Let’s Do Science Let’s Do Science is based on the United States Next Generation Science Standards (NGSS). The series consists of full-color textbooks and full-color activity books for Grades K to 6.

Let’s Do Science engages students with a highly visual presentation of the disciplinary core ideas in the textbooks and places an emphasis on applying scientific knowledge using NGSS practices through numerous scientific investigations.

Let’s Do Science sees engineering as an essential element of science education and as such is tightly integrated into both the textbooks and activity books.

The Let’s Do Science activity books include the follow features:
