During a video conference with the Fort Worth Museum of Science and History in Texas, Shore Road fifth-graders learned to think like scientists in order to make a robot draw. The activity fell in line with the district’s science, technology, engineering, arts and mathematics curriculum with students ordered to complete three engineering tasks dealing with open, closed and off set motor circuits. The result was a robot, called a scribblebot, that moved along a sheet of paper and which scribbled colorful designs.

After a discussion about the engineering design process, students learned to make closed and open circuits using a battery, battery clip, motor and two alligator clips. During the second challenge and the addition of rubber bands and a glue stick, they engineered a motor to make a cup move. The final challenge and addition of different-sized markers resulted in the design of a scribblebot.
