Words to know

primary source
Original information you collect or that comes first-hand: your field observations, measurements, photos, interviews, raw data.
secondary source
Information that someone else has collected and interpreted: reports, articles, textbooks, maps made by others.
GIS (geographic information system)
Computer software that stores, layers, analyses and maps spatial data.
geospatial technology
Tools that collect or use location data: GIS, GPS, satellite images, online map tools.
data layer
One set of mapped information (for example, rivers, roads or buildings) that can be stacked with others in GIS.
thesis
A clear statement of your answer to the inquiry question, which the rest of your work supports.
citation
A note that tells where information came from, so others can check it.
transferable skill
A skill learned in one context that can be used in many others, such as analysing data or communicating clearly.

Your turn to be the geographer

Throughout this unit you have used pieces of the geographic inquiry process: asking questions, reading climate graphs, judging sources, mapping hazards and assessing responses. Now you will put it all together and run a complete investigation, the way professional geographers, planners and scientists do.

This lesson walks through a model inquiry using a made-up town, then gives you a choice of real issues to investigate yourself.

Step 1: Formulate questions (A1.1)

Start with a topic you care about, then narrow it into an inquiry question that is open, focused and researchable. Use the concepts of geographic thinking to sharpen it.

Topic: flooding in a river town. → Too broad: "Floods in Canada." → Too narrow: "When did Riverton last flood?" → Inquiry question: How vulnerable is Riverton to river flooding, and what is the best way to reduce its risk? (spatial significance, interrelationships, geographic perspective)

Add supporting questions: Where is the floodplain? How many buildings are in it? Who lives there? What have other towns done?

Step 2: Gather and organize information (A1.2)

Use both kinds of sources:

  • Primary: field observations (walk the riverbank, photograph high-water marks, note storm drains), measurements, interviews (residents, a conservation authority staff member), a short survey.
  • Secondary: floodplain maps from the conservation authority or municipality; climate data from Environment and Climate Change Canada; census data from Statistics Canada; reports and reliable news.

Organize as you go: a table of data, a source log (who, what, when, link), and notes sorted under your supporting questions.

Step 3: Assess sources (A1.3)

For each source, ask: Who created it and what is their expertise? When was it made (is it current)? What evidence does it use? What is its purpose, and could it be biased (for example, a developer's brochure about a riverside condo)? Does another reliable source agree? Keep the most credible sources and note the limits of the others.

Step 4: Use geospatial technologies (A1.4)

GIS lets you stack layers of information for the same place and look for relationships. Free tools include online map viewers from governments, conservation authorities and Natural Resources Canada, as well as Google Earth and ArcGIS Online, which many Ontario schools can use. You can also make simpler maps by hand or with drawing tools.

Every finished map needs these elements (some teachers remember them as TODALSS): Title, Orientation (north arrow), Date, Author, Legend, Scale and Source.

Worked example

Modelled example: Interpreting the data (A1.5)

Our made-up town of Riverton has these (made-up) data: 120 buildings in total, 30 inside the 1% flood zone. Of those 30, 8 are homes with basement apartments, 1 is a seniors' residence and 1 is the fire station. The main road crosses the flood zone. Interpret the data using the concepts of geographic thinking.

  1. Percentage at risk: 30 ÷ 120 = 0.25, so 25% of buildings are in the flood zone.
  2. Spatial significance: the fire station and the seniors' residence are both inside the flood zone; emergency response could be cut off just when it is needed, and residents with limited mobility are exposed.
  3. Patterns: the at-risk buildings cluster along the river's inner bend, where the floodplain is widest.
  4. Interrelationships: the main road crosses the flood zone, so a flood could split the town in two.
  5. Geographic perspective: residents, the seniors' residence, the town council, the conservation authority and the local First Nation may weigh options differently.

A quarter of Riverton's buildings, including two critical facilities, are exposed. The town's vulnerability is high mainly because of where key services are located.

Worked example

Modelled example: Concluding and communicating (A1.6)

Write a thesis and an outline for a recommendation to Riverton's council.

  1. Thesis: Riverton should move its fire station out of the flood zone and create a buyout program for the most at-risk homes, while improving flood warnings for everyone in the zone.
  2. Evidence 1 (exposure): 25% of buildings, including the fire station and a seniors' residence, are in the 1% flood zone (map and table).
  3. Evidence 2 (vulnerability): basement apartments and a seniors' residence house people who would find evacuation hardest (interviews, census data).
  4. Evidence 3 (comparison): Ontario's practice since Hurricane Hazel of keeping development off floodplains has reduced flood losses (secondary sources).
  5. Counter-argument and response: buyouts are costly and emotionally hard; the town could start with willing sellers and pair the program with fair compensation and support.
  6. Communicate: a short report, the map, a graph, and a list of sources with citations; use correct terms (exposure, vulnerability, mitigation).

A strong conclusion answers the inquiry question directly, uses evidence from several sources, addresses other perspectives respectfully (A2.2), and is supported by a map with all its elements.

🔎 Transferable skills

Inquiry builds skills you will use everywhere (A2.1): asking good questions, finding and checking information, analysing data, making maps and graphs, working with people who see things differently, and explaining your thinking clearly. You will use them in Grade 10 history and civics, in science investigations, and in everyday life, such as deciding where to live, reading a flood map before buying a home, or judging a news story about a disaster (A2.3).

Hands-on activity

Your own mini-inquiry

Choose one issue (or propose your own, with a grown-up's approval):

  1. How vulnerable is my community to flooding, and how could the risk be reduced?
  2. How has land use in my local watershed changed natural processes (runoff, erosion, wetlands)?
  3. How is climate change affecting a specific Canadian region, and how well is it adapting?
  4. How do different communities value a natural area near me, and how should it be managed?
  5. How is a current event (a wildfire season, a flood, an earthquake) connected to the physical geography of the place where it happened?

Do the steps:

  1. Write an inquiry question and three supporting questions.
  2. Collect at least one primary source (photos, observations or an interview) and three secondary sources; log and assess each.
  3. Make one map (online or by hand) with all seven map elements, and one graph or table.
  4. Write a one-page conclusion with a thesis, evidence, a counter-argument and a recommendation. Cite your sources.
  5. Reflect: which concept of geographic thinking helped most? What skill would you use in a future job?

Grown-up note: field work should be done with a grown-up; stay well back from riverbanks, especially in spring and after storms, and never go onto ice.

For parents and teachers

Big idea: This lesson pulls together strand A of CGC1W (geographic inquiry and transferable skills: A1.1 to A1.6 and A2.1 to A2.4) and applies it to strand B issues (B2.2, B2.3 and others). The Riverton town and its data are made up for modelling; your teen's own inquiry should use real local sources.

How to help:

  • Help choose a manageable, local issue. Your municipality and local conservation authority websites often have flood maps, watershed reports and climate plans.
  • Go along on any field observations; keep well back from fast or high water.
  • Ask your teen to explain the map: "What does this legend mean? Where is north? How far is 500 m?"

Common difficulties: questions that are too broad; relying on one source; maps missing elements; conclusions that do not answer the question. Use the checklist in the activity.
