Activity 01
Gallery Walk: Hurricane vs. Blizzard Case Studies
Post four to six station sheets around the room, each featuring a real storm (e.g., Hurricane Katrina, the 1993 Storm of the Century). Students rotate in small groups, recording formation conditions, impacts, and affected regions on a shared graphic organizer. Groups then compare their notes to identify patterns across storm types.
Explain what conditions are necessary for a massive storm like a hurricane to form.
Facilitation TipDuring the Gallery Walk, place case study stations around the room and provide sticky notes so students can record observations and questions at each one.
What to look forPresent students with two scenarios: one describing warm ocean waters and thunderstorms, the other describing cold air meeting moisture. Ask students to identify which scenario is more likely to lead to a hurricane and which to a blizzard, and to list one key characteristic of each storm type.

Activity 02
Think-Pair-Share: Ocean Temperature and Hurricane Strength
Pose the question: 'If Atlantic sea surface temperatures rose two degrees Celsius, how would hurricane season change?' Students think independently for two minutes, then discuss with a partner, then share with the class. Anchor the debrief to current scientific data on sea surface temperature trends.
Compare the formation and impacts of hurricanes and blizzards.
Facilitation TipFor the Think-Pair-Share, assign pairs before the discussion so students feel ready to contribute ideas immediately after reading about ocean temperatures.
What to look forFacilitate a class discussion using the prompt: 'Imagine you are advising a family living on the coast of Florida during hurricane season and another family in Chicago during winter. What are the top two safety concerns you would discuss with each family, and why are these concerns different for each location?'

Activity 03
Simulation Game: Build a Hurricane in a Pan
Students use a large bowl of warm water, food coloring, and a hair dryer to simulate the rising warm air and rotation that drives hurricane formation. They record observations, sketch the resulting circulation pattern, and connect it to the Coriolis effect and pressure gradients discussed in earlier lessons.
Analyze the role of ocean temperature in hurricane development.
Facilitation TipSet up the Hurricane in a Pan station with clear safety boundaries and explain how the warm water and fan simulate real hurricane conditions before students begin.
What to look forOn an index card, have students draw a simple diagram comparing a hurricane and a blizzard. They should label at least two key differences in their formation or impacts, such as the water temperature needed or the type of precipitation.

Generate Complete Lesson→A few notes on teaching this unit
Teachers should emphasize the differences between the two storm types by contrasting their energy sources and impacts. Avoid combining lessons on hurricanes and blizzards into a single unit; instead, highlight their distinct characteristics. Research shows that students learn severe weather best when they physically model the systems, so simulations and case studies are essential.
Students will explain how warm ocean water feeds hurricane formation and how Arctic air interacts with moisture to produce blizzards. They will also compare the structures and dangers of each storm type, using clear scientific language and evidence from their activities.
Watch Out for These Misconceptions
During the Gallery Walk: Hurricane vs. Blizzard Case Studies, watch for students who confuse the scale or structure of hurricanes and tornadoes.
Use the case study images and scale diagrams at each station to prompt students to compare the size and shape of each storm type, noting that hurricanes span hundreds of miles while tornadoes are much smaller.
During the Hurricane in a Pan simulation, listen for students who describe blizzards as simply heavy snowstorms.
Ask students to observe the wind speed and visibility in their simulation, then compare these to the blizzard definition: sustained winds of at least 35 mph and visibility below a quarter mile for three or more hours.
During the Think-Pair-Share: Ocean Temperature and Hurricane Strength, watch for students who think the eye of a hurricane is the most dangerous part.
Use the pair discussion prompt: 'Why might people in the eye think the storm is over?' to redirect their thinking to the eyewall, where the strongest winds and heaviest rainfall occur.
