Age of the Earth & Geologic Time Scale Complete Unit

Age of The Earth and Geologic Time Scale

Do you need a little help teaching your middle school science class about the age of the Earth and the geologic time scale? Students will also like Analyzing the Fossil Record.

This is a

Age of Earth Foldables

This unit includes an informative 22-slide PowerPoint presentation on the methods scientists use to find Earth’s age. This is how I start the unit.

Keep your students accountable with scaffolded notes that accompany the PowerPoint:

Next, I challenge students with three pages of nonfiction text passages with comprehension questions:

Students will construct an explanation based on evidence from rock strata and the fossil record to explain the geologic time scale and age of the Earth.

This unit is aligned with MS-ESS1-4. Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth’s 4.6-billion-year-old history.

Make an argument from evidence for how the geologic time scale shows the age and history of Earth. Emphasize scientific evidence from rock strata, the fossil record, and the principles of relative dating such as superposition, uniformitarianism, and recognizing unconformities.

Students will use mathematics and computational thinking to make a scaled-down timeline of the major events in Earth’s history… Along the same lines, students will enjoy learning about Pangea.

…and they will construct scientific explanations on the age of the Earth:

This complete unit ends with a two-page assessment in the format similar to the end of the year testing:

This resource also includes foldables that are perfect for your interactive science notebook:

And a blank foldable if you want to use your own vocabulary words:

Answer keys are included for EVERYTHING!
