# Grand Challenges K-12 Outreach

The National Academy of Engineering’s Grand Challenges inspire our students and faculty to positively impact others. One way we can do that is through supporting teachers and helping to teach younger students how science, engineering and math can be used to solve some of the world’s toughest problems.
In this section Open Close

## Grand Challenges in the Classroom

The purpose of the Grand Challenges After-School Project is to increase 4th and 5th grade students’ interest in Science, Technology, Engineering and Mathematics (STEM). The strategy used to increase interest is an after-school project developed by students in RH 330 and focused on the National Academy of Engineering’s Grand Challenges for Engineering.

Rose-Hulman student teams prepared a hands-on activity suitable for elementary school students. After feedback from peers, local teachers and Rose-Hulman faculty and staff, the teams completed the documentation of the activities including:

• a one-page proposal
• detailed instructions for the hands-on activity
• supplements (visuals, videos, handouts)
• a teacher’s guide with detailed background information on the specific Grand Challenge chosen and how to prepare for the activity

Cleaning water is a challenge that has largely been met from a technical perspective, yet millions of people lack access to a reliable source of clean water. Combined knowledge of social factors, usability issues and human-centered design will help meet the challenge of providing access to clean water.
