The Selfish Jean

It's an early morning record for the science siblings as they get in the episode recording before Ron disappears off with Agony Dad on a sailing trip.

This week they're exploring the replicating of DNA by metaphors of ladders and whatnot... and, would you believe it, it's actually a very good learning episode! Stuff goes in, Laura gets some things right and there are very few fallings out. Enjoy!
