This comprehensive reading passage on waves is specifically designed for Grade 4 students and aligns with NGSS standard 4-PS4-1. Students explore the fundamental concept that waves are disturbances that transfer energy from one place to another without moving matter. Using water waves as the primary example, the passage helps students understand the difference between wave motion and water motion. The resource includes audio-integrated reading support, making content accessible to all learners. Students discover how waves carry energy through various materials and why understanding waves matters in everyday life. The passage is accompanied by multiple activities including comprehension questions, writing prompts, and graphic organizers that reinforce key vocabulary such as wave, energy, disturbance, and motion. Spanish translations are provided for both the standard and simplified versions, supporting English language learners. This foundational understanding of wave behavior prepares students for deeper exploration of light and sound waves in subsequent lessons.

Waves are disturbances that move energy from one place to another. A wave is not made of matter moving from place to place. Instead, it is energy traveling through matter.
Water waves are a good example. When you drop a stone into a pond, you see waves move outward in circles. The water itself does not travel across the pond. If you watch a leaf floating on the water, you will see it bob up and down as the wave passes. The leaf moves up and down, but it stays in about the same spot. This shows that the water moves up and down while the wave moves forward.
Waves carry energy, not matter. The energy from the stone hitting the water travels outward through the water. This is called wave motion. The water particles move up and down or back and forth, but they do not move along with the wave.
Understanding waves helps us explain many things we observe. Ocean waves carry energy from wind across great distances. Sound travels as waves through air. Light reaches Earth as waves from the Sun. All these waves have one thing in common: they move energy from one location to another without moving the material itself.
What do waves move from place to place?
EnergyWaterMatterStones
How does a floating leaf move?
It travels across the pondIt moves up and downIt sinks to the bottomIt moves sideways only
What creates waves in a pond?
A leaf floatingWater moving forwardA stone hitting the waterThe wind stopping
Why doesn't water travel across the pond?
Water is too heavy to moveOnly energy moves, not matterThe pond is too smallWaves block the water
How do water particles move in waves?
They travel with the waveThey stay completely stillThey move up and downThey disappear and reappear
What do ocean waves and sound have?
They both need waterThey both carry energyThey both move matterThey both come from stones
Waves carry matter from place to place.
