In an introduction to weathering, 4C students got an
opportunity to be the primary cause of physical weathering through abrasion.
Students received two types of rocks: conglomerate and granite. The students
made observations and gave descriptions of the rocks. They even got to form a
hypothesis about the effects of the weathering on each type of rock.
Once the
observations and hypotheses were made, the students put each type of rock in a
container to shake, shake, shake. They took turns shaking the rocks for five
minutes.
After five long (and loud) minutes, they got to open up the
containers to observe the results.
In this experiment, students found that conglomerate rocks
weathered faster than granite rocks.
I love these pics!! They are so engaged!
