This activity is part of the Peak Water: Mount Everest and Global Water Supply unit.
- Ask students to think about what they know about droughts and share their ideas with a partner, then have a few volunteers share out with the class. Tell students that in this activity they will be investigating droughts, one threat to water security for people around the world.
- Watch and discuss the Climate Change and California’s Drought video. Lead a debrief discussion by asking:
- What did you notice about the reservoir? (Students' responses may include: Folsom Lake’s water levels were low. The floating docks were sitting on dry land.)
- What do you think caused the water to be so low? (Students' responses may include: Climate change; the drought has gone on for four years; there is low snowpack.)
- Watch the Droughts 101 video. Lead a debrief discussion by asking:
- What causes droughts? (Students' responses may include: Natural and human factors; changing wind patterns causing high pressure weather systems to last for too long; overuse of water supplies)
- Why do you think droughts are becoming more severe in some places? (Students' responses may include: increasing human populations are using increasing amounts of water, climate change is shifting weather patterns.)
- Based on what you have learned so far or on your own ideas, how could a drought be prevented for communities surrounding Mount Everest? (Students' responses may include: regulating water use, protecting water sources, monitoring glacier size and snowpack, reducing greenhouse gas emissions.)
2. Invite students to read about Cape Town’s “Day Zero” to understand how drought is impacting water security in a particular city.
- Have students read the article Why Cape Town is Running Out of Water and Who’s Next.
- Have students journal their responses to the article and the following questions in Section 2 of their Project Journal for this activity:
- What do you think is causing Cape Town to run out of water? (Students' responses may include: population growth and a record drought, possibly changes in climate.)
- How do you think the residents feel? (Students' responses will vary and may include: powerless, angry, scared, frustrated.)
- How do you think the residents of the Ganges (Ganga)-Brahmaputra River watershed (that you read about in the Living in Mount Everest’s Watershed article during the Watersheds activity of this unit) would feel if they ran out of water? Try to consider a specific person when you journal your responses. (Student's responses will vary.)
3. Prompt students to read an article to deepen their understanding of how climate change impacts water security.
- Have students read the How Climate Change Impacts Water Access article in pairs and discuss the main ideas. Students will complete Section 3 in the Project Journal.
- Guide students in creating a cause and effect pathway connecting climate change and water access in Section 4 of their Project Journal.
4. Revisit the Know & Need to Know chart.
- Revisit the class Know & Need to Know chart, started in the A Day Without Water activity and revisited throughout the unit, for students to see how their thinking and understanding about water has continued to change.
- Ask students to discuss with a partner:
- What do we already know about the importance of Mount Everest’s ice?
- What do we need to know?
- What questions can move from the Need to Know to the Know column?
- Prompt students to share ideas and questions in a whole-class discussion. Record new ideas and revise their questions as needed in the Know & Need to Know chart.
Students will contribute to small group and class discussions with their ideas. They will also journal their responses to the reading and video in their Project Journal: Endless Dry Spells and submit them for feedback.
Extending the Learning
Step 1: Read about the lack of snow in the Sierra Nevada Mountains in the article 500-Year Snow Fail in California’s Iconic Mountains to connect to previous lessons about snowpack and connect to the drought in this activity.
Watch this three-minute Extreme Weather: Droughts video about how droughts link to forest fires in California.

Droughts are a complex phenomenon to understand. Fortunately, the goal of this activity is not to fully explain droughts themselves, but to provide students with a baseline understanding of what causes them (the demand outweighs the supply and changing weather systems). There are different "types" of drought. A meteorological drought, for example, is not at all impacted by humans’ use of water. Climate change is worsening the duration and severity of droughts occurring today. Water security, according to the United Nations, is “The capacity of a population to safeguard sustainable access to adequate quantities of acceptable quality water for sustaining livelihoods, human well-being, and socio-economic development, for ensuring protection against water-borne pollution and water-related disasters, and for preserving ecosystems in a climate of peace and political stability.” Water security will continue to be an issue as the human population rises and the threat of drought continues.
- Students should know what freshwater is, how people use water, and where most fresh water comes from. They should have a sense of how the National Geographic and Rolex's Perpetual Planet Extreme Expedition to Mount Everest connects to water security.
