Duration: 60 minutes

Class Size: 20 Students

Unit: Waves in Motion (Lesson 3 of 5)

---

Learning Objectives

By the end of this lesson, students will be able to:

• I can identify and explain the wave properties: amplitude, frequency, and energy.
• I can describe how changes in amplitude and frequency affect the energy and behavior of waves.
• I can conduct experiments to observe wave properties in action.
• I can summarize my observations using a graphic organizer and relate wave properties to real-world examples.

Standards Alignment

Next Generation Science Standards (NGSS) [aligned with Common Core Science Literacy]:

• MS-PS4-1: Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
• MS-PS4-2: Develop and use a model to describe that energy can be transferred through waves.

Common Core State Standards (CCSS) for Literacy in Science:

• CCSS.ELA-LITERACY.RST.6-8.3: Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
• CCSS.ELA-LITERACY.WHST.6-8.2: Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information clearly.
• CCSS.ELA-LITERACY.SL.6.1: Engage effectively in collaborative discussions with diverse partners on grade 6 topics, texts, and issues, building on others' ideas and expressing their own clearly.

---

Success Criteria

• Students can explain amplitude, frequency, and energy properties using age-appropriate language.
• Students accurately measure and record results during experiments.
• Students complete and fill a graphic organizer that clearly links wave properties to behavior and real-world examples.
• Students actively participate in group discussions, showing understanding through verbal explanations.

Materials Needed

• Slinkys or jump ropes (for wave demonstration)
• Water ripple tanks or trays of water to create waves
• Rubber bands of different sizes (to simulate waves)
• Stopwatches or timers
• Graphic organizer handouts (dyslexia-friendly fonts like OpenDyslexic)
• Notebooks or science journals
• Chart paper and markers
• Visual aids with simplified diagrams and color coding

Lesson Breakdown

1. Engage (10 minutes)

• Start with a question: “What happens to the energy of a wave when its frequency changes?”
• Show a short demonstration using a slinky: create waves by moving one end with different speeds and amplitudes.
• Ask students to observe and describe what they notice about the wave behavior.
• Use clear, dyslexia-friendly visuals projected or displayed, emphasizing key vocabulary: Amplitude, Frequency, Energy.

2. Explore (20 minutes)

• Experiment Stations: Divide students into small groups (4 groups of 5 pupils). Each group rotates every 5 minutes through stations:

  • Station 1: Using rubber bands stretched to different lengths to observe changes in amplitude.
  • Station 2: Creating waves in water trays and varying the frequency of wave generation.
  • Station 3: Using slinkys to measure wave speeds and relate frequency to energy.
  • Station 4: Real-world example discussion and application - matching wave concepts to examples like sound waves, light waves, and ocean waves.

• Provide a graphic organizer for students to fill at each station:

  • Column 1: Property (Amplitude/Frequency)
  • Column 2: What changed?
  • Column 3: What happened to the wave?
  • Column 4: How did energy change?

• Differentiation:

  • Provide step-by-step guided instructions and sentence starters for students who need extra support.
  • Allow use of audio-recorded instructions or peer partners for ELLs (English Language Learners).
  • Use tactile wave models for kinesthetic learners.

3. Explain (10 minutes)

• Groups share out one key finding from their experiments using sentence frames ("When we increased ____, we noticed that ____ because ____").
• Teacher models linking properties with energy transfer, reinforcing vocabulary and concepts with visuals.
• Summarize: Higher amplitude means more energy; higher frequency means waves pass more often transferring energy more quickly.

4. Elaborate (10 minutes)

• Students individually complete a simplified reading passage (designed for dyslexic learners with clear fonts and spacing) on how these wave properties affect real-world situations like music volume, light brightness, and earthquake intensity.
• Have students write or draw one real-life example in their graphic organizer and label which wave property it relates to.

5. Evaluate (10 minutes)

• Short "Quick Quiz" – 5 questions mixing multiple choice and short answer to assess understanding of amplitude, frequency, and energy relationships.
• Self-assessment: Students check off “I can…” statements they feel confident about and write one question if unsure.

Extension Activities (For Advanced Learners)

• Investigate how changing wave frequency affects pitch in sound waves with simple apps or instruments.
• Research waves in digital communication (WiFi, radios) and present how amplitude and frequency impact signals.
• Create a multimedia presentation or animated model showing wave energy transfer.

---

Differentiation Strategies

• Visual aids with color-coded wave properties to help visual learners
• Provide graphic organizer in digital and paper formats
• Use peer buddies and small group collaborations for social learning supports
• Allow alternative responses (drawing vs. writing)

---

Dyslexia-Friendly Reading Options

• Use OpenDyslexic or Comic Sans fonts printed in large size.
• High contrast between text and background (black on white or yellow)
• Short paragraphs with bullet points
• Use illustrations and captions to aid comprehension
• Provide audio version of passages if possible

---

Reflection for Teachers

• Observe which stations engaged students most and adjust timing accordingly.
• Use student verbal feedback and quiz data to plan differentiated review in Lesson 4.
• Consider incorporating technology next lesson to simulate waves digitally.

This lesson seamlessly blends hands-on inquiry, collaboration, and scientific literacy aligned with Common Core standards and NGSS, creating a rich experience where students see the invisible nature of waves come alive through direct interaction and reflection!
