I took my 4 and 6 yo daughters to IDEA today. They spent the entire day there, a couple hours in the child play area, then several hours learning about bugs in the bug exhibit. The museum definitely kept their interest; from making a farm garden plot in the play area, creating crafts, doing the "bee wriggle dance" in bee costumes, putting on a bug themed puppet show, to looking at a slew of preserved bug specimens, the museum offered much more than we could have anticipated. We would not hesitate to go again and will be recommending IDEA to all of our friends with kids.
