On my last morning in Porto I was off to a boat tour of the six Porto bridges. I searched for an in depth tour and this boat tour was the best to be found. We cruised up the Douro River, then back down towards the ocean. Of the six bridges in Porto, two bear striking resemblance to the Eiffel Tower in Paris. It was not surprising to find that one of the bridges was designed by Eiffel himself, and the other by his protégé. I was able to take wonderful photographs and video from numerous vantage points to use with the students. Both of these bridges have triangles, rectangles, trapezoids, and rectangular prisms that we will be able to pick apart for calculations. Unfortunately the informational piece of the tour was very general and not interactive. A positive point is that the tour was given in several languages and will be great for my students to listen to as we view the recordings of the bridges.
The rest of the day was spent in the more mundane aspects of traveling as we were will be back in Spain tomorrow.
