Where Does the Puddle Go?

Observe and Question · Discovery approach

This is the chapter's opening unit, so orient students to the big idea: water keeps changing its form. Watch for the common belief that water simply soaks into solid surfaces — the steel plate observation is designed to challenge this, and students who still insist on seepage need a second look at the plate. A useful checkpoint: every group should be able to state at least one reason why seepage through a solid steel plate is unlikely before moving on.

0-8Teacher poses the puddle puzzle and students recall examples of water drying from surfaces around them.
8-22Groups observe water on a steel plate and confirm water does not seep through, then record their observations in a sketch.
22-35Students draw and label what they think happens to water on a drying cloth or mopped floor.
35-40Brief sharing of ideas across groups; teacher collects initial hypotheses without confirming or denying any.
Assessment

Competency (C-1.2). Description of physical changes in matter.

Learning outcome. Students can describe the observations that led to rejecting the seepage hypothesis and state that water changes between liquid and vapour states at room temperature.

A student places a cold glass tumbler filled with ice water on a dry table. After some time, water droplets appear on the outer surface of the tumbler. The student marks the water level inside the tumbler and waits. The water level inside does not drop. What does this evidence show?

  • A Melted ice escaped through tiny cracks in the glass.
  • B The glass absorbed moisture from the table surface.
  • C Water seeped through the glass from the inside.
  • D Water vapour from the surrounding air condensed on the cold surface.

D. Water vapour from the surrounding air condensed on the cold surface.

What each wrong option reveals

  • A Choosing this option indicates the student confused internal melting of ice with the source of the external droplets, ignoring the unchanged internal water level.
  • B Choosing this option indicates the student invented an external source not grounded in the chapter's evidence, suggesting the condensation mechanism has not been established.
  • C Choosing this option indicates the student holds the seepage misconception and has not used the water-level evidence to reject it.
