Campbellsville Middle School students are learning all about cells.

In Amy Knifley’s science classes, students are learning about cell structure and function.

Students have also studied the tissues, organs and organ systems that make up the human body.

After completing a thorough review for two class periods, students took an exam to test their knowledge.
