A new spinal implant, an automated page turner and a more efficient way to make energy from algae. Those are among the projects that young scientists shared with President Barack Obama at the White House Science Fair on Monday.

“I want to thank you for inspiring me,” Obama said in remarks at the science fair. “Keep exploring. Keep dreaming. Keep asking why. Don’t settle for what you already know. Never stop believing in the power of your ideas, your imagination, your hard work to change the world. “

The president gave special notice to a group of 6-year-old Girl Scouts from Tulsa, Oklahoma, the youngest scientists of the day, who built a page-turning device out of Legos to help individuals who are paralyzed or have arthritis. He said the “Supergirls” stressed to him that the device is just a prototype.
