Exploring Earth's Crust Features

The video tutorial covers the Earth's crust, distinguishing between continental and oceanic types. It introduces Activity 2, where students explore crust features through a hands-on model-building exercise. The activity involves using materials like modeling compound and markers to create a 3D model, highlighting features such as mid-ocean ridges and trenches. Students learn to label these features on worksheets and paint their models to distinguish between land and ocean. The session concludes with a museum walk to observe different models.

What is the main difference between continental crust and oceanic crust?

• Oceanic crust is thicker and contains continents, while continental crust is thinner and underlies the ocean.

• Both continental and oceanic crusts are the same thickness.

• Continental crust is thinner and underlies the ocean, while oceanic crust is thicker and contains continents.

• Continental crust is thicker and contains continents, while oceanic crust is thinner and underlies the ocean.

Which of the following is NOT a feature found on the ocean floor?

• Island

• Mid-ocean ridge

• Trench

• Desert

What material is used in Activity 2 to help students explore the Earth's crust?

• Clay

• Play-Doh

• Model Magic

• Plasticine

How is the Earth's crust similar to an egg shell?

• Both are the same thickness throughout.

• Both cover the entire surface of their respective bodies.

• Both are made of the same material.

• Both are used in cooking.

What is a mid-ocean ridge?

• A type of oceanic trench

• A flat plain on the ocean floor

• A mountain range on the ocean floor

• A deep valley in the ocean

Which feature is described as a valley in the ocean?

• Mid-ocean ridge

• Trench

• Island

• Continental shelf

What is the purpose of using a blue washable marker in the model activity?

• To label the continents

• To draw the mid-ocean ridge

• To mark the water line

• To color the ocean floor

Why should the island be painted green in the model?

• Because it is part of the ocean floor

• Because it is a volcanic island

• Because it is above the water line

• Because it represents a forest

What should students do after completing their models?

• Throw them away

• Start a new model

• Take them home

• Leave them to dry overnight

What is the educational purpose of the museum walk?

• To paint the models

• To start a new activity

• To clean up the classroom

• To compare different models
