There is a great box hidden in one of the Acorn Room cupboards that hold inside samples of sand from all over California. It is a mysterious and wonderful box full of crystals and rainbows (especially with a microscope). In fact, check out these crystals:This was taken through the lens of an Acorn Room microscope. Look at that rainbow! Look at those crystals! Grade 2 students investigated this question today: Do sands from different places look different? But our sands are only from California. That is why I am “Calling all Sands!” With all the globetrotting the Trinity community participates in we could establish a worldly collection of sands to study.
If you are traveling to any part of the world where there is sand, to any beach by the ocean, or beach by a lake, or even a beach by a river, bring a sample of your sand back in a small labeled container and deliver to the Acorn Room. Spread the word!
