Easy Hydraulic or Pneumatic Machine - Engineering Projects for Kids

Be sure to check out https://www.STEM-Inventions.com/ for more projects like this! The STEM Inventions series is a collection of STEM Projects that I developed while teaching K-6 students. Every project uses the same set of inexpensive materials so it's cost effective for parents and educators to do multiple projects or teach large groups. Printable lesson plans and project picture sheets are available at https://www.stem-inventions.com Hydraulic Machine: This is the easiest hydraulic-powered machine to build, and the project idea process is straightforward: create a hydraulic-powered hinge, and then customize its function. And of course, learn about the science and engineering behind hydraulic power!
