Elinor Wonders Why
This report covers the full series. Elinor Wonders Why is a gentle, science-forward PBS Kids preschool show in which Elinor the bunny rabbit and her friends explore nature, ask questions, and figure out how the world works together. Across two seasons and 63 episodes, there is nothing scary, upsetting, or inappropriate for even the youngest viewers.
A wonderful fit from around age 3 and up, and genuinely enjoyable for curious kids well into early elementary.
