Summary:
The broken wheel (Wheels): When a wheel falls off Sid's favorite toy truck, he tapes it back on. But now the wheel won't spin, and Sid wonders how exactly wheels work? At school, Sid explores how wheels are simple machines that help move all kinds of things like cars, trains, tricycles, and even toy trucks! My slide (Inclined planes): Sid wonders how he can lift up his big, heavy stuffed animal dinosaur onto his bed. Sid and his friends explore how inclined planes are simple machines that make it much easier to push up heavy things-- including big stuffed animal dinosaurs! Sid's amazing invention (Levers): Sid believes that he has discovered a new invention to put toys away! Sid learns his invention is actually a simple machine called a lever, which is not only useful for launching toys, but can also help lift up really heavy things. The tree house (Pulleys): Sid wonders how he can lift his heavy box of toys way up to his treehouse. After investigating at school, Sid discovers that a pulley is the perfect simple machine to help lift heavy things up to high places, like a tree house!
