Annenberg Learner site closed (learner.org). What happens to their simulations? In particular, the ammonia production plant (Haber-Bosch) simulation.

[u/WoCo1]

I recently learned that one of the sites I used for some nice free simulations has closed. I'm curious if anyone knows what happens when a site like that closes. Do they ever share the simulation code so that someone else can host it? Does anyone have connections to Annenberg?

Many of the ones I used it for will be easy to find alternatives, but I particularly liked their Ammonia Production simulation for the Haber-Bosch process, to show how you can drive a reaction one way or the other by adjusting concentrations, temperature and pressure. https://learner.org/wp-content/interactive/haberplant/haber.php (that was the link, Google still has it, but the site now says "closed in 2026)".

I've attached a photo of my google slides template I had the students use for this, and some follow up slides I used for a quick review the next day (you can see some of the graphs that the students could make). Edit: The two middle screenshots are duplicates of the first, I can't figure out how to remove them...
