November 25, 2009 Day 10 Classroom observations with Grandfriends

Today was Grandfriends Day. Kindergartners continued working on their observations of the caterpillars in our classroom and viewed the photographs posted from the ISS last evening. Our caterpillars are growing and are fairly still today even though the classroom is warm and their food is still available in the food boxes in the rearing chambers.

In space, the caterpillars have begun to pupate. In photos, the pupas look greenish. Each caterpillar positioned itself at a different place, curling up like a letter "C" before shedding it's skin for the very last time. On earth, caterpillars hang toward the ground in a letter "J." One pupa is detatched and floating in the box. On earth if this happens, the pupa falls to the ground. In space, the pupa floats. Still floating in the box is a lot of frass!
