Crystal Cave On May 21st our class went on a field trip to Crystal Cave! Come check out all It took 2 hours, but we made it to the caves! On the bus we worked on a fun rocks & minerals activity packet! After we got off the bus we found our groups and went panning for gems! Then we watched a video about the facts and rules about the caves. Finally, we were in the caves and we explored many interesting rooms! I hope you found my Tackk interesting!
