In 1962 Penn State University student Ed Kubert completed a science project that compared the properties of minerals and rocks.

In 2015 Tamaqua Elementary School student Jayden Kubert, his grandson, kept pace with the family tradition.The fourth-grader studied the differences between minerals and rocks, and displayed his findings at the school's annual Science Fair."I used either a fingernail, penny or nail to scratch the surface of the material, to see how much it could resist scratching," Kubert said."First I had to gather all the materials I needed, and then I had to write the results of any experiments I did."Kubert was tucked against one of the walls in the school's crowded hallways, as teachers, students and their families strolled around, looking at the various projects.Some projects ranged from the practical, such as which brand of paper towels is most absorbent, what type of fruit makes the most juice or what material makes the best raincoat.Some were factual, such as how many bones are in a cat, or the effects that arthritis has on a body."I wanted to learn how arthritis affects the body," said fourth-grader Basma Bajwa of Hometown."It can really change someone's range of motion."
