Flickinger second graders are learning how water shapes the earth’s surface.
In this lesson called, “Why is there sand at the beach?” they learned how rivers can be powerful enough to carry rocks and slam them into each other, breaking them into smaller and smaller pieces along the way.
" I learned that when the rocks came down the mountain they break into smaller and smaller pieces." Makayla Kashat.
Marlecia Moshe added: "During this experiment I saw erosion happening because of the movement of the rocks."
From the results of their investigation, students constructed an explanation for why there is sand at a beach.
"I learned that the water and the rocks collide and crush apart to make sand,” said Travis Diehl
