Teacher Rosemary Rehill shares her experiences with STC's Life Cycle of Butterflies kit in her own words.

Back in May 2002, my class of second graders at Copper Beech Elementary School studied STC's butterfly kit. Throughout the unit, the students were totally enthralled in observing and studying each stage of the butterfly's development. In past years, excessive heat has made the timing of events difficult to correlate with the lessons, but this year a move into a new school with air conditioning made the unit considerably easier to work with.

Caterpillar garden in an aquarium. When the live shipment of caterpillars finally arrived, there was tremendous excitement. The children had been eagerly awaiting and anticipating them. We had talked extensively about what we expected to see. I had recorded their predictions on chart paper and displayed it. This year we were delighted to receive a double batch of caterpillars so we had far more than we usually have. There was a bit of a dilemma to know what to do with the all the additional caterpillars as we were only given four butterfly boxes. A colleague suggested that we set up a caterpillar garden in an old fish aquarium and this seemed to work well. The addition of masking tape around the top screen prevented any caterpillar escaping and the clear glass made it much easier for the children to watch the caterpillar's daily development.

Looking at the chrysalis stage. Each day the students would rush over to check on the caterpillars changing development. There was tremendous excitement the morning when they discovered that virtually all their caterpillars had changed into the chrysalis stage overnight. I always left plenty of magnifying glasses by the tank so that they could look at them whenever they wanted to. The glass tank certainly made viewing easier than the small plastic cups that are provided in the kit.

Discussing the chrysalis. I took the chrysalis from the individual plastic cups and gently taped them inside the butterfly boxes. Before we put the lids on the boxes, I allowed the students to observe them really closely. Prior to the observation we had discussed what parts of the developing butterfly we might see in the chrysalis.

Students watch for changes. I constantly challenged the students to look closer and to predict when and how the butterflies might emerge. The twitching of the chrysalis fascinated my students and generated a lot of questions.

Recording in the butterfly journals. While we waited for our butterflies to emerge, the children worked on daily recordings of their observations in their butterfly journals. Much of their work involved coloring and cutting, which constantly reinforced the butterfly cycle.

Working on the butterfly wheels. In one lesson, the children made butterfly wheels. This involved cutting out and pasting the various stages of the butterfly. As their work progressed, I questioned them about each picture. I was able to gain valuable insights into the depths of their understanding and this was a help for me during assessment.

What will happen next?
