Soil Life in Action: Bioturbation With and Without Soil Fauna

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.
