Understanding Rock Age and CER

The video tutorial guides students through a project on determining the age of the Earth's crust using the CER (Claim, Evidence, Reasoning) method. It explains how to make claims, support them with evidence, and provide reasoning. Students are tasked with analyzing rock samples, creating graphs, and using background knowledge to understand plate boundaries. The tutorial emphasizes the importance of organizing data and connecting evidence to scientific principles.

What does CER stand for in the context of this project?

• Conclusion, Explanation, Result

• Conclusion, Evidence, Reasoning

• Claim, Explanation, Result

• Claim, Evidence, Reasoning

In the geologist scenario, what is the main task given to the students?

• To classify different types of rocks

• To determine the age of rocks

• To find new rock samples

• To map the locations of rock samples

What resource is suggested for help in determining the age of rocks?

• Unit 1.1

• Unit 2.1

• Unit 4.1

• Unit 3.1

Why is it important to create graphs from the rock data?

• To easily visualize and analyze the data

• To fulfill a project requirement

• To compare with other students' data

• To make the data look more colorful

What is the main question the students need to answer using their data?

• Which rock is the heaviest?

• What is the oldest type of crust?

• Which location has the most rocks?

• What is the most common rock type?

What should students use to support their claim about the age of the crust?

• Personal opinions

• Data tables and graphs

• Teacher's notes

• Classroom discussions

What is a key factor in explaining the age of rocks?

• The size of the rocks

• The location and proximity to plate boundaries

• The color of the rocks

• The type of minerals in the rocks

What should students do after answering all the questions about rock locations?

• Write a report

• Start a new project

• Create a CER

• Submit their project

How should students connect their evidence to their claim?

• By using scientific principles

• By guessing

• By asking a friend

• By using unrelated data

What is the final step in creating the CER?

• Explaining why the evidence supports the claim

• Writing a summary

• Drawing a diagram

• Creating a presentation
