It is always a great day when you get to explore caves with 5th graders from Greenwood Elementary. We hiked up to Timpanogos Cave and learned about the 6 ingredients needed to make a cave: 

Limestone

Water

Calcite

A Fault Line

Minerals (for color in the cave)

Time

I was so impressed with the students' ability to look at the evidence the ranger pointed out and from that they were able to come up with what scientists think is happening in the cave.
