On a cloudy Friday morning, the first graders at North Buncombe Elementary School had their routine classroom experience transformed into a hands-on science lab, thanks to a visit from local soil expert Jen Knight.
Knight, who works with Environmental Educators from Buncombe County Soil and Water Conservation, brought an array of soil samples to the school, giving the students a tactile and interactive lesson in soil science. The activity was designed to teach them about different types of soil, along with their specific characteristics such as porosity and permeability.
Students eagerly dug their hands into various samples, feeling the difference between sandy, clayey, and loamy soils. They learned how each type of soil affects water flow and plant growth, key concepts in understanding environmental sustainability.
In addition to soil types, Knight introduced the students to the small organisms that play a crucial role in soil health. She brought along a collection of insects, including various beetles and a millipede, allowing the students to touch and observe these creatures up close.
“The insects and millipedes aren’t just cool to look at,” explained Knight. “They help break down organic matter and enrich the soil.”
The students, some timid and others enthusiastic, took turns observing and gently holding the various insects.
First grade teacher Pamela Lewis expressed her support for the interactive learning experience.
“This activity provided our first grade students an opportunity to have meaningful, hands-on learning that supports what they have been learning in the classroom about soil,” she said. “And it goes along with our rocks/soil science standard.”
The hands-on learning experience was not only about touching and observing but also about appreciating the biodiversity beneath our feet and understanding its significance to our world.
