The lesson I chose is from The School District of Philadelphia's Curriculum & Instruction's website.

Click on science, click grades 7&8, go to the right &
click on MSP Companions. You will see a list of 7th &8th grade
topics per report card period. I chose 8th grade-2nd report card
-Inside the Restless Earth. Click this & look for Learning
Resources/ Extension Activities. The activity is called Sequencing Time
& the goal of this lesson is for the students to understand the
necessity and the processes of placing events in sequence.
