2nd Grade: Wind Machines

Second graders recently completed their unit called Air & Weather. Their design challenge for this unit was to create a machine that could use the wind to move.  Students conducted many experiments to learn how to capture and use wind. Then they chose if their machine would move on land, water, or in the air.  After planning and prototyping, each group tested their machine and reflected on how well their prototype worked.  Each group learned about prototyping materials and what it takes to make a functioning prototype.
