1. Go to Expedition GC.
2. Open the PLATE TECTONICS MYSTERY assignment.
3. Click the link.
4. Log in with Google.

Lesson 1: The solve

Step 1: The phenomenon

1. Watch video clip together
2. Complete reflection questions
3. Click submit!

Step 2: earth’s layers

The earth is divided into four core parts:

● The inner core – a hot, dense ball that is mostly made of iron.

● The outer core – a liquid layer made primarily of iron and nickel.

● The mantle – made up of rock that behaves like a really thick liquid at times. The mantle is considered “plastic” because it has properties of both a liquid and a solid.

● The crust – our home! The crust is a thin outer shell that surrounds the mantle of the earth. The crust is divided into several tectonic plates. These hard and rigid plates are constantly moving, very slowly, over the mantle.

The earth's crust is divided into 15–20 tectonic plates that are constantly moving. Today's mystery takes place on and around the South American plate.

Step 3: plate motion

Let’s explore how the plates move!

1. Open the game and follow the directions on your screen.
2. While you play the game, answer the 4 questions.
3. Click SUBMIT when you finish!

Step 4: deepen your research

Now that you have explored some clues behind the mysterious whale fossils, view a video that shows the plate movement of the Nazca Plate and the South American Plate—the two plates right next to Cerro Ballena.

​

Your directions:

1. Watch the video!
2. Answer the 2 questions!
3. Click submit!

Step 5: Construct an explanation

Reflecting on what you saw in the videos and your experiences playing the plate tectonic game, brainstorm your possible explanation for the phenomenon you observed at the beginning of the lesson.

​

Answer this question and click submit when you are finished:

How did whale fossils that were originally located on the ocean coast end up in a desert hill?

Include as many of the terms as possible below to support your explanation.

• Crust: The outermost layer of the earth.
• Tectonic plates: The crust is divided into several hard and rigid plates that move slowly over the mantle.
• Fossil: The remains or traces of plants and animals that lived long ago.

​

Step 6: Quiz

1. Take the quiz!�
2. Read silently when you finish.

Lesson 1: solve (animation)

Step 1: Mystery

• We will watch the mystery once together!

Lesson 1: solve (animation)

Your tasks:

1. Watch the video again on your own
2. Complete the vocabulary activity
3. Complete the episode questions
4. Complete the quiz

Lesson 2: The Lab

Directions:

Today you're going to play the role of archaeologist and use data to show relationships between fossils on different continents. To do this, you’re going to make a “before” and “after” map of what the world looked like before and after Pangaea split, thus demonstrating the theory of plate tectonics.

Your Make task today is to:

1. Use fossil evidence to design a map of Pangaea before it split.

2. Identify the positions of the plates after Pangaea split.

3. Document the movement of the plates from their original positions to their current positions.

Lesson 2: The Lab

Step 1: Presentation

Lesson 2: The Lab -Step 3: pangaea data

1. Take some time to review the images on the bottom of your screen.
2. Answer questions 1-4 and click submit.

Lesson 2: The Lab -Step 4: planning organizer

​

1. Answer question #1.
2. Drag and rotate the continent pieces to model how they would have fit together in Pangaea, the supercontinent.
3. Click save.
4. Answer question #3.
