In this video, Steven Allison describes the fascinating abilities of microbes to help plants survive, recycle wastes, produce oxygen, and survive extreme environments.
Steven explains that Earth's soil microbiome can help us adapt to climate change, build carbon in the soil, and fight food insecurity.
Teaching Tips
Positives
This video is a broad introduction to microorganisms with specific connections to climate change.
Additional resources that would be helpful for further research are listed under "Steven Allison's resource list" towards the bottom of the page.
Additional Prerequisites
Students should be familiar with cells, microbes, and microbial communities.
The video can be downloaded as an MP4 and used offline.
Differentiation
The video is somewhat long and full of information about microbes. In order to help students process the information, a graphic organizer or vocabulary list is recommended.
Biology classes could use this resource to introduce decomposition, the diversity of life, evolution, natural selection, nutrient cycling, or natural solutions to climate change.
It could be helpful to pause the video at various points to do comprehension checks and have students work in groups to write a summary of the video.
This 10-minute TEDx talk presents examples of new scientific discoveries related to climate change and microbiology. After introducing some basic microbiology descriptions, scientific experiments that have helped us understand the impact of climate change on microbiomes is presented, followed by some innovative ways to use microbes to address climate change. This resource is recommended for teaching.
Standards
English Language Arts
Speaking & Listening (K-12)
11-12.SL.2 Integrate multiple sources of information presented in diverse formats and media in order to make informed decisions and solve problems, evaluating the credibility and accuracy of each source and noting any discrepancies among the data.
Science
LS2: Ecosystems: Interactions, Energy, and Dynamics
HS.LS2.3 Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
HS.LS2.5 Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
LS3: Heredity: Inheritance and Variation of Traits
HS.LS3.1 Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
LS4: Biological Evolution: Unity and Diversity
HS.LS4.4 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
HS.LS4.5 Evaluate the evidence supporting claims that changes in environmental conditions may result in (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
