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. We may be looking at an “extinct” species of salamander. The axolotl was once found in the wild in only two places: Lakes Chalco and Xochimilco in Mexico City. The former lake is gone, while the latter has been severely altered over the years, endangering the last natural habitat for this rare amphibian. At the end of 2013, a census of the axolotl found no specimens in Lake Xochimilco. But a follow-up search at the start of this year found two still living in the wild waters. Of course, many captive specimens survive, both as pets and for scientific research. Part of the interest among scientists is the axolotl’s ability to regenerate lost limbs. Why would scientists be interested in studying the axolotl’s ability to regenerate lost limbs?
