註釋The first time the term “tractor beam” was used was in 1931. Since then, tractor beams have been used in many science fiction books, movies, and TV shows to draw in spacecraft, people, and objects in space. This science fiction technology has become science fact. In 2015, scientists used sound waves to move tiny objects. Through reading about this and other modern technology, readers are engaged with incredible STEM information as well as their imaginations as they also learn the connections between this technology and popular science fiction.
