"What Lives in Soil?": A Grade 3 Inquiry

It is early, before the national anthem, when the workshop lady comes in and quickly turns our classroom into a totally different place. The anthem ends in a few minutes and the lady starts to introduce herself to the class. “My name is Erin,” and she starts to talk about what we are going to do and asks us some questions like, “What lives in soil?” We do say some things that live in the soil but not all of them, so one of our missions is to find out what else lives in the soil.
After Erin finishes talking it is time to go to the different stations. For each station you do something different. For example, you might need to do some kind of experiment and fill out a sheet. For every station we learn something new: what kind of nutrients plants need, what the horizons of soil look like and how big the soil molecules are, how worms help soil (which includes touching worms!) and how erosion happens and how to prevent it.
As the stations are all completed, we meet again to discuss the answers to the questions she asked at the beginning of her presentation. Then she demonstrates with an apple how little good soil there is left on our planet. Sadly, the workshop has to end and Erin leaves. This workshop might have been the best thing we did in our soil unit!
