President Barack Obama hosted the annual White House Science Fair.
It aims to highlight all the hard work by American students in Science, Technology, Engineering and Math.
The President commended the students on their projects, which ranged from infectious disease research to a new kind of reusable sandbag to prevent flooding.
"I want to make sure that every young people across America knows what their peers are doing to inspire even more work in science. That's what this White House Science Fair is all about," Obama said.
The president also unveiled a new $35 million teacher training program as part of his goal to train 100,000 educators in the STEM fields.
