Pam Mills brings science to Keller Library's summer reading program

Mary Forman helps Pam Mills measure water for one of the demonstrations during the program.

Isabel Ramsey helps Mills count pennies as she drops them in  a glass of water. The goal was see how many pennies it would take overflow a glass of water filled to the brim.

Mills pours colored water into a container of salt water to show how they separate due to the density of the salt water. Children's librarian Chris Hillis holds the microphone for Mills.

The container of colored water and salt water at the conclusion of the experiment. A golf ball floats in the middle of the container on top of the salt water.

Mills displayed three fossils from the university for the kids to examine. They are all from a Triceratops. From top the smallest of the three horns that were on a Triceratops, a vertebrae and a piece of the frill (the bony structure behind the Triceratops head).

Some of the kids in attendance get to hold and examine the fossils with Mill's assistance.
