients.
The third station will feature
Dr. Laura Mahrt from the EOU bi-
ology department with displays
of bugs from all over the world.
