Invertebrate diversity tally

Student records data on poster of invertebrates.Students at Bailey’s Elementary School for the Arts and Sciences are finding out how many different kinds of invertebrates live in their schoolyard. Using a poster showing the invertebrates that are common in a Northern Virginia pollinator garden to familiarize themselves with these small animals, second-graders went out into the garden to see what they could find. They also used the poster to collect data. Every time they saw an animal such as a roly-poly or Monarch butterfly caterpillar, they put a tally mark on the laminated poster using a dry erase marker. The purpose of this activity was to notice how many kinds of invertebrates there are in a small garden, a diversity of life.

Students may come up with questions while searching. Teachers can record the students’ questions and later talk about how the class might find answers to the questions. Are any of the questions investigable, that is, can the students investigate to find answers or is that beyond their capabilities or the scope of a school year? Some questions can be researched in books, online, or by asking experts. Others can be answered with student data collection, analysis and discussion. One such question might be, “Will we always find roly-polies under the log?” How many days would your students have to collect data to feel that they had answered this question?
 Editor Linda Froschauer wrote in her column in the December 2010 Science & Children“Students have many questions, but in an inquiry setting they need to be taught how to formulate questions that will provide them with opportunities to investigate and ultimately develop understanding.” She says that students need ample time to explore a phenomenon before they can design questions that they can investigate.
