Yesterday, Mr. Musselman, from the Burlington Science Center, visited Fox Hill 4th graders to lead a "stream table demonstration" as part of our "Earth's Changing Surface" science unit. During the hour-long hands-on activity, students recreated models of river systems in tabletop experiments. The demonstration advanced students’ understanding of how rivers shape the Earth’s surface, while explicitly providing kids with opportunities to develop their scientific practices such as observation, modeling, and experimentation. Students gained knowledge that the angle and amount of water flow affect the shape of a river and observed the surface features that resulted. Following are some photos of our Room 20 scientists "in action" at the stream table activity. Enjoy!
