Colorado's Story: Rocky Mountains, Silver Mines & Mesa Verde's Mystery

Colorado has 58 mountains taller than 14,000 feet — more than any other state. That means 58 mountains so tall the air is thin, the weather changes in minutes, and you can look out and see FOUR other states at once! Let's make a snowy mountain and discover the animals that live up there.

How this changes by age

Pre-K (ages 3–4)

Colorado has 58 mountains taller than 14,000 feet — more than any other state. That means 58 mountains so tall the air is thin, the weather changes in minutes, and you can look out and see FOUR other states at once! Let's make a snowy mountain and discover the animals that live up there.

Difficulty 1 of 3

Steps

  1. Say: 'Colorado's Rocky Mountains are so tall that even in summer, the very tops are covered with snow. The weather can go from sunshine to a snowstorm in 20 minutes. Animals that live up there have to be tough!'
  2. Scrunch white paper into a tall pointed mountain shape. Press the bottom flat on blue paper.
  3. Draw snowy streaks coming down the sides with a white crayon.
  4. Draw a bighorn sheep with big curling horns standing on a ledge — say: 'Bighorn sheep can leap between rocks 20 feet apart and their hooves have a rubbery grip, like built-in sneakers!'
  5. Ask: 'If you were a mountain animal, which superpower would help you survive: thick fur, strong legs, or amazing eyesight? Why?'

Learning objectives

  • Identify the Rocky Mountains as Colorado's defining geographic feature
  • Wonder at how animals adapt to extreme mountain environments

Kindergarten (ages 5–6)

Around 1300 AD, the people of Mesa Verde — who had spent 700 years building spectacular cliff cities — packed up and left. Every single one of them. Gone. And no one knows for certain why. Drought? A long journey to find something better? The mystery is still unsolved today. Let's build a cliff dwelling and think like a detective.

Difficulty 2 of 3

Steps

  1. Tell the story: 'For 700 years, the Ancestral Puebloans built amazing homes right into the faces of cliffs in Colorado. Then around 1300, they vanished — completely. Archaeologists have found pottery, baskets, even food — but not a single written explanation. It's one of the great unsolved mysteries of North America.'
  2. Build a small cliff town: toilet paper roll as a mine tunnel, small boxes as buildings stacked on a table edge to look like a cliff face.
  3. Make a 'MYSTERY BOARD' — write 3 possible reasons people might leave a home forever: drought (no rain), a long journey to find new land, or a new opportunity somewhere else.
  4. Ask: 'If YOUR family had to move away and never come back, what would you leave behind? What would you take?'
  5. Write 'UNSOLVED' in big letters on the mystery board — that's honest history!

Learning objectives

  • Learn about the Ancestral Puebloans and their Mesa Verde cliff dwellings
  • Understand that Mesa Verde's abandonment is a genuine unsolved historical mystery
  • Practice forming hypotheses — giving possible reasons for an unexplained event

Early elementary (ages 6–8)

Colorado became the 38th state in 1876 — exactly 100 years after the Declaration of Independence, earning it the nickname 'The Centennial State.' But long before statehood, this land held a 700-year mystery: why did the Ancestral Puebloans abandon Mesa Verde around 1300 AD? Today you'll map Colorado and investigate the mystery like a real archaeologist.

Difficulty 2 of 3

Steps

  1. Draw Colorado's perfectly square outline — it's one of only two states with right-angle borders on all four sides. (Fun fact: it was drawn on a map before surveyors measured it, so the corners are actually slightly off!)
  2. Mark: Mesa Verde (southwest), Pikes Peak (center), Denver (northeast), and the Continental Divide (diagonal line down the middle separating rivers that flow to the Pacific vs. Atlantic).
  3. Detective work: Write 3 possible reasons archaeologists have proposed for the Mesa Verde abandonment: 1) A 23-year drought from 1276-1299, 2) Evidence that groups moved toward new communities to the south, 3) New religious movements drawing people toward New Mexico.
  4. Write a paragraph: 'Based on the evidence, I think the most likely reason the Ancestral Puebloans left Mesa Verde was ___ because ___.' Use the word 'evidence.'
  5. Write a sentence explaining why Colorado is called the Centennial State.

Learning objectives

  • Identify key Colorado geographic features on a hand-drawn map
  • Evaluate three competing explanations for the Mesa Verde abandonment using evidence
  • Practice hypothesis formation and evidence-based reasoning in a historical context
  • Explain why Colorado earned the nickname 'The Centennial State'

Upper elementary (ages 8–10)

Here is a question with no easy answer: The Colorado River supplies water to 40 million people across seven states and Mexico. But the river no longer reaches the ocean — humans use every drop of it. The Colorado River Compact of 1922 divided the water before anyone knew how little there was, and it assumed the river would always carry more water than it actually does. As the West gets drier, this is becoming a crisis. Research the Compact and write an essay on who should decide how to divide a river that belongs to everyone — and no one.

Difficulty 3 of 3

Steps

  1. Research the Continental Divide: What is it, and how does it determine which ocean Colorado's rain and snow eventually reach?
  2. Research the Colorado River Compact of 1922: Which 7 states signed it? What was the allocation? What has happened to the river's actual water volume since then?
  3. Research the current crisis: Lake Mead and Lake Powell are the two largest reservoirs in the US — both fed by the Colorado River. What percentage of their capacity are they currently at? (Look it up or estimate from recent news.)
  4. Create a map of the Colorado River basin tracing the river from its headwaters in Rocky Mountain National Park to the Gulf of California. Mark the states it crosses and the major dams.
  5. Write a 4-paragraph essay: Who should have the authority to decide how a river shared by 7 states and a foreign country gets divided — and what happens when there isn't enough to go around?
  6. Discuss: If you were a mediator trying to rewrite the Colorado River Compact today, what is one change you would make? What objection would the hardest-to-convince state raise?
  7. Colorado ski resorts sell lift tickets for roughly $150–$250 a day (estimate). If a resort sells 5,000 tickets on a busy Saturday at $200, calculate daily revenue. Then list three costs the resort pays (snow machines, lift electricity, ski patrol). Why do ski towns worry about warm winters?
  8. Coloradan hard-rock miners used timber framing to keep tunnels from collapsing. Build a model tunnel frame using popsicle sticks or straws: make a square 'set' with a crossbeam. Test how much weight (books) it holds before it buckles. Then sketch one improvement to make it stronger.

Learning objectives

  • Explain the Continental Divide and its role in Western water distribution
  • Describe the Colorado River Compact and why its original allocations are now problematic
  • Write a 4-paragraph persuasive essay using geographic and historical evidence
  • Connect a 100-year-old water agreement to a current environmental crisis

Safety and evidence note

Read the full activity before beginning. An adult should supervise tools, heat, food, outdoor work, movement, and experiments as appropriate. Completion records that the activity was done; the child’s explanation, work sample, photo, or demonstration is stronger evidence of learning than a completion check alone.

Alabama's Story: Cotton, Civil Rights & Red Hills

Did you know that one woman sitting down on a bus helped change America forever? Rosa Parks sat down in Alabama — and the whole country stood up. And Alabama is also home to NASA's Marshall Space Flight Center in Huntsville — where scientists designed the Saturn V rocket that sent people to the Moon! Ten years after Rosa Parks's bus protest, thousands of people marched together across a bridge in Selma, Alabama to ask for the right to vote. Let's draw that bridge!
