This activity is part of the Climate Change Challenge unit.
1. Prompt students to gather and graph weather station data.
- In the same weather data collection groups as in the previous activities in the Extreme Weather lesson, ask students to reflect on today’s weather. Ask them to make predictions regarding how their variable will have changed when they examine today’s data.
- Assign students to collect data for their variables. They can either physically use the class weather station, or digitally with the National Weather Service Weather Observation History for the Past Three Days, as during the Meteorological Models activity.
- Students may need a reminder to enter their zip code in the upper left corner of the page, and then click on the "3 Day History" link at right-center, but should collect data today in small groups, rather than as a class, and with limited teacher assistance.
- Assign students to incorporate this data onto the second day of their point/line graph.
2. Clarify the distinctions and connections between weather and climate by viewing and discussing an interactive graph with students.
- Project the interactive Billion-Dollar Weather and Climate Disasters: Time Series Graph. Ask for volunteers to point out the following elements:
- X-axis label
- Y-axis labels (Note: There are two y-axes. The one on the left that corresponds to the number of billion-dollar disasters is most important here.)
- Help students familiarize themselves with the graph answering the following questions in a Think-Pair-Share:
- How many billion-dollar weather events occurred in 1980? (Three)
- How many billion-dollar weather events occurred in 2018? (Fourteen)
- What types of billion-dollar weather events are increasing over time? (Most types appear to be increasing. Increases in severe storms and flooding are particularly apparent.)
- What types of billion-dollar weather events are decreasing over time? (It’s not clear that any are; perhaps winter storms.)
- Prompt students to recall the distinctions between weather and climate (using their Weather Interconnections Meaning Builder from the Weather Interconnections activity, if necessary), asking:
- Does this graph contain information about weather, climate, or both? (Both. Individual events on the graph are weather. However, long term patterns, such as the increase in severe, billion-dollar storms since 1980 that students likely identified above, represent information on climate.)
3. Support students as they read to address hypotheses regarding the future frequency of extreme weather events.
- Reconvene students in their extreme weather groups from the Weather Interconnections activity.
- Challenge students to hypothesize how the frequency of their weather event will change in the future, given their understanding of carbon dioxide concentrations, global warming, and climate change.
- Direct students to record their hypotheses in Part G of the Extreme Weather Model Builder, with supporting evidence to justify their claims. (Students' hypotheses should articulate both their prediction and justification. For example, ‘I think tornadoes will increase in the future as the planet warms because they form from warm air.’ Hypotheses may incorporate prior information from the Extreme Weather Model Builder or more recent knowledge from the Billion-Dollar Weather and Climate Disasters: Time Series Graph.)
- Invite students to read and annotate an article to evaluate their hypothesis within their extreme weather groups, as follows:
- As they read, students should determine whether the article agrees with their hypothesis. They should also note the evidence presented for any of the weather variables in Part H of the Extreme Weather Model Builder handout with their group.
4. Direct students to create a final extreme weather model incorporating the effects of global warming and climate change.
- With evidence from the article, direct students to revisit their revised extreme weather model (Part E) again, noting what information (text and/or visual) would be necessary to incorporate the role of global warming and climate change in this weather event (Part H).
- On a large piece of chart paper, ask each group to draw a final model incorporating:
- Text and visuals to accurately depict the extreme weather event’s formation (from Part E).
- At least four of the six weather variables (from Part E).
- A depiction of how global warming and climate change is predicted to affect the weather variables, which will, in turn, increase or decrease the frequency of this extreme weather event (using the information recorded in Part H).
- Next, distribute copies of the Extreme Weather Model Rubric and have students self-assess their final extreme weather models. Allow time for groups to make revisions to their model, if necessary.
- Collect the final extreme weather models for assessment.
- Revisit the class Know and Need to Know chart. Encourage students to articulate any recent insights or remaining questions regarding the connections between weather and broader patterns of global warming and climate change. Emphasize that the extreme weather events they have been exploring are related to climate change.
Use the Extreme Weather Model Rubric to formally assess students’ progress towards NGSS PE MS-ESS2-5: Collect data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions.
Extending the Learning
Step 2: You may wish to download data from the interactive Billion-Dollar Weather and Climate Disasters: Time Series Graph to practice additional analyses with students. Or you may choose to assign additional research into specific extreme weather events, such as Hurricane Katrina of 2005, the El Reno tornado of 2013, or the Camp Fire of 2018. You may also wish to add discussion of the human and economic dimensions of such events, possibly in conjunction with students’ social studies educators.

Step 3: Each of the articles in this step has been leveled to accommodate readers at multiple levels.
Extreme weather events include hurricanes, tornadoes, and droughts. Each of these extreme weather events has the capacity to powerfully influence the lives of humans, and can sometimes even be deadly. The frequency and intensity of many extreme weather events have been on the rise in recent years.
Depending on the type of extreme weather event, shifts in frequency and intensity may or may not be related to global warming and climate change. For example, the destructive potential of hurricanes is increasing as sea levels rise, leading to greater storm surges. Warmer temperatures can increase the severity of drought by evaporating more water from soils. Finally, the relationship between tornadoes and climate change is currently not clear, but the subject of ongoing scientific research.
