Military Museum Revisted

Last year, I took my 5th and 6th grade class to the military museum. We endured a 2+ hour tour (on our feet the entire time). My class did a great job! I was feeling completely overwhelmed with the amount of information but they kept asking questions and listening well.
When it came to planning this year's field trip, I knew that neither my 4th or 5th graders had been to the military museum so I thought it would be a great idea to go again. I asked our secretary to call and make the appointment and to please clarify that we were hoping our tour would be no longer than an hour. I also checked with the history teacher to get an idea of what time periods my students were studying so that the tour guide would be able to focus on that period. The idea was great, but didn't so much work out in reality. 1 hours into the trek through the museum, the guide informed me that the only way out was through the rest of the museum but that she'd try to hurry. 30 min later, feet sore and minds exhausted, we exited the museum and found ourselves in the courtyard filled with tanks and other military vehicles. My students enjoyed running around the fresh air and then sitting to give their feet a break before trekking back to school.
