Session 1, Read and notice: The last six sheets

Week 16 big question: What if we do not have enough for all our plans?

Start with a story (optional) Paper Play — Read it hereOne sheet of paper becomes a ball, a lollipop and more as children play.

When there is not enough, we can’t do all our plans.

Six sheets of paper lie on a pretend workshop table. Two children want to build a big model house and a model shop. But the house needs four sheets, and the shop needs three. The children count them up. They find they need more paper than they have. Paper is a limited resource, so both plans cannot work as drawn. Time, tools, land, water and work can be limited too. What could the children do?

Each choice brings a gain, but it also costs us.

They could build the house and save the two sheets left over. Or they could build the shop and save three for something else. If they plan smaller buildings or reuse clean cardboard, their choices change. Each choice brings a benefit, something helpful they gain, while also giving something up. The cost might be money, time, materials or a chance they did not take. Which plan would you choose, and what would you give up?

Bakers and shoppers must choose when there is less flour.

A real baker faces choices too when there is less flour. The bakery may make fewer loaves or change what it sells. When that happens, shoppers have different choices about what to buy. You take part in the economy when you use supplies or help make something. Like the baker, you cannot always do every plan at once. Next time you choose, name a benefit and notice what you give up.

Look and think

Show what you notice

  1. Why can’t the workshop build both plans?
  2. If there is less flour, what could change for the bakery? What could change for shoppers?

Session 2, Investigate: Can the change go back?

Some changes can go back, and some cannot.

An ice cube melts, and all you see is water. Has the ice gone for good, or could it come back? Warmth melts solid ice into liquid water, but cold can freeze that water again. This lets us reverse the change, or make it go back. The ice may have a new shape, but it is solid again. An egg changes too when an adult cooks it for a meal. Its runny parts turn firm, but cooling does not make it raw again. We see the same water melt and freeze again. This gives us evidence that its change can go back. What will you notice when you look in the freezer later?

Set up the test

Gather ice cube in a shallow freezer-safe container · freezer access · adult-prepared photos of one egg before and after cooking · cooled cooked egg in a covered clear container · paper

Safety Only adults handle raw egg, cooking, hot equipment, and freezer transfers. Keep samples covered; do not taste investigation materials. Use photos if allergies apply.

  1. Look at an ice cube and the raw-egg photo. Do not touch any egg. Predict which change can go back.
  2. Let the ice melt in the room. Compare the cooled cooked egg with the raw-egg photo.
  3. Ask an adult to freeze the melted water. Look at it again later.Adult: This check happens later, outside the main lesson.
  4. Draw two rows: ice, water, ice. Raw egg, cooked egg, cooled egg. Which one went back?

Session 3: Record and make — A choice board

A choice board

Plan the six-sheet workshop. A choice is not the same as a change in a material.

  1. Use six paper counters for the sheets. Show why the house plan and the shop plan do not both fit.
  2. Choose: build one, change the plan, or reuse something. Tell a benefit and what you give up.
  3. Add your two change rows. If the water has not frozen yet, leave that part blank. Do not guess.

Connect the ideas. Can a change go back? If a maker knows, how could that help them not waste things?

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

Make a choice with limited paper, and compare changes that do and do not go back.

Materials
  • ice cube in a shallow freezer-safe container
  • freezer access
  • adult-prepared photos of one egg before and after cooking
  • cooled cooked egg in a covered clear container
  • paper
Safety

Only adults handle raw egg, cooking, hot equipment, and freezer transfers. Keep samples covered; do not taste investigation materials. Use photos if allergies apply.

Short week

Read paragraphs 1–2, then do the Investigate steps and the evidence page.

Next week

Discuss repair and reuse of a familiar object. Keep family finances private; tokens are enough for economic reasoning.

Library books

  • Alexander, Who Used to Be Rich Last Sunday by Judith Viorst. Alexander's money runs out as he makes choices about spending.
  • Change It! Solids, Liquids, Gases and You by Adrienne Mason. Explores changes like freezing and melting, including which can be reversed.
Answer key (for grown-ups)

Talk together

  1. Why can’t the workshop build both plans?
    Four plus three requires seven sheets, but only six are available. Reusing or redesigning changes the plan, not the original arithmetic.
  2. If there is less flour, what could change for the bakery? What could change for shoppers?
    Less flour may mean fewer loaves produced. A consumer might buy another food, wait, or use food already available. Do not assume every shortage changes prices identically.

What to expect in the investigation

Ice melts and the same water can refreeze; freezing time varies. A cooled cooked egg remains cooked. Neither a before-photo alone nor an unobserved prediction proves reversal. Heating does not always create an irreversible change. Melting and refreezing together are the evidence.

Checkpoint question

Refreezing melted water demonstrates reversal. Reteach by following the same sample through all three stages.
