This resource turns radio and tv signals into a complete, ready to use review for Grade 6-8 physics, covering the same idea from three different angles.

Among the ninety questions, students will see prompts such as "Which modulation technique varies the amplitude of the carrier signal?", "What is the primary function of an antenna in radio transmission?", and "Which signal type is less susceptible to noise, AM or FM?"

What's Inside?

• 30 Multiple Choice questions as a separate print ready PDF worksheet
• 30 True or False questions as a separate print ready PDF worksheet
• 30 Short Answer questions as a separate print ready PDF worksheet
• Includes Answer Key with Explanations for all 90 questions
• 6 print ready PDF files, 26 pages in total

Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.

Ways to Use This Resource

• No prep cover lesson for a substitute teacher
• First look diagnostic to plan your unit
• Bell ringers and warm ups during the unit
