• the magnet will draw certain metal objects out of the trash

• the magnet will cause the metal cans to move to the side

• The magnet will flatten and recycle the cans while they are being collected

What could the student do to demonstrate an unbalanced forces affect the motion on the soccer ball

• The student could observe and describe the object sitting still. This would demonstrate unbalanced forces.

• The student could push the object from every side. The object would not move but pushes always demonstrate unbalanced forces.

• The student could kick the object from all sides of the box evenly. The object ould stay still but because it is being pushed in several directions, this would demonstrate unbalanced forces. 

• The student could kick from the one direction. The kick would push on the ball. When the ball slides on the field, the motion would demonstrate unbalanced forces.
