Synopsis
- This time-lapse video demonstrates the difference between soils with and without invertebrate decomposers.
- Two additional videos and a brief article show and describe how invertebrates accelerate decomposition and why bioturbation is important for soil fertility.
- Bioturbation increases nutrients for plants, aerates the soil, allows for better water infiltration, and improves biodiversity and soil quality.

Teaching Materials
Positives
- The absence of narration provides an excellent opportunity for students to describe the phenomenon they observe.
- The speed of the video can be adjusted to slow it down or speed it up, which may be helpful.
Additional Prerequisites
- Students should be familiar with the concept of decomposition.
Differentiation
- Since there is no audio, have students describe what they think they are observing during the first viewing of the video.
- Have students draw a diagram or picture to define what they think bioturbation is after the first viewing of the video.
- Students could investigate composting on their own or set up a composting bin/area as a class to more deeply understand the content.
- Have students describe the fungi that is decomposing leaf litter in the non-flora chamber and then show students this video about how fungi are vital to plants and this video and article about the importance of fungi for adapting to climate change.
