6) Expose them to mentors with science degrees. Show them at an early age what an actual scientist or engineer does. Evans talked about bridges with her students. Then she allowed the kids to design bridges using Popsicle sticks. They applied weight to the bridges to see which ones hold the most weight. Later they explained that this is what a civil or mechanical engineer does. Then they had actual construction people come in so that the kids could understand who designs and develops a bridge. This shows them future job options.
