How hands-on learning fires up your brain

To strengthen your mind, work with your hands, says former astronaut Leland Melvin.

  • Learning is a mental and physical pursuit, says retired astronaut Leland Melvin.
  • Recalling his childhood, Melvin explains how working with his dad to turn a $500 bread truck into a family RV camper ultimately made him a better astronaut, able to maneuver the $2-billion dollar Columbus Laboratory out of the payload bay of a shuttle and attach it to the International Space Station.
  • Experiential learning — like hands-on DIY, engineering kits, and Duplo games — wires your brain for problem solving from a young age. It's a leg-up we can all give to the children in our lives.
  • "[W]hen we let [kids] build and create and it's meaningful and it helps them solve a problem, that gets them thinking about how they can be change makers themselves and how they can be scientists and engineers," says Melvin.
