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. The Amargosa mountains mark the eastern edge of Death Valley National Park. Here, sunrise washes the hills with purple light. By afternoon, the sun will bake the park, which consistently reaches triple digits on the Fahrenheit scale, even in September. But even with the ominous name, Death Valley is a vibrant wilderness that challenges our expectations of what “wilderness” means. That’s why it’s part of the lands protected by the Wilderness Act of 1964, which was signed into law 50 years ago today.
