1. INVESTIGATION 3 DATE: 1/7 LT: I CAN ANALYZE DATE TO PROVIDE EVIDENCE OF PAST PLATE MOTION. SPONGE: WHAT IS MORE DENSE, ROOM AIR OR HELIUM?

2. TO DO…

3. ENGAGEMENT HTTPS://WWW.YOUTUBE.COM/WATCH?V=11GZN31BCSA HOW COULD WE RECONSTRUCT THE DISH? IF A FEW SMALL PIECES WERE DESTROYED OR MISSING, HOW WOULD THAT AFFECT US BEING ABLE TO PUT IT TOGETHER? HOW IS THIS DISH SIMILAR TO THE EARTH?

4. EARTH’S PLATES EARTH’S CRUST IS DIVIDED INTO PLATES, SIMILAR TO THE PIECES OF THE DISH. PLATES INCLUDE LAND THAT WE SEE AND LAND UNDER THE OCEANS. WE CALL THAT OCEANIC AND CONTINTENTAL CRUST. HAVE THEY MOVED?

5. CONTINENTAL DRIFT IN THE EARLY 1900S, A GERMAN SCIENTIST NAMED ALFRED WEGENER BEGAN THINKING ABOUT THAT VERY QUESTION AFTER EXAMINING A MAP OF THE CONTINENTS. YOU ARE GOING TO LOOK AT THE CONTINENTS AS WEGENER DID AND SEE WHAT HE SAW.

6. CONTINENTAL DRIFT – NB 98 CLEAR YOUR DESK OF EVERYTHING BUT YOUR NOTEBOOK AND A PENCIL. TAKE ONE MINUTE TO SILENTLY MAKE A PREDICTION GET YOUR CARTON. CUT THE PIECES OUT AND TRY TO FIT THEM TOGETHER LIKE THE PIECES OF A PUZZLE. GLUE THEM ON THE BOTTOM OF NOTEBOOK 98.

8. CONTINENTAL DRIFT WHAT DID YOU NOTICE ABOUT THE CONTINENTS? WEGENER PREDICTED THAT THE LARGE LANDMASS CALLED PANGAEA SLOWLY BROKE APART INTO PIECES AND SLOWLY DRIFTED APART. HE CALLED THIS CONTINENTAL DRIFT.

10. INVESTIGATION 3 DATE: 1/8 LT: I CAN ANALYZE DATE TO PROVIDE EVIDENCE OF PAST PLATE MOTION. SPONGE: HAVE THE CONTINENTS ALWAYS BEEN WHERE THEY ARE TODAY?

11. TO DO…

12. CONTINENTAL DRIFT PUZZLE CLEAR YOUR DESK OF EVERYTHING! TODAY’S PUZZLE IS SIMILAR TO YESTERDAY, ONLY IT ADDS FOSSIL EVIDENCE. AS A GROUP, USE THE FOSSILS TO MATCH UP THE CONTINENTS. WHAT DO YOU NOTICE? HINT…LOOK AT PLANTS. ARE THEY IN WARM AREAS? HINT…LOOK AT REPTILES. CAN THEY SWIM? COUNT YOUR PIECES BEFORE YOU PUT THEM AWAY.

13. BIG IDEA! REPTILES CAN’T SWIM ACROSS OCEANS! FERNS WOULDN’T BE IN COLD ANTARCTICA! REPTILES COULDN’T BE IN COLD ANTARCTICA!

14. CONTINENTAL DRIFT VIDEO HTTPS://HUZZAZ.COM/COLLECTION/GEOSCIENCE- PROCESSES?HZV=316600 WE WILL BE CREATING A GRAPHIC ORGANIZER AFTER THE VIDEO WITH THE NEW INFORMATION WE LEARNED!

17. INVESTIGATION 3 DATE: 1/11 LT: I CAN ANALYZE DATE TO PROVIDE EVIDENCE OF PAST PLATE MOTION. SPONGE: WHAT IS MORE DENSE – THE OIL IN THE BOTTOM OF THE SALAD DRESSING OR THE VINEGAR ON TOP?

18. TO DO… AGENDA

19. REVIEW…. DENSITY – WHAT IS THE MOST DENSE ITEM SHOWN? LEAST DENSE ITEM SHOWN? LAYERS OF THE EARTH – WHICH IS MOST DENSE? LEAST DENSE? CONTINENTAL DRIFT / WEGENER / PANGAEA HTTPS://WWW.YOUTUBE.COM/WATCH?V=NBU8 09CYRAO HTTPS://WWW.YOUTUBE.COM/WATCH?V=NBU8 09CYRAO

20. COPY IN YOUR INDEX PANGAEA: SUPERCONTINENT THAT EXISTED LONG AGO CONTINENTAL DRIFT: WEGENER’S THEORY THAT THE CONTINENTS WERE ALL ONCE TOGETHER AND MOVED APART DENSITY: MORE DENSE ITEMS SINK, LESS DENSE ITEMS FLOAT!

21. PERFORMANCE ASSESSMENT – PLATE TECTONICS 1. WHICH LIQUID IS MORE DENSE, A OR B? 2. WHICH CORRECTLY LISTS THE ORDER OF THE LAYERS FROM THE SURFACE TO THE INSIDE? A. CRUST, MANTLE, INNER CORE, OUTER CORE B. MANTLE, CRUST, INNER CORE, OUTER CORE C. CRUST, MANTLE, OUTER CORE, INNER CORE D. INNER CORE, OUTER CORE, MANTLE, CRUST

22. 3. WHICH OF THE FOLLOWING STATEMENTS IS NOT EVIDENCE TO SUPPORT WEGENER’S THEORY OF CONTINENTAL DRIFT? A. FOSSILE OF PLANTS AND ANIMALS THAT COULD NOT HAVE CROSSED AN OCEAN ARE FOUND IN FARAWAY CONTINENTS. B. THE CONTINENTS LOOK AS IF THEY COULD FIT TOGETHER LIKE PIECES OF A PUZZLE. C. MOUNTAIN FORMATIONS IN FARAWAY CONTINENTS MATCH EACH OTHER. D. GLACIER REMAINS ARE FOUND ONLY IN COLD PLACES.

23. 4. ICE FLOATS ON WATER. WHAT IS MORE DENSE, ICE OR WATER 5. WHAT IS LEAST DENSE LAYER OF THE EARTH?
