Question: How accurate are the science lessons on the show?
Answer: In general, quite accurate as that was the point of the show. To teach kids about science. As the show is now over 20 years old, some facts have changed as we're always discovering new things. For the time, it was as accurate as it could and much of it is still accurate now.
One thing I think the show gets wrong is the idea that electrons stop moving when you break a circuit. Electrons never stop moving.
