COLOMBIA & BEYOND: Last year, second graders became very excited about minerals and gems. As a result, we spent time learning which minerals come from South and Central America, and then painted rocks to create amethysts and lapis lazuli look-a-likes. Several filled little cups of water and dyed the water various shades with food coloring.
This year, students studied geodes in their regular classroom, but I learned about it a smidgen too late to tap into the unit. Maybe next year?!
