I’m an amateur geologist who sometimes gives presentations to kids. They love it - lightning glass, dinosaur poo, volcanoes etc… Only now I’m after some ideas to make them think and then groan - Puns of course.
Remember that these are for kiddies so be gneiss:D
“I’m a geologist; I’ll make your bedrock.”
“tuff schist”
“San Andreas is not my fault.”
“Bring more Geology to Missouri–subduct Kansas.”
“Paleologists…helping geologists look cool since 1822.”
“Did you hear about the unethical glaciologist having his hand in the till?”
“Pyrites of the Caribbean”
“Geologists have their faults.”
“Schist happens.”
“Tell her to have a gneiss day.”
“Whatever you do, don’t take him for granite.”
“May the quartz be with you!”
Fulgurites, coprolites, pahoehoe and aa. Jagged aa is the one that were you to walk barefoot on it you’d say “Ah ah ah ah…” Tell them about gastroliths too, stomach acid-etched round stones dinosaurs swallowed to aid with digestion much like how dove and some other birds eat gravel to help with theirs.
Kids, eh? The youngest on top is a superposition! When’s the best time to buy bullets? On ammonite!
