Product Description
In this activity, students make a time-line depicting the 5 mass extinctions plus the 6th on-going mass extinction today. Hopefully, they will make the connection between today's beginning of a mass extinction due to man's interference. The NGSS standard HS-LS2-6, 7 want students to understand the role humans are playing in their environment, leading to a decrease in biodiversity. DCI's LS2.C and LS4.D contain this information.
