Richard solved his lion problem, not once, but three times.  Each iteration or each solution he developed was better than the last. 

In this video, Richard teaches us that using iterative design not only produces solutions, but he showed us that iterative design is a continuous loop of improving the solutions to his problem.

According to Tom Wujec of the Marshmallow Challenge, teams can collaborate on solving problems using a loop between prototype (creating a solution) and refine (making the solution better). 

Also, Richard showed extreme resourcefulness in his use of recycled materials. Imagine if more products were designed to ensure they can be recycled and used again.

By designing, re-designing and re-designing again, Richard was not only able to improve his solution for the lions, but he was able to improve his life as well as his family's life. What could you design to improve your life or the lives of others?
We live in an engineered world. Nearly everything around us, from our toothbrushes to our shoes to the transportation systems we take to school everyday, is a result of iterative design. The best designs solve critical problems and improve our everyday lives. Take another look at how students like you can create amazing solutions...
