Cave Unit: Day 8

This is part one of a Caves Unit Study intended to be done before (or after) visiting Inner Space Caverns or another cave.  

Day 8:  Sections 10 - 11
When Water Moves:  Pg 28 - 30
Keeping Caves Alive:  Pg 30 - 33

1.  Read Sections 10.

Discussion question:

  • What special features do water animals and fish in caves have?  What things do they NOT need that animals that live outside a cave usually need?


Texas Cave Salamander
The Texas Cave Salamander is considered to be the most cave adapted salamander in the world.   It is found in Ezell's Cave in San Marco (an underwater cave that is part of the Edwards Aquifer).  See two great videos of it below...

Texas Cave Salamander Video 1 (short informative video)
Texas Cave Salamander Video 2  (longer video of it swimming...I started the video midway, because it takes a long time to get to the salamander, though there's some pretty cave diving shots earlier.)   


2.   Read Section 11 (skip sidebars until afterwards)
Discussion question:

  • What can we do to help keep caves and the animals in them from being harmed?
  • Have your child try to find all the silhouetted items in the cave pictures on pg 31 and 33.  


1.  SIDEBAR:  Cave in a Box - Pg 30

2.  SIDEBAR:  When the Wind Blows/Tell from Spel - Pg 32
While you aren't in a cave, you can try this in various rooms in your house (maybe open a window or two to make the airflow greater).  Read the "Tel from Spel" section.)

2.  Junior Cavers Workbook page 22  (NOTE:  This page mentions "karst," which is not covered in One Small Square Cave, but is covered in the Junior Cavers Workbook on page 19-21.  I've set aside an extra section for KARST which can be done before this section, or afterwards...but it does leave that vocab word hanging if you don't do pg 19-21 first.
