Since you are specifically in need of light lessons for
in-school
and
2nd graders
 
try a web search using the  terms             2nd grade light lessons or 
curriculum or activities
here is one result
_http://www.instructorweb.com/lesson/light.asp_ 
(http://www.instructorweb.com/lesson/light.asp) 
 
be sure what you design fits the local school requirements --- your  state 
curriculum guides maybe online
or ask the state dept of ed for a copy via email? Ask to see a copy  of the 
appropriate text book?
Perhaps ask a 2nd grade teacher/   or the district  curriculum coordinator?   
or science dept head?
Always go through the Superintendent and principals to arrange school  
contacts,.
 
Maybe also ask the elem school librarians? --- what equip do  they have on 
the topic?  Media or?
 
Best wishes, Barbara Hass, retired librarian (K -  12)
