Thank goodness the field trip to the Tellus Science Museum was inside! If you haven't been I'd highly recommend it. They do a wonderful job! Our 5th graders were even complimented on their outstanding behavior by some of the museum workers. :)

Now count the number of yellow tiles near the swinging pendulum. How many are still standing? This picture was taken 2 hours later from the one earlier.
