Students will discuss vibrations, frequency, amplitude, and wavelength. They will observe instruments, hypothesize how sound waves are created, and experiment with creating sound.
Students observe waves propagate through deep water in videos and animations showing that waves transport energy, not matter. Students can make observations to describe wave motion through the water. This is a great engaging activity to use to introduce waves.
Sound is energy that travels as a result of vibration. It can be characterized by frequency, loudness, and pitch, and it is measured in decibels.
The classroom resource provides a video that will explain sound energy, how it moves, and how it is measured. This resource can provide background information for students before they create their own models and conduct their own experiments. There is also a short test that can be used to assess students' understanding.
Students observe, compare, and describe waves, using videos and images of actual waves as well as model diagrams. This interactive lesson engages students in noticing the shape of (transverse) waves and learning how to describe and measure the amplitude and wavelength of waves.
A wave is energy in motion or energy moving from point to point. To describe the traits of a wave, there are a few terms you need to know.
Students will choose a term in the activity to display its description in the diagram.
Students will play the role of the audio engineer who monitors and adjusts the audio levels for a production. This animated interactive job exploration experience connects schoolwork with real work and familiarizes students with some of the skills involved in audio engineering. They will also understand the parts of waves and that the intensity (loudness or softness) of sound is determined by the amplitude of the sound wave.
In this activity, students learn about the parts of a wave, wave height, and wavelength and then draw and label a wave.
In this activity, students learn about waves by comparing and contrasting photographs and watching a hands-on demonstration. Students will gather around a pan of water. Demonstrate how waves of different sizes are formed by tilting the pan in different directions and disturbing the water. Put a cork in the pan to represent a boat on the ocean. Ask students to describe how the cork moves as the waves change in size.
This lesson introduces students to the electromagnetic spectrum (focusing on visible light) and the wave nature of light. Students will be introduced to the idea that all light travels as waves and that wavelength defines the various regions of the electromagnetic spectrum. There are three Science NetLinks lessons in this series on light.
This lesson focuses on the idea that we can see objects because they either emit or reflect light. This lesson will lead to a discussion about the way light is reflected, absorbed, and scattered to allow certain wavelengths to reach the eye, leading to a perception of different colors. There are three Science NetLinks lessons in this series on light.
