Teaching Tips

• These videos are a good length to interject into any lesson.
• This would be a good example of "how we know about ancient climates".
• This is a good piece about how scientists do their work and about the evidence scientists use to draw conclusions.

About the Content

• Ice cores and ocean sediments hold clues to our past climate.
• The first video provides the viewer with a comprehensive overview of using ice cores to analyze past climates and how scientists compare those climates to today's climate.
• The second video discusses how chemical information encoded in the shells of ancient ocean organisms are used to infer a record of ocean temperatures stretching back millions of years.
• Passed initial science review - expert science review pending.

About the Pedagogy

• These videos are part of a collection called NOVA: Decoding the Weather Machine (2018) which includes a lesson and additional videos. See https://www.pbslearningmedia.org/collection/nova-decoding-the-weather-machine/
• These videos could be used to support students as they learn about the various ways we study our climate system. Standards are identified in the resource.
• Teacher links are provided: https://pbslearningmedia.org/resource/nvdtwm-sci-climaterecord/interpreting-earths-climate-record-decoding-the-weather-machine/.
• These links identify science phenomena addressed, and provide guidance on building science practices using this resource.
• A list of questions to guide classroom discussion is provided.

Technical Details/Ease of Use

• There are annotations, including closed captioning, Spanish language, and transcripts available. There is a background document for educators, as well as Teaching Tips.
