What is a Desert TutorialTeacher’s Guide
Discussion Questions1. *Thisintroductorypromptshouldbeusedbeforethestudentsviewthetutorial.
Pay attention to the three characteristics of a desert and the name of the desert. What would it be like to live in a desert? Do students think they live in a desert? Why or why not?
2. Many people pay attention to weather in the morning to plan their day. Think about what the weather has been like for the last week or the last month. Has it rained in the last week? How about in the last month? Is it supposed to rain soon? Is our climate similar to the climate in the Sonoran Desert?

3. There are large temperature extremes in the desert. Each night the temperature may decrease 30 degrees. Why does this happen? In the desert, do you see a lot of clouds? Clouds act like a big blanket to help regulate temperatures on Earth. If someone takes off your blanket during the night, do you get cold? Clouds help keep the land warm just like a blanket helps keep you warm. In the desert there are not a lot of clouds, so what happens?

Discussion Questions4. Another characteristic of the desert is quick evaporation. What does that
mean? Do you think you have ever witnessed evaporation? What happens when someone puts wet laundry on the clothing line or dishes on a drying rack? Evaporation means that water (or another liquid) is going from a liquid form to a gas form. The term for water in a gas form is water vapor. Can you think of any other examples of evaporation?

5. If you were going to travel in the Sonoran Desert to go on a nature exploration, what would you have to pack in your suitcase? We are going to be roughing it so make sure you are prepared! Do we need to bring water since cacti contain water?

2. Weather Data Collection – We learned a lot about weather and climate in deserts. Let’s do some work to find out how our weather compares to desert weather. We are going to collect and record information about this week’s rainfall and temperatures. Do we live in a desert? Do you think that the temperature will increase 30 degrees from morning to afternoon? Do you think we will collect rain water this week?

Discussion Questions1. *PresentstudentswiththisintroductorypromptbeforetheyexaminetheVirtual

The Sonoran Desert is a special desert. As you explore the Virtual Habitat, think about what makes this desert so special. Notice the different kinds of plants and animals that live here. Do you recognize any of them? How do you think their lifecycles are similar to or different from yours?
2. There are many kinds of cacti in the Sonoran Desert. Cacti are a special type of plant with green stems, spines, and no leaves. How many cacti did you learn about in the Virtual Habitat? Why do you think so many desert plants, like cacti, have spines? To look tough? For protection? What do they need protection from? Do you have any cacti near your school or near your home? Which ones?

Activities2. Habitat Charades – Each one of you will be assigned a plant or
animal in the desert community. Take some time to think about your plant or animal. Now each of you will take turns coming up to the front of the class and acting out your plant or animal. When you are acting out your character you cannot talk. Whoever guesses your character first will get to take their turn next.

3. Letter to a Senator – We can share the information we learned with others to help them understand the Sonoran Desert. Write a letter to a senator to share the information you learned about the Sonoran Desert. You could include information about the plants and animals in the desert, why the Sonoran Desert is special, why the Sonoran Desert would be an interesting place for someone to visit, and why you think we should take care of the desert.
