“ROCK HUNT JIGSAW ACTIVITY” LESSON PLAN

THREE KINDS OF ROCKS

Sedimentary Igneous Metamorphic

SEDIMENTARY ROCKS

Rock that has formed from sediment, like sand, mud, and small pieces of rock.

Over time, these materials are compressed to form rock.

Examples include sandstone and shale

IGNEOUS ROCKS

Igneous rocks are formed from the lava that erupts from volcanoes, but can form underground as well

This lava eventually cools and forms a rock

Some examples are pumice, granite, and obsidian

METAMORPHIC ROCKS

Commonly known as ‘changing rocks’ because they change from one form to another

Changes can result from heat, pressure, and chemicals.

Examples include marble and slate

ON TO THE LESSON…

This lesson will give the learners the opportunity to be the experts

The students will form five groups of three people. Each person in the group will get a number (1-sedimentary, 2-igneous, or 3-metamorphic).

All the 1’s, 2’s, and 3’s will work together to find information about their type of rock.

CONTINUING THE LESSON…

Students will use this website to gather information in their expert groups. They will follow instructions on the site to complete the activity.

Students will go back to their original group and present their findings to their peers.

HAVE FUN!

I can’t wait to see what you come up with!
