WHAT LAYER OF EARTH IS EACH LETTER IDENTIFYING

WHAT LAYER OF EARTH IS EACH LETTER IDENTIFYING? BELLWORK 10 -13 -16

OBJECTIVES • STUDENTS WILL BE ABLE TO IDENTIFY HOW THE EARTH IS AFFECTED BY LONG- TERM AND SHORT- TERM GEOLOGICAL CYCLES AND THE INFLUENCE OF MAN. • SPI 7. 7. 4 DIFFERENTIATE AMONG THE CHARACTERISTICS OF THE EARTH’S THREE LAYERS. • SUCCESS CRITERIA: I CAN IDENTIFY AND DESCRIBE EARTH'S LAYERS.

GALLERY WALK • YOU WILL HAVE 4 MINUTES AT EACH POSTER. YOU NEED TO WRITE THE NOTES FOR EACH LAYER OF EARTH ON THE APPROPRIATE LAYER OF YOUR FOLDABLE (EX. CRUST NOTES, GO INSIDE EARTH'S CRUST) • IF YOU STILL HAVE TIME LEFT, USE THE COLORED PENCILS AT EACH STATION TO COLOR THE LAYER OF EARTH IN YOU FOLDABLE.
