Directions: Each group of students was given three different rock samples. They were asked to identify as many properties as they could.
Student Sample #1
This sample had texture, color, and crystal content. That's about three of a possible six ways the student could have described the rock. I would consider this meeting the standard.
Student Sample #2
This student sample has between five and six properties of the rocks- hardness (scratch mark), color, texture, crystal size, luster, and cleavage. I would consider this standard setting for a third grader. (Above standard).
Student Sample #3
This student sample has between four and five properties. The only obvious property missing is the size of the crystals. I would consider this standard setting, though not necessarily superior.
The following are pictures of the students taken during the rock properties lesson.
Examining the crystal size!
