Major modern technologies are based on waves and their interactions with matter. When waves interact, they superimpose upon or interfere with each other resulting in changes to the amplitude. All types of waves have some features in common. Waves are a repeating pattern of motion that transfers energy from place to place without overall displacement of matter. Waves (including sound and seismic waves, waves on water, and light waves) have energy and transfer energy when they interact with matter. International Technology and Engineering Educators Association - Technology Structures can be designed to serve particular functions by taking into account properties of different materials, and how materials can be shaped and used. When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light.Īlignment agreement: Thanks for your feedback! The path that light travels can be traced as straight lines, except at surfaces between different transparent materials (e.g., air and water, air and glass) where the light path bends.Īlignment agreement: Thanks for your feedback! A wave model of light is useful for explaining brightness, color, and the frequency-dependent bending of light at a surface between media.Īlignment agreement: Thanks for your feedback! However, because light can travel through space, it cannot be a matter wave, like sound or water waves. This lesson focuses on the following Three Dimensional Learning aspects of NGSS:ĭevelop and use a model to describe phenomena.Īlignment agreement: Thanks for your feedback! Ask questions that can be investigated within the scope of the classroom, outdoor environment, and museums and other public facilities with available resources and, when appropriate, frame a hypothesis based on observations and scientific principles.Īlignment agreement: Thanks for your feedback! Construct an explanation that includes qualitative or quantitative relationships between variables that describe phenomena.Īlignment agreement: Thanks for your feedback! Explain the difference between additive and subtractive color.ĭevelop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.Ĭlick to view other curriculum aligned to this Performance Expectation.
