Problem description
For phetsims/qa#871
On the third screen. The temperature displayed starts much lower than it does on other screens, and then rapidly jumps to a more reasonable number as soon as a photon hits the ground. This looks very odd to me and I'm wondering if it is intentional.

This is intentional, but a good observation. @arouinfar will add a note to the teach tips about it. The reason for the lower value in the third screen is that with a high albedo and a low solar input, the temperature can get much lower on this screen, and we start each screen at the lowest temperature and allow them to heat up from there.

I'll close this issue and @arouinfar will follow up in the teacher tips.
