BioSleuths Aurora: Soil Life
Whether you can see them or not there are many things living in the soil. This is one of the concepts your student learned today. Students set up two experiments today to learn not only about where life comes from but also what kinds of organisms live in the soil. Students worked in groups to prepare their first experiment. They placed pieces of chicken in cans with different coverings; they will come back to these cans later in the week to observe what is new. After this experiment they collected soil samples to learn about all the living things inside of it. Many of the students found worms or other critters while they were on this mission.
These curious biosleuths shined light directly over the Burlese-Tullgren funnel to help them understand what organisms live in the ground. “I think I’m going to find more worms in my soil.” hypothesized one of the sleuths.
Ask your student:
How did the light help you find organisms in the Burlese-Tullgren funnel set up? (organisms will tend to move away from the light/heat source, which is downward into the alcohol).
