Explorit

On my quest for museums in Davis I found Explorit, the only children's museum in Yolo County (*please correct me if I'm wrong*). The first floor has some basic hands-on physics, chemistry and biology experiments. The top floor has a rotating exhibit - the day we went it was "Space", right now it's "Wild Planet". There is an arts and crafts room on the top floor where children can make recycled art. We also attended the daily science demonstration which Big Sis enjoyed.
Overall, not an "out of world" experience but good for entertaining kids older than 4 for a couple of hours.
If we go back, I won't bring Little Bro so I can focus more energy on Big Sis
