While at the museum they checked out each of the exhibits. It was National Chemistry Week so the American Chemistry Society hosted a chemistry fair. They learned about, sugar content in foods, how soap works and how to use litmus paper to determine the Ph of chapstick...and Larry is a lifetime member of the society so he was a proud Dad watching his babies learn about chemistry. They thoroughly enjoyed each exhibit. Abigail loved organizing the animals and Olivia had a great time learning about shadows.
