“Why are there so many different kinds of rocks?” “Why can’t you see the wind?” “Why does it rain?” “Why, why, why?” Anyone who has spent any time with little kids knows that their inquisitiveness knows no bounds. The best part is exploring together the answers to questions that make you both wonder. Remember, you don’t need to have all the answers. It’s okay to say, “I don’t know. Let’s look for the answer together.” The latest batch of NSTA Kids I Wonder Why books focus on Earth science. Written for K–6 graders, these titles can provide your students or children with answers to many of their questions while stimulating their curiosity even further.
