Let’s Do Science
Re ga le du ca tio n
Let’s Do Science is based on the United States Next Generation n 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 books and places an emphasis on applying scientific knowledge dge e using stigations. ations. NGSS practices through numerous scientific investigations. tial element of Let’s Do Science sees engineering as an essential science education and as such is tightly integrated grated into both the textbooks and activity books. ude the follow fe The Let’s Do Science activity books include features:
