Worked example. “What if the sponge touches the puddle? I think it will absorb the water because a sponge has tiny spaces that soak liquid up. I imagine a giant sponge could absorb a bathtub of water.” Say the idea before drawing it.

Optional challenge. Before the child joins, the adult prepares equal-size fresh dry samples of the reserved sponge, paper towel, and foil and puts the scissors away. Put each on a separate dry plate and use the measuring teaspoon tip to place five equal-size drops of water in the center of each. Wait ten seconds without moving the samples, then compare whether the water soaked in or remained as beads or a puddle. State only what happened in this trial rather than ranking each material in general. Explain and revise the hypothesis. Use waterproof accurately: a waterproof material does not let water pass through.

What to notice. Save a short parent note quoting one “What if…?” possibility, one “I think…because…” hypothesis, one accurate use of absorb, one imagined possibility, and confirmation that the child talked first before drawing or dictating. A photo may show the materials or drawing without the child.
