【正文】 d to figure out these things earned him the top prize at the 2021 Broad MASTERS． MASTERS stands for Math， Applied Science， Technology and Engineering for Rising Stars． Every year， the event brings together 30 middle school students from around the country to share their science projects． “ At first， I thought that my ideas were naive，” the teenager told Student Science．“ But when I was presented with this special award， it proved that young inventors can actually deal with realworld problems．” Inspired by reports of the Deepwater Horizon oil spill in the Gulf of Mexico， he connected washing dishes to cleaning oil spills．“ I decided that I wanted to find a method for cleaning that’s both efficient and environmentally friendly，” Nathan told Student Science． So he created his own setup for measuring surface tension— a scientific term that refers to the tension of a layer of liquid． He ended up learning why soap and hot water are better for cleaning， and a way to remove oil from water. “ Science and math help you understand the world around you． You can learn it from books and teachers， but you can also discover it yourself by doing science projects．” He even plans to sell his setup to schools， so other teens can do his experiment and learn his theory． When asked his secret to success， he said to keep a science fair project simple at first．“ Break down the problem into smaller， manageable steps， so in that way， you will be able to know what you doing and build on your knowledge gradually．” 21． What do we know about Nathan?
