Think Like a Scientist Four activity books · ages 3 to 6
Light Minds Lab

28 free printable pages.

Every sheet below is a real page from one of the finished books, printed to the same 8.5 × 11 inch letter size. No email address, no signup, no watermark across the middle.

Printing them

Print at 100%, not "fit to page".

The sheets are laid out at US Letter with a half-inch safe margin, and the corridor widths and target sizes on them are chosen for a specific age of hand. Scaling shrinks those. In the print dialog choose Actual size or Scale: 100%.

Black-and-white or grayscale is fine, because the pages have no color in them. Plain copier paper works too. The lines are heavy enough that nothing drops out on a home printer.
