Third grade Roanoke Elementary School students recently participated in a rock detective lab where students made a hypothesis on whether each specimen of rock might be igneous, sedimentary or metamorphic.

Students then tested and observed various properties of each specimen, like color, texture, luster, hardness and streak.

Using the information from their testing, students followed a flow chart to identify the kind of rock it was.

Finally, they discussed if their hypothesis was correct and defended their answer by explaining if the rock was igneous, sedimentary or metamorphic and why.
