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. Jordan celebrates 68 years of independence today, but Petra, one of the country’s most famous cities, has been around considerably longer. Believed to date back to the early 300s BCE, Petra was once a vital oasis on a major trade route between the Mediterranean and the Persian Gulf. During the earliest centuries of Petra’s existence, some of the city’s larger cave dwellings were enhanced with detailed carvings on the caves’ outer walls, designed to emulate Roman architecture. Unknown to the Western world until 1812, the ruins of Petra are now one of Jordan’s biggest tourist attractions. El Deir, seen here, is one of the largest facades in all of Petra. It’s also the farthest from the tiny slot canyon entrance that funnels visitors into and out of the empty city.
