DOWNLOAD, PRINT & LEARN

These sink float and capacity worksheets separate water support, paper-cargo placement and container holding amounts rather than treating them as one test.

DIGITAL PDF DOWNLOAD — NO PHYSICAL ITEM.

This collection contains the same PDFs offered individually and may repeat files from other bundles. No new or exclusive manuscripts are included. Check exact component titles before buying overlapping products.

Exactly what is included

  • Sink, Float and Test Again — 20 pages (child-facing practice with adult support)
  • Paper Boat Cargo Challenge — 24 pages (child-facing practice with adult support)
  • Capacity, Pour and Record — 25 pages (child-facing practice with adult support)

3 separate PDFs; 69 total pages, including covers and guidance—not 69 separate activities.

A practical way to use the collection

Use supplied paper cases to distinguish three questions; optional adult-managed observations follow the separate instructions in each guide.

Choose a comfortable starting point

Common adult-supported range: ages 7–8. Individual guides suggest ages 5–8, 7–10 and 6–9. Every practical water setup requires active adult management; the paper-only route is complete.

Important differences and limits

Paper Boat Cargo Challenge uses a large preformed paper bowl, not origami instructions, with at most two large folded whole-paper cargo pieces. Capacity is a defined holding amount, not a safe cargo rating. Floating, staying upright and keeping cargo dry are different observations. Optional practical work requires continuous adult supervision, a shallow stable unbreakable tray and each guide’s suitability checks; adults alone pour. No small or heavy weights, glass, drinking or electrical proximity. Stop on wetting, tipping, bottom or side contact or uncertainty; never deepen water to force a result. Empty and dry immediately. No water, supplies, boat certification or guaranteed result is included.

Print and use

English-language US Letter printable, non-fillable PDFs. Follow each component’s print and use instructions. No app or A4 edition. Use your own suitable printing, paper and materials. This separate collection is not the free 15-book family bonus. No guaranteed learning outcome.

Household use

For the purchasing household. Do not redistribute, publicly upload or resell. Contact Wonder Kids Toy for broader use.
