Medium Grade 4 practice linking wave properties to everyday experiences. Students complete nine fill-ins on whispers, mouse squeaks, flashlights, and red versus blue light, then match changes in amplitude or wavelength to changes in loudness, brightness, color, and pitch under NGSS 4-PS4. Students examine echoes, sound insulation, and light absorption in cars, classrooms, and homes through fill-in problems and matching exercises for Grade 4 learners.
Style:
Waves: Light and Sound
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A whisper is quieter than a shout because the whisper's sound wave has a smaller amplitude.
2. A tiny mouse squeak has a higher pitch than a big lion roar.
3. A bright flashlight sends out light waves with a larger amplitude than a dim flashlight.
4. Red light has a longer wavelength than blue light, so red has a lower frequency.
5. When you shake a jump rope slowly, you make longer wavelengths than when you shake it fast.
6. A sound wave with the same amplitude but a shorter wavelength will sound higher in pitch.
7. Drumming your fingers gently on the desk makes a sound with a small amplitude and a soft volume.
8. Light waves and sound waves both have wavelength, amplitude, and frequency.
9. A tuning fork that is hit harder vibrates with a bigger amplitude and makes a louder sound.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Big amplitude in a sound wave
→ Loud sound
Loud sound
Big amplitude in a light wave
→ Bright light
Bright light
Short wavelength of light
→ Bluer color
Bluer color
Short wavelength of sound
→ Higher pitch
Higher pitch
