Document Content and Description Below

Student Exploration: Convection Cells Vocabulary: convection, convection cell, density, global conveyor belt, mantle, mid-ocean ridge, subduction zone, vector, viscosity Prior Knowledge Questions (... Do these BEFORE using the Gizmo.) You place a pot of soup on the stove. As the soup warms you notice some areas where soup is rising up and other areas where soup is sinking down. 1. Why do you think some of the soup is rising up? It has the highest temperature. 2. Why do you think some of the soup is sinking down? The effects of boiling. Gizmo Warm-up When fluids (gases or liquids) are heated, they tend to move. This motion is called convection. In the Convection Cells Gizmo, you will observe and experiment with convection both in a laboratory setting and in several real-world examples. To begin, note the laboratory setup on the MODEL tab. A beaker of liquid is placed above a gas burner. Click Play ( ). The burner is now heating the fluid. 1. What do you notice? It is moving in a circle. 2. Drag the eyedropper into the beaker just above the burner and let go to release a drop of orange liquid into the beaker. What do you notice about the path of the drop? It floats up and down in a circular motion. Activity A: Convection Get the Gizmo ready:  Click Reset ( ), and set Burner A to High. Question: What causes convection cells to form? [Show More]
