What Biologists Do #3 | Crash Course Biology (2024) YouTube Video Lesson

Make What Biologists Do easier to teach with a no-prep YouTube video lesson focused on biology careers, field and lab science, research questions, science communication.

This lesson shows students that biology is not one job or one classroom subject. Students learn how biologists work in fields, labs, medicine, conservation, agriculture, technology, and public health while using observation, measurement, collaboration, and communication.

Use this video guide for Grades 8-12 biology, environmental science, NGSS review, science literacy, sub plans, or discussion-based classes. Use this lesson during a course launch, career exploration day, lab-skills unit, or advisory enrichment block. The questions help students connect classroom biology to real scientific work and to the kinds of questions biologists investigate outside school.

Use this lesson with the Crash Course Biology Playlist.

Guidance & Summary

What Biologists Do: Crash Course Biology #3 is a short educational YouTube lesson designed to help students build biology knowledge through clear explanations, examples, vocabulary, and evidence-based questions.

This lesson shows students that biology is not one job or one classroom subject. Students learn how biologists work in fields, labs, medicine, conservation, agriculture, technology, and public health while using observation, measurement, collaboration, and communication.

The teacher guide aligns the lesson to NGSS Science and Engineering Practices and science-career / real-world application support. The questions are built to keep students accountable during viewing while supporting science vocabulary, evidence, and concise written explanation.

Why Teachers Use This Video Lesson

This guide gives students a clear structure for watching the video with purpose. Instead of passively viewing a fast-paced science video, students track important terms, examples, cause-and-effect relationships, and key explanations.

The questions work well for teachers who want students to use specific video evidence while learning about biology careers, field and lab science, research questions, science communication, real-world applications.

Differentiation Options

The teacher guide includes a written-response path and a multiple-choice quiz path.

• Use the written worksheet when students are ready to explain vocabulary, evidence, systems, cause and effect, and science concepts in more detail. Use the 10-question multiple-choice quiz when students need fewer writing demands, a faster assessment, or a more accessible review option.
• Support options include reading questions aloud, offering small-group testing, allowing extended time, previewing vocabulary, or having students explain selected answers orally.
