Session 1, Read and notice: Water crosses boundaries

Week 22 big question: How can groups share what they find and make a plan better?

Start with a story (optional) Decision — Read it hereSupporting match · When the village tap runs dry, neighbors meet and decide to work together.

Lakes, fish and boats cross the lines on maps.

Imagine steering a boat across a border on the Great Lakes. No line on the water tells you to stop there. Lakes Superior, Michigan, Huron, Erie and Ontario form one connected water system. The United States and Canada share this region. Lake Michigan is all in the United States. Fish and pollution can cross the border too.

Two countries signed a plan to care for the lakes.

So how can two countries care for water they both share? In 1972, the United States and Canada signed a plan. It was a plan to care for the lakes. Its name was the Great Lakes Water Quality Agreement. Both countries agreed to cooperate. They would protect the lakes and make the water healthy again. Since then, they have updated the agreement. They have shared research, goals and work to cut pollution. The International Joint Commission checks progress, studies problems and listens to the public.

Many people work on it, and they check if it helps.

But a signed paper cannot clean a lake on its own. Scientists and people in towns join many governments in this work. These include national, state, provincial, local and Indigenous governments. Though groups may disagree about what comes first, they all need healthy water. They share what they observe, talk about it, then act and check the results. An agreement starts the work, but checking shows whether it helps. Your family can try those steps when you share a problem.

Look and think

Show what you notice

  1. Why does more than one country need to care for the lakes?
  2. What could a group check to see if its agreement is working?

Session 2, Investigate: Compare before choosing

Test two designs the same way, then choose.

Your partner is two big steps away, waiting for your message. Will a soft tap or a flash of light work better? A cup’s wide top gives you a place to tap. A paper hood blocks light at a flashlight’s sides. Each design sends a message, but the best choice depends on your partner. Sound may reach someone who is not facing you. Light can keep a room quiet. But your partner must see the light to get the message. Engineers call each need a criterion, such as a clear, comfortable message. In our test, both designs use the same distance, codes and number of trials. Your partner’s comfort matters too, so ask how each message felt. Which design fits your partner and the place best?

Set up the test

Gather paper cup or small lidded container · flashlight · paper hood and tape · white target card · ready card · paper

Safety Use gentle sounds and slow light changes below eye level. Adults tape a loose hood without covering vents or switches. No rapid flashing; stop for discomfort.

  1. Ask your partner what a good ready message needs. Agree: comfortable, and understood two big steps away.
  2. Sketch the cup and the flashlight with a hood. Label the wide top and the sides of the hood.
  3. Send three mixed-up messages with each tool from the same spot. Record what arrived and how it felt.Adult: Agree first: one signal means ready, and two mean wait.
  4. Choose or improve one design. Test it again. Tell why it fits this partner.

Session 3: Record and make — A shared problem meeting

A shared problem meeting

Groups who care for the Great Lakes meet and share what they find. Hold your own meeting about the tools you tested.

  1. Find the United States, Canada and the Great Lakes on the map. Tell one way the countries cooperate.
  2. Each partner shares their tool’s trial record and how comfortable it felt.Adult: Compare the tools, never how well a person sees or hears.
  3. Agree on a tool or a fix. Tell one benefit, one limit and who does the next step.

Connect the ideas. We must choose a plan as a group. How does sharing what we saw help?

How to run this week, in a few minutes.

At a glance

Time

From the workbook: Read and notice about 20 min · Investigate 20–30 min, plus short checks · Record and make 20–30 min.

Core

Test two signal designs the same way, and choose one with evidence.

Materials
  • paper cup or small lidded container
  • flashlight
  • paper hood and tape
  • white target card
  • ready card
  • paper
Safety

Use gentle sounds and slow light changes below eye level. Adults tape a loose hood without covering vents or switches. No rapid flashing; stop for discomfort.

Short week

Read together, then do Investigate steps 1–3 and the evidence page. If you skip design improvement and retesting, note it as “not yet” for your teacher.

Next week

Keep the first sketch and revision. Improvement does not require perfect success; a documented limitation is useful engineering evidence.

Library books

  • One Well: The Story of Water on Earth by Rochelle Strauss. Shows that all people share one connected water supply (listed ages 8+; fine as a read-aloud).
  • Ada Twist, Scientist by Andrea Beaty. A curious girl runs experiments to compare ideas.
Answer key (for grown-ups)

Talk together

  1. Why does more than one country need to care for the lakes?
    The connected lakes and region are shared; pollution and water movement can affect communities across boundaries. Michigan is entirely within the United States.
  2. What could a group check to see if its agreement is working?
    Water observations, pollution measurements, and reports from affected communities can help assess progress. A signature alone does not establish improvement.

What to expect in the investigation

Either device may work better in the chosen setting. Sound can reach someone not facing the sender; light may suit a quiet setting but needs visibility. Access needs vary. Record actual comfort and trial outcomes. A sketch shows how shape helps: the cup’s wide top is easy to tap, and the hood blocks sideways light. Compare what each does well and badly; the best choice depends on the people and the place.

Checkpoint question

Tests plus user feedback support a need-based choice. Reteach by asking what each record tells us.
