We love simple machines
Simple machines are everywhere and we use them everyday. They’re so much a part of our lives that we don’t always recognize them. But once you start thinking about them, it’s hard not to see them — everywhere, everyday!
Above, Youngna used a screwdriver — a wheel and axle — to take apart bookshelves before moving. Here are a few more examples we’ve noticed lately.
Stairs are inclined planes.
“On a recent vacation to Barcelona, I was grateful for every staircase I found. Barcelona can get pretty hilly. Stairs can make the climb a bit longer—but easier!”

Scissors are made up of levers and wedges.
“I collect scissors. The big scissors cut through plastic packaging, while the little ones are perfect for cutting herbs from my window garden.”

Pulleys!
“My favorite weekend activity is sailing. Pulleys are used to adjust and tighten the boat’s sails.”

A rolling pin is a wheel and axle.
“I use a rolling pin to make pierogis.”

Raul’s kids use an inclined plane to travel up and down (quickly!).
