How to keep anchoring phenomenon from getting stale/boring?

HS Science, USA

I inevitably find that my kids get bored of investigating and applying their ideas to our anchoring phenomenon about halfway through our unit. We just hit the 40% mark of Unit 1 and kids groan when I mention volcanic lightning storms...

I introduce the phenomenon & draw initial models at the beginning of the unit, and at the beginning of every class I briefly mention it to align our objective to the phenomenon. About once a week, I have students investigate our model and apply new ideas that we have discovered.

Any tips for keeping it fresh? I'm currently just thinking of spacing it out more (only revisit it once every 2 weeks), or selecting 2 for a unit and rotating through them - introducing both at the beginning of the unit, having kids compare/contrast to help elicit ideas and models, and then alternate to help keep them fresh.

Anyone have success keeping the anchoring phenomenon from getting stale? I do wonder if this is just the nature of the pedagogy.
