Conductivity+Tests

The Conductivity test group did experiments to see if the soil had the energy to light a lightbulb. They found that some of the soil did not have enough energy to light the bulb. However, they did find some soil with enough energy to light the lightbulb .The materials they used to do this were different types of soils in different horizons, a battery in a battery holder, a tiny red light bulb hooked up to the battery holder, and a tiny bottle of condensed water.They used a drop of condensed water on the soil and hooked the wires to the soil. But the group learned a lot and had fun.
