YES teens work at Missouri Botanical Garden's Earth Day Celebration

City Science YES teens worked with over 75 kids and their families at the Missouri Botanical Garden's Earth Day celebration.  Teens demonstrated wind power and solar power by making windmills and solar powered sketch robots with visitors.  Teens explained to kids and their families how solar panels work and why they are better for the environment.  It was a great way for teens to conclude this semester, and gave them a chance to disseminate their STEM knowledge to other youth!  Way to go City Science YES teens!
