Day! Prepare for the
Pathfinders Hydraulic STEM Engineering Maker Set Make some samples for display!
We suggest you familiarize yourself with the pieces, and, if you make a few simple machines for display - you can learn about the pieces - and have something for the students to experiment with when they arrive. In the manual we suggested that you place the pieces in basins for easy access and it is also a good idea to have a tray of some kind so the kids can get a bunch of pieces, and O-rings and have them handy at their desk. We don’t need to explain how to make the samples in any great detail, they are pretty easy to make, but we have some pictures of simple machines on the following pages. Enjoy! 1
smallest dowels insert into holes - they hold the upright pieces
the linkages are great for easy attaching!
angled pieces make the structure strong! (use the small dowels)
you can use O-rings to hold the dowels - or not bother so it is easy to adjust as you go! 2

demonstrate how moving the dowel changes the range of motion - and note that the syringes can slide in the holder!
