Spoilers are small control surfaces that pop up into the air stream to help “spoil” lift or create additional drag on the wing surface. Aircraft often have spoilers in their design to help in a turn by increasing the drag over one wing.

On landing you can watch the spoilers pop up on the trailing edge (back of wing) which helps slow the aircraft on the runway.
