Check out the Main Street Marble Machine Company (aka Mrs. Angela Johnson's mixed 1st and 2nd grade class)!
The entire class worked together to build a machine that moved a marble from one end of the classroom all the way out the door to the hallway.
One student described the project perfectly, "This is really hard, but really fun!"
Students learned critical thinking, problem solving and collaboration skills. They also discussed engineering and physics concepts like force, friction and ramps.
