Unit overview

Big idea, essential questions, enduring understandings, standards, and materials.

Big idea

The land of Eastern Washington was shaped over deep time by lava floods and Ice Age waters. People have lived with this land since time immemorial. Later eras of exploration, settlement, treaties, statehood, and modern growth layered new stories on top of older ones. Fourth graders can connect geology, Indigenous history, and civic life using evidence and respectful language.

Essential questions

  • How do basalt layers and Ice Age floods help explain the land we see near Richland today?
  • What does it mean that Plateau peoples have lived here since time immemorial?
  • How did exploration, immigration, and treaties change life for different groups?
  • How did Washington become a state, and how did farms, railroads, dams, and wartime work reshape communities?
  • How does the past still inform choices about land, water, respect, and citizenship today?

Enduring understandings

  • Landforms are evidence of past processes we can read like clues.
  • Indigenous nations are living sovereign nations with deep ties to place.
  • Historical events look different from different perspectives.
  • Treaties are nation-to-nation agreements with lasting importance.
  • Strong historians use timelines, vocabulary, and claim-with-evidence thinking.

Columbia River Basalts; Missoula floods and scablands; reading the Eastern WA landscape today; map work; geology vocabulary.

Week 1 objectives

  • Describe lava floods of the Columbia River Basalt Group in kid-friendly deep-time language.
  • Explain how stacked basalt layers create stair-step cliffs.
  • Retell the Missoula floods story: ice dam, Glacial Lake Missoula, repeated floods, coulees, Dry Falls, scablands.
  • Connect local Richland / Tri-Cities landscape clues to the geologic story.
  • Use a simple map key for river, plateau, and major landforms.

Key vocabulary

  • basalt, lava flood, Columbia Plateau, layer / strata
  • Ice Age, ice dam, Glacial Lake Missoula, Missoula floods
  • coulee, channeled scablands, Dry Falls
  • sagebrush country, evidence, landform

Assign Study Guide: Basalt floods; Missoula floods; Reading the land today; Week 1 review box.

Day-by-day suggested flow

Day 1 -- Hook the land under our feet

Flow: Look out the window or at land-today image. Ask: What clues do rock and river give us? Introduce deep time with a simple analogy (school year vs. millions of years). Read Study Guide basalt opening paragraphs together.

Activity: Layer-cake demo (paper strips or stacked books labeled as lava floods). Students sketch a stair-step cliff and label "older layer" / "newer layer."

Formative: Exit ticket -- "Basalt is ______ because ______."

Differentiation: Provide labeled diagram; partners for sketch; oral dictation option.

Day 2 -- Columbia River Basalt Group

Flow: Reread basalt section. Discuss why cliffs look stair-stepped. Vocabulary card sort: basalt / plateau / lava flood / layer.

Activity: Map work -- shade approximate Columbia Plateau on a WA outline; mark Columbia River.

Discussion: "If lava floods happened again and again, what evidence should still be visible?"

Formative: Two-sentence summary on sticky note.

Day 3 -- Missoula floods story

Flow: Tell ice-dam story with gestures (lake grows, dam fails, water races). Read Missoula study section. Emphasize repeated floods, not one single event.

Activity: Sequence cards: ice dam forms / lake fills / dam fails / flood carves land / dam rebuilds.

Discussion: "How is a Missoula flood different from a rainy-day puddle?"

Formative: Order the five cards correctly in notebook.

Day 4 -- Coulees, Dry Falls, scablands, Tri-Cities connection

Flow: Image walk: coulee, scablands, Dry Falls, local basalt walls. Connect to places students may know (river cliffs, open channels, sagebrush hills).

Activity: "Evidence detective" chart: Feature / What it suggests / How I know.

Formative: One row of the chart completed accurately.

Differentiation: Pre-filled first row; word bank on board.

Day 5 -- Week 1 synthesis

Flow: Complete Week 1 review box in Study Guide. Partner teach: one student teaches basalt, one teaches Missoula.

Activity: Mini quiz oral whip-around or Study Guide matching practice from packet Section A (geology items).

Formative: Week 1 check -- 4 question quick quiz (paper or board).

Assign: Finish any unread Week 1 study pages; preview Week 2 opener.

Discussion prompts (Week 1): What clues in today's landscape remind us of basalt floods or Ice Age floods? Why do scientists need the idea of "millions of years" for this story? Which landform near home feels most connected to this unit so far?
Week 2 of 4

Since time immemorial

Plateau (and brief coastal contrast) cultures; rivers, salmon, and trade; oral history as source; respectful norms; STI companion lessons.

Week 2 objectives

  • Explain "since time immemorial" in student language.
  • Describe seasonal living, villages/trade, and salmon importance for Plateau peoples.
  • Name several Plateau nations carefully (Yakama, Nez Perce, Umatilla, Cayuse, Walla Walla, Wanapum, Spokane, Colville Confederated Tribes, and others as appropriate).
  • Contrast coastal and Plateau environments at a high level without stereotypes.
  • Treat oral history as a valid historical source; practice respectful classroom norms.

Key vocabulary

  • since time immemorial, Indigenous, tribal nation, Plateau peoples
  • homeland, salmon, seasonal round, trade network
  • oral history, respect, sovereignty (intro)
  • Coast Salish (brief contrast term)

Assign Study Guide: Plateau peoples; Coastal contrast; Week 2 review. Launch STI Tribal Homelands / Salmon lessons in parallel.

Day-by-day suggested flow

Day 1 -- Since time immemorial as the right starting point

Flow: Reset the timeline: geology first, then people long before written U.S. history. Teach the phrase since time immemorial. Read opening Plateau peoples paragraphs.

Activity: Norms chart: We use accurate names. We do not invent sacred stories. We listen for living cultures, not "only in the past."

Formative: Students restate one classroom norm in their own words.

Day 2 -- Rivers, salmon, seasons, trade

Flow: Deep read on seasonal living and salmon. Link to Columbia River on the map. Discuss trade as connection, not isolation.

Activity: Season wheel: spring / summer / fall / winter -- place sample activities from the reading (fishing, gathering, travel, village life) with teacher guidance. Avoid inventing ceremonial detail.

Discussion: "Why should historians start Washington's people story with Native nations?"

Formative: One evidence sentence: "Salmon mattered because ______."

Day 3 -- Nations of the Plateau (careful naming)

Flow: Introduce major Plateau peoples with map dots. Stress diversity: many nations and bands, not one single culture. Note living communities today.

Activity: Name-and-place matching with a simple map key (teacher-created cards).

Differentiation: Fewer cards for some students; challenge extension = add one respectful fact from STI materials.

Formative: Exit ticket naming two Plateau nations and one shared theme (river/salmon/trade).

Day 4 -- Brief coastal contrast + oral history

Flow: Compare environments: coastal rain forests and ocean resources vs. inland rivers and drier plateau. Shared PNW themes: family, water, trade, deep time on the land.

Activity: Venn diagram (Coastal / Both / Plateau). Mini lesson: oral history is a source historians take seriously.

Formative: Two items correctly placed in the Venn.

Day 5 -- STI companion day + Week 2 review

Flow: Teach or continue an OSPI STI elementary lesson (Tribal Homelands or Salmon). Complete Week 2 review box.

Activity: Respectful Q&A protocol: "One fact I know / One question I still have."

Formative: Week 2 check -- short answers on salmon + since time immemorial.

Discussion prompts (Week 2): Why is "since time immemorial" more accurate than "before explorers"? How can oral history help us understand the past? What does respectful curiosity look like when we learn about tribal nations?
Week 3 of 4

Encounter to treaties

Exploration and trade; immigration and settlement; Oregon Trail era (age-appropriate); treaties and territory; multiple perspectives.

Week 3 objectives

  • Describe maritime and overland exploration/trade in the late 1700s-1840s as encounter, not empty-land discovery.
  • Summarize Lewis and Clark era travel on the Columbia with Native presence centered.
  • Explain fur trade posts as meeting places that changed relationships.
  • Describe why newcomers immigrated and how settlement created conflict over land.
  • Define treaty, territory, and sovereignty; acknowledge broken promises as historical fact framed for 4th grade.

Key vocabulary

  • exploration, encounter, maritime, overland
  • fur trade, trading post, immigration, settlement
  • Oregon Trail (age-appropriate), pioneer (use carefully)
  • treaty, territory, sovereignty, perspective, promise

Assign Study Guide: Exploration and trade; Fur trade; Immigration and settlement; Treaties and territory; Week 3 review.

Day-by-day suggested flow

Day 1 -- Exploration as encounter

Flow: Teach the difference between "discovering empty land" and "meeting people who already live there." Read exploration section. Place late 1700s-1840s on the class timeline.

Activity: Claim stem: "Exploration changed the region because ______."

Formative: Students avoid empty-land language in their stem.

Day 2 -- Lewis and Clark era on the Columbia + fur trade

Flow: Map the Columbia route at a simple level. Emphasize Native knowledge, trade, and guiding. Read fur trade paragraphs: posts as exchange hubs.

Activity: Two-voice poem or dual journal: trader / Plateau community member (keep factual, not cartoonish).

Discussion: "How can two groups experience the same meeting differently?"

Formative: One accurate detail from each voice.

Day 3 -- Immigration, trails, and settlement pressure

Flow: Why people came (land, farms, new starts). Age-appropriate Oregon Trail: long hard journey, not a game. Farms and towns grow; pressure on Indigenous homelands increases.

Activity: Cause/effect chart: Newcomers arrive / Effects for settlers / Effects for tribal nations.

Differentiation: Sentence frames for each column; advanced students add a third effect.

Formative: Chart has at least one valid effect in each column.

Day 4 -- Treaties, territory, sovereignty

Flow: Define treaty as nation-to-nation agreement. Define territory (Washington Territory before 1889). Introduce sovereignty. State clearly that many promises were broken -- calm, factual, 4th-grade framing.

Activity: Vocabulary triangles: word / kid definition / why it matters.

Sensitive tip: Watch for overload; use "One fact / One question" protocol.

Formative: Correct kid definitions for treaty and sovereignty.

Day 5 -- Multiple perspectives + Week 3 review

Flow: Practice perspective stems. Complete Week 3 review. Optional STI Celilo Falls connection if timing allows.

Activity: Mini debate rules = respectful evidence only (no winners needed): "Why do treaties still matter?"

Formative: Week 3 check -- matching treaties/territory/sovereignty + one short answer.

Discussion prompts (Week 3): What does a treaty ask people to remember and respect? Why is "multiple perspectives" an important tool for settlement and treaty study? How should we talk about broken promises without shutting down curious learners?
Week 4 of 4

Statehood to today

1889; growth of cities, farms, irrigation, and dams; WWII Hanford/Richland carefully; modern WA civic/economy/environment; cumulative assessment.

Week 4 objectives

  • Lock 1889 as Washington statehood and explain territory-to-state change.
  • Describe railroads, towns, farming, and irrigation in Eastern WA.
  • Explain dams as change for people and fish (tie to earlier salmon knowledge).
  • Describe Hanford/Richland growth in age-appropriate wartime science/engineering terms.
  • Connect past to present: industries, cities, agriculture, tribal nations today, civic life.
  • Produce a final claim-with-evidence paragraph.

Key vocabulary

  • statehood (1889), railroad, irrigation, dam
  • Hanford, Richland, wartime project, secret city (careful)
  • industry, agriculture, environment, civic life
  • claim, evidence, lasting impact

Assign Study Guide: Path to statehood; Railroads/towns/farming; Dams and rivers; WWII Hanford/Richland; Modern Washington; Week 4 review; full packet; quiz rounds.

Day-by-day suggested flow

Day 1 -- 1889 statehood and growth

Flow: Memory hook: 1889. Read statehood section. Add to timeline. Discuss that statehood adds a chapter; it does not erase Native history.

Activity: Before/after statehood T-chart (government status / daily life examples from reading).

Formative: Students write 1889 correctly and one non-erasure sentence.

Day 2 -- Railroads, towns, farming, irrigation

Flow: How trains linked towns and markets. Eastern WA farming needed water: irrigation canals and systems. Connect to dry climate vs. river water.

Activity: Systems sketch: river -> canal -> farm -> town -> railroad.

Formative: Labeled sketch with at least four parts.

Day 3 -- Dams, rivers, salmon connection

Flow: Dams changed power, flooding patterns, irrigation, and fish passage. Revisit Week 2 salmon knowledge. Keep tone balanced: benefits and costs.

Activity: Two-column notes: Ways dams helped people / Ways dams changed fish and rivers.

Discussion: "How do rivers still shape life in Eastern Washington?"

Formative: One valid note in each column.

Day 4 -- Hanford / Richland carefully + modern Washington

Flow: Age-appropriate: huge WWII science/engineering project; secret-city growth; lasting community identity. No graphic weapon detail. Then modern WA: cities, farms, tribal nations today, civic life.

Activity: Local identity web: work / science / river / schools / family stories (invite careful sharing).

Sensitive tip: Families may have local ties; listen; keep factual.

Formative: One careful factual sentence about Richland growth + one modern connection.

Day 5 -- Cumulative assessment day

Flow: Complete remaining packet sections. Run quiz (8 of 24+). Write final claim-with-evidence paragraph. Celebrate timeline mastery.

Activity: Final paragraph using stem: "My claim about Washington history is ______ because ______." Optional share-aloud.

Summative pieces: Packet accuracy, quiz practice score (formative or light grade), paragraph rubric (claim clarity + evidence + respectful language).

Discussion prompts (Week 4): What year should every classmate lock in for statehood? How did irrigation and dams change both farms and fish? What is one careful, factual way to describe why Richland grew in the 1940s? How does the past still inform decisions today?
