A little about this puzzle

Inside a transparent wind tunnel at a science center, one paper plane rests on a continuous clamp, support rod and base. A goggled adult adjusts an external control while a child holds a stopwatch and points toward the wing. Recording tools lie on the foreground table, with a paper clip attached to a notebook page. The color page presents the full scene, the outline page provides searching and coloring space, and the answer page colors the intended targets and matching key icons. Chinese and English editions share the same artwork. ## Image descriptions Choose the Color or Line art image, use the picture clues to find each object, and keep the Answer key separate until you are ready to check. The three images can be printed or saved as PDF using your browser.

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.
