This Grade 9–12 worksheet introduces key ideas related to drug abuse, brain function, and addiction through 10 multiple-choice questions. Students identify neuron structures such as dendrites, the cell body, and axons; recognize neurons as the brain’s nerve cells; connect the reward system with its associated neurotransmitter; and review the roles of glucose and the nervous system’s “command central.” The worksheet also checks students’ understanding of drug-related vocabulary, including cocaine, alcohol, and addiction, and asks them to identify the full name of a PET scanner. These definition-based questions help students distinguish closely related terms and apply health-science vocabulary in context. It is a free printable worksheet with a complete answer key for classroom practice, review, or formative assessment.

FAQs

What does the Drug Abuse worksheet cover?

This worksheet uses 10 multiple-choice questions to assess vocabulary about neuron structures and functions, the brain’s reward system, drug effects, PET scanning, glucose, and addiction. Students build recognition skills by distinguishing terms such as dendrites, cell body, neurons, cocaine, alcohol, and addiction from plausible distractors.

How can I use this worksheet to teach brain and addiction concepts?

Introduce the worksheet by reviewing a simple neuron diagram and defining dendrites, the cell body, and axons before students begin the multiple-choice items. After completion, have students explain why each selected term fits its definition, then connect the reward-system, drug, and addiction questions to a broader discussion of how substance use can affect the brain and behavior.

What mistakes should I watch for when students complete this worksheet?

Students may confuse dendrites, the cell body, and axons because all three are neuron-related terms, or select synapses and synaptic clefts when the question asks for the brain’s nerve cells, neurons. They may also mix up drug categories such as cocaine and alcohol, confuse addiction with withdrawal, or choose a distractor instead of the full term Positron Emission Tomography for PET.

How do I assign and grade this Drug Abuse worksheet?

The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 10 multiple-choice questions. For printable submissions, you can grade student work by scanning it with the Wayground for Teachers app.

How can I differentiate this worksheet for my students?

Because this worksheet presents 10 definition-based multiple-choice questions, you can adjust font spacing and font size to make the question stems and answer choices easier to read, or enable a dyslexia-friendly font. These options, along with translation into another language, are available under the worksheet’s Advanced Settings.
