The term 'They Have Their Ups and Downs' can be described by four different words: SEESAWS (7 letters), Steps (5 letters), Yoyos (5 letters), TeeterTotters (13 letters), and Rollercoasters (14 letters). SEESAWS are two-person play equipment that consists of a board balanced on a fulcrum, with each person sitting on either end. Steps are a series of flat surfaces that allow people to move from one level to another. Yoyos are toys consisting of an axle connected to two disks, and a string looped around the axle. TeeterTotters are similar to SEESAWS, but they are designed for more than two people. Finally, Rollercoasters are amusement park rides that consist of a track with steep drops and sharp turns.
