Gretchen Schmaltz is the science education manager for the Children's Museum of Houston and Kendra Rodriguez is one of their Resident geeks with a PhD. They're presenting the new Flint Hills Resources Genius Station. It's basically a moving station that shows up in front of the museum's awesome exhibits. It allows kids (and grown-ups) to ask questions from real scientists.
The museum has so many great exhibits it's impossible to see everything in one visit so check out their website for more info and take advantage of their big discount for memberships until the end of May.
