Stickleback Fish Structure Analysis

The video tutorial guides students through a virtual lab on stickleback fish evolution. It outlines success criteria, learning objectives, and methods for collecting and analyzing data. Students learn to identify pelvic structures in fish samples, score them, and discuss findings with peers. The tutorial emphasizes the importance of evidence-based conclusions and respectful group discussions.

What is one of the key criteria for success in the stickleback evolution lab?

• Completing the lab in under an hour

• Avoiding group discussions

• Staying on task and participating in discussions

• Using only online resources

What is the primary objective of analyzing the pelvic structures of stickleback fish?

• To identify differences between populations from two lakes

• To determine the age of the fish

• To find out the diet of the fish

• To measure the size of the fish

In the tutorial, what are the two views used to score the pelvic structures of stickleback fish?

• Lateral and ventral views

• Dorsal and lateral views

• Anterior and posterior views

• Ventral and dorsal views

What should students do if they score below 15 out of 20 in the tutorial?

• Proceed to the next experiment

• Ask for help from a partner

• Start the tutorial again

• Skip to the conclusion

During Experiment 1, what is the first step after clicking on the jar of stained fish?

• Click on the data table

• Click on the fish tank

• Click on the microscope

• Click on the strainer

What is the main focus of the discussion questions in Experiment 1?

• The color of the fish

• The size of the fish

• The pelvic structure phenotypes

• The age of the fish

What is the purpose of creating a bar graph in the data analysis section?

• To visualize the differences in pelvic structures

• To compare the size of the fish

• To track the growth rate of the fish

• To measure the weight of the fish

Which population of stickleback fish is being compared to marine stickleback fish?

• Only Bearpaw Lake population

• Only Frog Lake population

• Bearpaw Lake and Frog Lake populations

• Neither population

What is the final step in the lab after writing the initial response?

• Submit the response

• Discuss with a new partner

• Start a new experiment

• Revise the response based on feedback

What should students use to ensure they write their best response?

• The response checklist

• A thesaurus

• A dictionary

• A calculator
