Earth science lab relative dating 2

This page is a regularly updated plan for 8th-grade science classes.

The Keyword(s) and Warm-up are completed during the first five to ten minutes of class.

This matching process is called correlation, which has been an important process in constructing geological timescales.

Some fossils, called index fossils, are particularly useful in correlating rocks.

Additionally, if you would like all of the resources together in a PDF document, that can be accessed as a complete resource here: Dating & Rock Layering [Entire Lesson][PDF].

Finally, students may need their Earth Science Reference Tables [ESRT] for parts of the lesson (a document used widely in the New York State Earth Science Regents course) as well.] This is the first, and one of the most important, lessons in the new unit.

After time expires (anywhere from 2-4 minutes depending on the type of Do Now and number of questions), we collectively go over the responses (usually involving a series of cold calls and/or volunteers), before I call on a student and ask them to read the objective out loud to start the lesson.

Plus, get practice tests, quizzes, and personalized coaching to help you succeed.

The lesson starts with a brief introduction into dating techniques, eventually flowing into a distinction between relative and absolute dating (which will be discussed again later in the unit).

They then see some new vocabulary and get to practice applying it before closing out for the day.
