FREE Winter CER Activities: Blizzards, Inversions & Power Grids | Middle & High School for 2025 & 2026
Share
Winter weather offers perfect opportunities for data analysis, if you have the right resources. Students see blizzard warnings and power outages on the news, but do they understand the science behind wind chill calculations, temperature inversions trapping pollution, or why electrical grids fail during extreme cold?
We've created three FREE Claim-Evidence-Reasoning activities featuring authentic winter weather data that transform abstract concepts into concrete analysis. Each activity includes multi-variable graphs, scaffolded CER prompts, complete standards alignment, and detailed sample student responses that model strong scientific reasoning.
Here's how these resources bring winter science to life in your classroom.

The Winter Data Analysis Challenge
Your students can probably define a blizzard or describe how pollution affects air quality. But ask them to analyze multi-variable data showing how wind speed transforms -8°F into a life-threatening -42°F, or why temperature inversions cause air quality to deteriorate from "good" to "unhealthy" in just three days, and you'll discover their analytical skills need development.
The missing piece? Practice with real scientific data that tells compelling stories about phenomena they experience.
Three Winter Phenomena, One Comprehensive Resource
Our FREE winter CER activities provide authentic data analysis practice across three critical topics:
Activity 1: Wind Chill and Blizzard Safety

Students analyze 24-hour blizzard data tracking actual temperature, wind speed, wind chill temperature, and snow accumulation. They discover how 50 mph winds create 30-40°F temperature differences and why frostbite timing matters for winter safety.
- MS-ESS2-5: Collect data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions
- MS-ESS3-3: Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment
- HS-ESS2-4: Use a model to describe how variations in the flow of energy into and out of Earth's systems result in changes in climate
- HS-ESS3-4: Evaluate or refine a technological solution that reduces impacts of human activities on natural systems
Activity 2: Temperature Inversions and Air Quality

Real atmospheric data shows how winter inversions trap cold air near the ground, preventing pollutant dispersion. Students track Air Quality Index rising from 45 (good) to 165 (unhealthy) as the inversion strengthens over five days, connecting weather patterns to public health.
- MS-ESS2-5: Collect data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions
- MS-ESS3-2: Analyze and interpret data on natural hazards to forecast future catastrophic events
- HS-ESS2-4: Use a model to describe how variations in the flow of energy into and out of Earth's systems result in changes in climate
- HS-ESS3-1: Construct an explanation based on evidence for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity
Activity 3: Temperature and Power Demand

Seven days of utility company data reveals the inverse relationship between temperature and electricity consumption. Students see demand surge 60% during extreme cold and explain why grids become vulnerable precisely when heating is most critical.
- MS-PS3-3: Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer
- MS-ESS3-3: Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment
- HS-PS3-3: Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy
- HS-ESS3-2: Evaluate competing design solutions for developing, managing, and utilizing energy and mineral resources based on cost-benefit ratios

What Makes These Activities Work
Each activity features interactive graphs with real or research-based data, comprehensive background information that builds content knowledge, and detailed sample responses modeling sophisticated scientific reasoning. They're aligned to both NGSS and TEKS standards across middle and high school levels, addressing topics from molecular structure to ecosystem dynamics.

The winter context provides natural engagement, but the real learning comes from the CER framework that guides students through making specific claims, citing precise evidence, and explaining the scientific principles connecting their evidence to conclusions.
