Multifaceted tool - some teacher creativity required.
I used this tool to teach about trends in mass extinction. See HHMI curriculum on their website. Also an excellent pool of data for teaching climate change.
How I Use It
It is a fabulous interactive with a wealth of data to explore and mine. Students can create a claim and support it with data. OR, you can create a claim and have the students support it with the data they collect. Covers from earth's creation to present day. Topics such as mass extinctions, climate change, and earth science supported.
