Three organizations that emphasize science, technology, engineering and math (STEM) are teaming up to offer the Iowa STEM Pass, which encourages families to explore STEM across the state. Funded through a grant provided by GreenState Credit Union, a ticket booklet will be offered by the Science Center of Iowa, Blank Park Zoo and the Iowa Children’s Museum that features single-use passes for admission to all three organizations, plus discounts on food, gifts and other activities.The Iowa STEM Pass will cost $30 for adults and $20 for children, which represents a significant savings off regular admission prices if purchased individually. The Iowa STEM Pass can be purchased at the box office of all three organizations.
