Butterfly pen stand making activity by STEM World School students. Butterflies are one of the most beautiful and colourful creatures found in nature. Their brightly-coloured wings attract everyone. The students of Class 2 in STEM World School are learning about the life cycle of a butterfly and its various stages which is equally fascinating. To add an essence of beauty and charm with this life cycle of a butterfly, the students of STEM World School have crafted their concept in an innovative manner. They have related their concept with a butterfly pen stand which is a beauty in itself as we all know that a pen stand is an item of utility as it is used to store pens, pencils or other small stationary items.
