In this SciShow Kids video, Squeaks and the host explore the concept of simple machines, focusing on levers. They attempt to lift rocks to find insects, using a lever to make the task easier. The video explains how levers work, using a seesaw as an example, and demonstrates how changing the fulcrum's position affects the effort needed. Everyday examples of levers, like wheelbarrows and bottle openers, are discussed. The video concludes with an invitation for viewers to ask questions about machines or insects.
