Query: Particle Physics Outreach to K-12 Schools and Opportunities in
  Undergraduate Education   To develop an increase in societal interest in the fundamental sciences of
particle physics and particularly for maintaining the support structures needed
to succeed in experiments that take several decades to develop and complete,
requires strong educational back-grounding at all levels of the instructional
system and notably at early stages in the process. While many (particularly
young) students might show an early interest and aptitude for science and
mathematics at the elementary level, the structures are not necessarily in
place to capture, nurture and develop such nascent interests. To encourage and
strengthen such interests, strong connections must be made at K-12 and
Undergraduate levels. The paper discusses the on-going efforts and makes
recommendations.
