You can drive from Maryville to Memphis in about 4 hours and the weather feels completely different. One minute you're in cool mountain air, the next you're in humid plains heat.

This lesson helps kids understand why Tennessee's weather isn't uniform. The answer is simple: elevation and geography. The mountains are higher, the plains are lower, and that changes everything about temperature and rainfall.

What You Need

A Tennessee map, a thermometer, and some way to track weather like weather.com or the Weather Channel app. A notebook for recording observations.

What to Do

Step 1: Map the Divisions

Print out a Tennessee map with the three Grand Divisions marked: - East Tennessee: Mountains (elevations 1,000-6,000 feet) - Middle Tennessee: Plateaus and Central Basin (elevations 500-2,000 feet) - West Tennessee: Flat plains (elevations 200-600 feet)

Have your child color each division differently. Talk about what elevation means: how high above sea level you are.

Step 2: Compare Temperatures

Check the current temperature in three locations: - Gatlinburg or Pigeon Forge (East, high elevation) - Nashville or Murfreesboro (Middle, medium elevation) - Memphis (West, low elevation)

Write down the temperatures. Do this for several days and track the pattern.

What you'll notice: - East Tennessee is usually 5-10 degrees cooler than the rest of the state - West Tennessee gets hotter in summer and warmer in winter - Middle Tennessee is kind of in the middle

Step 3: Track Rainfall

East Tennessee gets more rainfall because the mountains force moist air upward, which cools and drops rain. West Tennessee gets less because it's flat and far from the mountains.

Have them track weekly rainfall for each location. Notice that East Tennessee usually gets more rain, especially in spring and fall.

Why This Works

This lesson makes geography real. Kids see that elevation isn't just a number on a map. It affects how they dress, what they wear, even how their family plans vacations. If you're going to the Smokies in summer, you need a jacket. If you're going to Memphis, you don't.

Pro Tips

• Make this a week-long project. Check temperatures every morning and see if the pattern holds.
• Use Google Earth to show the elevation changes. Kids are amazed by how quickly the terrain rises in East Tennessee.
• Connect it to their lives. If you go to school in Maryville and your cousin lives in Memphis, explain why they might need a different coat than you.

If Your Child Struggles

Simplify to just two locations: where you live and where a cousin or friend lives. Compare those two. Don't introduce all three divisions at once.

Challenge Version

Have them research extreme weather events in each division. East Tennessee gets snow in the mountains. West Tennessee gets tornadoes. Middle Tennessee gets hail. Look up when these happened and write a short report.

Easier Version

Just check the temperature in two places: where you are and somewhere else. See if there's a difference. Ask which one feels warmer. Let them guess why. That's it. No pressure to know the science behind it.
