A little about this puzzle

At a wetland science museum, a student pours cloudy observation water from a jug into a fixed transparent filter. A guide points toward the collection cup directly below the outlet. Sand and gravel layers rest above a supporting mesh. A filter-layer diagram card, magnifier and clear ruler lie on the side table. The right cabinet holds a curved sand scoop, coarse-stone sample box and notebook; a sand-sieving funnel and pencil pouch rest on the rear bench. Ten clues form two rows.

Make it your own

Use the three-page print layout: Color on page 1, Line art on page 2 and Answer key on page 3. Choose your printer or Save as PDF in the print dialog. For A4 paper, choose Fit to page.
