September 2, 2014--First Day of School

What an exciting first day of school! Our STEM specialist introduced the students to silk moth eggs which are beginning to hatch. There are 50 eggs in that tiny petrie dish you see in the photograph above. Some eggs are still intact, but many began to hatch as we watched. The students measured the larvae and found out that the caterpillars were 1/2 centimeter long at birth. We will watch these caterpillars grow for the next month until they become as long as 10 centimeters (4 inches). The caterpillars are picky eaters who only consume mulberry leaves. Fortunately, two wonderful parents who have mulberry trees in their gardens are supplying us with leaves. Stay posted!
