Curriculum

• Two clean sponge pieces, with one reserved fresh and dry for the challenge
• Three shallow plates
• Small cup of water and measuring teaspoon
• Paper towel
• Small sheet of foil
• Adult scissors used only before the child joins
• Dry towel
• Paper and crayon

1. Step 1. Place one teaspoon of water on the shallow plate with a dry towel nearby. Ask, “What if the sponge touches the water?” and let your child wonder aloud about possibilities.
2. Step 2. Offer the hypothesis frame “I think the sponge will ___ because ___.” Introduce absorb: “Absorb means soak up a liquid.” Ask your child to try absorb in the hypothesis.
3. Step 3. Touch the sponge to the water and talk about what happened. Ask what clues support or change the first idea.
4. Step 4. Invite imagination: “Imagine the sponge were as big as a bed. What might it absorb?” Let your child explore more than one possibility aloud.
5. Step 5. Talk first before drawing or writing. Ask your child to say the final idea aloud, then draw it; the parent may write the child’s exact words beside the drawing.
6. Quick check. Give the dry paper towel and foil separate plates with a fresh one-teaspoon portion of water on each. Before testing, ask for a “What if…?” possibility and an “I think ___ because ___” hypothesis about which will absorb water. Test both, then ask, “Imagine the paper towel were as big as a blanket. What might it absorb?” Success means your child uses absorb accurately, explores the imagined possibility aloud, talks through the result, and only then draws or dictates what happened.

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.
