Mystery Doug
210 episodes
Every episode opens with a question a real child asked, and Doug spends four to eight minutes chasing the answer with evidence. Are mermaids real? No, but sailors long ago probably spotted manatees and let imagination finish the job. Can animals get sunburned? Yes, though fur, feathers, and mud work as sunscreen. Can a mountain become a volcano, can animals laugh, do animals really predict the weather. The answer is often no, which is half the value. Kids watch how you find out rather than collecting a fact. Made to open a science block or start an argument the class can settle later.
