Worms – We Want to Know!

In class, we focus on inquiry science, which helps students view themselves as scientists while they are learning. They are active in investigations and explorations. Through this, students learn to communicate using a variety of methods.

We recently completed an investigation that took our students through the whole scientific method—from asking a question, to developing an experiment to answer that question, to communicating their results. Look at the pictures below to see what we did!clip_image004

Knowing that worms would be the next animals moving into our classroom, the students first brainstormed things we KNOW and WANT TO KNOW about worms. 

We did research and read many books about worms.  We found that some worms do live in dirt, like the worms we are used to seeing around our houses.  We also found that some worms can be found around trees, in the grass, on rocks, and even in the water!  They decided that the most important question, and the one that needed to be answered first, was “What do worms live in?” or “What will their habitat be?”  Students wanted to be sure they were prepared so the worms could live safely while we studied them.

The students used that data to create graphs combining the data from each table’s experiment box. Reading the graphs, students were able to determine the best habitat material for the worms in our class – dirt! We set up the habitat and the worms have lived there happily.

Below you can see pictures of the bulletin board we posted for our friends and parents to see and the vocabulary chart we made, which helped us talk about our work, and finally the story we wrote to communicate our study and the results.
