American Museum of Natural History

This video illustrates the environmental challenges and achievements since Earth Day was established in 1970. It can be used as an extension or engagement resource. However, it would need to be carefully framed with the objectives of the lesson.

Video length is 3:57 min

Teaching Tips

  • This video would provide a good base for discussion around the many environmental topics addressed. If framed carefully, the video can help motivate students to engage with environmental issues.

About the Science

  • This video summarizes some of the environmental challenges faced and progress made in the period between Earth Day 1970 and Earth Day 2017. Some ambiguity exists in the science content. For example, the reference to clean cars only means that particulate pollution has been addressed. However, that might imply to students that climate change has been addressed (which is not the case and is a critical concept to grasp). Similarly while bald eagles have made a comeback, many more species are becoming extinct. Hence, if this video is used as a resource, the teacher will have to critically discuss the content presented in the video.
  • Comments from expert scientist:
    Scientific strengths:
    Great resource.
    - Shows the negative ways in which our planet has changed over the past 30 years including, population increase, CO2 emission increase leading to temperature increase, sea level rise increase, water usage increase, animal population decreases
    - Also shows the positive ways in which things have changed after signing The Clean Air Act in 1970 (cleaner vehicle emissions, recovered species, more jobs created, a stabilizing ozone layer, etc.)
    Suggestions:
    Should be noted that these numbers will definitely change in the future years to come.

About the Pedagogy

  • The video is comprised of simple graphics that clearly illustrate key points and flow through connected concepts.
  • The video can be paused to offer opportunities for discussion.
  • Students may feel emotionally depressed after watching this video. For that purpose, the teacher needs to be attentive towards the framing of this resource (when they use it and how they use it).

Technical Details/Ease of Use

  • This short video can be easily viewed online.
  • Video transcript is available.
  • The video is not narrated and words go by very fast. However, by changing the settings on the youtube video, one can slow the speed from normal to 0.75 or 0.25 which slows the video.
  • Some details are tiny and appear at the very bottom of the screen, so the teacher will have to draw students' attention towards them.

Next Generation Science Standards See how this Video supports:

Middle School

Disciplinary Core Ideas: 2

MS-ESS3.C1:Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But changes to Earth’s environments can have different impacts (negative and positive) for different living things.

MS-ESS3.C2:Typically as human populations and per-capita consumption of natural resources increase, so do the negative impacts on Earth unless the activities and technologies involved are engineered otherwise.

Cross Cutting Concepts: 1

Stability and Change

MS-C7.2: Small changes in one part of a system might cause large changes in another part.

High School

Disciplinary Core Ideas: 5

HS-ESS3.C1:The sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources.

HS-ESS3.C2:Scientists and engineers can make major contributions by developing technologies that produce less pollution and waste and that preclude ecosystem degradation.

HS-LS2.C2:Moreover, anthropogenic changes (induced by human activity) in the environment—including habitat destruction, pollution, introduction of invasive species, overexploitation, and climate change—can disrupt an ecosystem and threaten the survival of some species.

HS-LS4.D1:Humans depend on the living world for the resources and other benefits provided by biodiversity. But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change. Thus sustaining biodiversity so that ecosystem functioning and productivity are maintained is essential to supporting and enhancing life on Earth. Sustaining biodiversity also aids humanity by preserving landscapes of recreational or inspirational value.

HS-LS4.D2:Biodiversity is increased by the formation of new species (speciation) and decreased by the loss of species (extinction).

Cross Cutting Concepts: 1

Stability and Change

HS-C7.1:Much of science deals with constructing explanations of how things change and how they remain stable.
