1. Teacher Guide This lesson is designed to teach kids to ask a critical thinking question that you can’t just put into a search box to solve. To do that, we encourage them with smaller questions that search can help them answer. Make sure that you read the notes for each slide: they not only give you teaching tips but also provide answers and hints so you can help the kids if they are having trouble.

3. In the 1800s, ferry service was the only means of public transportation between San Francisco and the communities of Marin County that lay across San Francisco Bay. As a result, people had been calling for years for a bridge to span the Golden Gate strait at the mouth of the bay. An engineering student’s 1916 bridge proposal inspired real progress toward construction, then engineer Joseph Strauss took the concept and worked to get financial backing. Eventually Leon Moisseiff, who designed the Manhattan Bridge, came up with the plans for the suspension bridge that is now perhaps the preeminent symbol of this northern California city. Construction began early in 1933 and the bridge finally opened on this day in 1937. At the time, it was the longest suspension bridge span in the world. The festivities went on for a full week after auto traffic began. A song called “There’s a Silver Moon On the Golden Gate” was commissioned especially for the event. It’s as if they knew how iconic this structure would become. What are remarkable bridges that humans have constructed around the world?
