This week Laura Lexx is back in the Physics Lab and oh boy is she furious about it! As her brother Ron attempts once again to get over his own disinterest in science and get her to concentrate, they have a look at energy transfers and how to calculate how much energy is used in heating and cooling objects.

Laura gets promised tea that never comes, but helpfully she does now know how much energy her kettle is using to make this hypothetical tea that never comes. Via a picnic at Tarr Steps, Ron teaches Laura about cooling down as well and they argue over whether formulas are useful or not. It’s one of their angrier episodes so you best enjoy it, because they didn’t.
