Children's Museum Tucson, 200 S. Sixth Ave., has brought back Science Sundays, which means admission is only $2.
It also means there will be special STEM (Science, Technology, Engineering and Mathematics) activities all day long. Kids can participate in hands-on demonstrations and experiments in aerospace and environmental sciences, astronomy, biology, ecology, engineering and physics.
Hours for the museum are 10 a.m. to 5 p.m.
