Bubble laboratory

Explore shape, colours, size and change with four illustrated questions. Choose one small observation with a grown-up; the screen examples are not measurements of your real bubbles.

THE GROWN-UP'S ROLE

Use age-appropriate ready-made bubble solution and a bubble wand; follow the product label. A grown-up holds and handles them. Keep liquid and wands away from mouths and eyes. No drinking straws, tasting or added chemicals are needed.

THE WHOLE GAME AT A GLANCE
  1. 1You can use only the drawings today. For a real trial, the grown-up prepares the space and a ready-made bubble kit.
  2. 2A guess is optional. Ask what the child actually noticed, rather than asking them to match the drawing.
  3. 3If you repeat, change just one thing where practical. A different result or a popped bubble is useful to notice.
WHAT THIS BUILDS

Making an optional guess, describing a detail and comparing it with an observation gives practice in careful looking and explaining an idea.

why it helps

Making an optional guess, describing a detail and comparing it with an observation gives practice in careful looking and explaining an idea.

make it fit your child

One game, three levels

Start where it feels comfortable and change the challenge whenever curiosity changes.

MAKE IT EASIER

You can use only the drawings today. For a real trial, the grown-up prepares the space and a ready-made bubble kit.

TRY A NEXT STEP

If you repeat, change just one thing where practical. A different result or a popped bubble is useful to notice.

small questions, real discoveries

Four ways to notice a bubble

One small observation can be a whole activity. These original drawings explain ideas; use the real activity only when a grown-up can prepare and stay beside the child.

  1. 01

    Choose one question

    You can use only the drawings today. For a real trial, the grown-up prepares the space and a ready-made bubble kit.

  2. 02

    Guess, notice, compare

    A guess is optional. Ask what the child actually noticed, rather than asking them to match the drawing.

  3. 03

    Try one small change

    If you repeat, change just one thing where practical. A different result or a popped bubble is useful to notice.

A frame or a free bubble?

Does the shape held by a frame have to be the shape of a free bubble?

A square wand containing a translucent flat film
Before we look

A square frame holds a flat soap film.

A square wand and a separate round bubble beside it
One illustrated example

A separate bubble is drawn beside the frame. It is rounded like a ball, not a flat paper circle.

Try it away from the screen

  1. The grown-up shows a film on a safe ready-made wand. A square wand is optional; one round wand is enough.
  2. They move the wand gently according to its instructions to release a bubble. The child does not need to blow.
  3. Compare the film still on the wand with a bubble that has left it. Point, describe or pass.

A question to share: What was still attached to the frame, and what floated away?

For grown-ups: a little science

A frame holds a film’s boundary. A free bubble tends toward a sphere; moving air or contact can deform it.

Colours without paint

What might change while we look at a bubble?

A round bubble with pink, blue and yellow patches
Before we look

A bubble is drawn with a few coloured patches.

A similar bubble with different coloured patches
One illustrated example

The same-size bubble has a different arrangement of colours. Real colours need not match this drawing.

Try it away from the screen

  1. The grown-up makes a bubble in ordinary daylight or room light, away from faces.
  2. Choose one colour or bright patch to follow while the bubble remains visible. No stopwatch is needed.
  3. If nothing colourful is visible, say so. Try another viewing position together, or finish with that observation.

A question to share: Which colour did you actually see, if any?

For grown-ups: a little science

Reflections from a film’s two surfaces interfere. Film thickness and viewing conditions affect the colours; they are not added paint.

Small and large

Could two bubbles be different sizes and still have something in common?

One small bubble and one large bubble
Before we look

Two bubbles are drawn beside one another at different sizes.

Small and large bubbles with dotted rounded outlines
One illustrated example

Dotted outlines help compare their rounded shapes. The drawing does not measure real bubbles.

Try it away from the screen

  1. The grown-up makes a few bubbles; making particular sizes is not required.
  2. Look for two that seem different in size. If they do not appear, compare the drawings instead.
  3. Describe one similarity and one difference. Do not rank bubbles as better or worse.

A question to share: What looks alike, and what looks different?

For grown-ups: a little science

A sphere encloses a given volume with the least surface area. Free bubbles can be different sizes and still be roughly spherical.

When a bubble disappears

What could we notice if a bubble pops before we finish looking?

One intact round bubble
Before we look

One whole bubble is drawn above an empty space.

A dotted broken outline where the bubble had been
One illustrated example

A broken dotted outline marks where it was. This is a drawing, not a countdown or a promise about when bubbles pop.

Try it away from the screen

  1. Watch one bubble from a comfortable distance. There is no need to chase, touch or burst it.
  2. If it disappears, tell each other what you saw before and afterwards. One observation is enough.
  3. The grown-up can make another bubble if the child wants. A popped bubble does not mean anyone failed.

A question to share: What did you notice just before it disappeared?

For grown-ups: a little science

A bubble’s thin liquid film can break. Water loss and surrounding conditions affect its life; this drawing does not predict a duration.

Three questions worth waiting for

Tap a question for a gentle follow-up. Ask just one, then leave room for the child's own idea.

NOTICEWhat did you think might happen, and what did you really notice?

Pause and wait. A child may need several quiet seconds.

COMPAREWhat changed after your try?

Ask: “What helped you notice that?”

IMAGINEWhat would you like to test next?

Let the child choose one small change for the next try.

Choose one question — there is no need to ask all three.
