MS-PS1-3 Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.OR: A similar, more in-depth lesson plan "String Instruments and Pitch" can be found at Īssessment: Each group presents their instrument, explains the design, and plays the instrument for the class. Have the students attempt to play songs with their instruments.Tell the students that they will need to have a range of pitches with their new instruments. Again, in groups, have the students make new instruments with additional materials provided, such as aluminum pans, strings, or alternatively, have students bring their own materials to create new instruments.Online tuning forks and information can be found at: Īssessment: The students should have an understanding of why the pitch changed. Tuning forks can be used during the explanation. Introduce and define the terms frequency and pitch (see Content Knowledge).Students should report their findings of what affected the pitch to the entire class.Monitor the students to be sure they are recording information properly. Have the students observe and record what affects the pitch using either their original instruments or by making modifications to their original instruments.Īssessment: Make sure students are handling the supplies properly and following proper procedures.Note: Safety goggles should be worn since rubber bands are used during experimentation. Working in groups, have the students make instruments using the materials provided.Tell the students that they will be making musical instruments to investigate high and low notes (pitches).
The assessment is informal at this time and can be used to understand misconceptions that the students may have. Have the students make observations and discuss their thoughts on sound properties, such as low notes and high notes.Īssessment: Monitor the students' understanding of pitch and frequency, not necessarily using these terms.Begin by tapping or blowing on glass bottles that are filled with different amounts of water. During this phase, begin a discussion of sound and instruments.Other materials for creating instruments.Glass bottles filled with various amounts of water.Alternatively, you can have students bring in empty tissue boxes for making the instruments.Students will be able to make modifications to an instrument to change the pitch.Students will be able to explain frequency and pitch.What should the students be able to do as a result of this lesson? Students will understand factors that affect the pitch.Students will understand frequency and pitch, which are properties of sound.
What should students know as a result of this lesson? Students will design musical instruments from provided materials to understand the following properties of sound: frequency and pitch Printer Friendly Version Plink Plank PlunkĪuthor: Joy Vocke, Carolyn Kepler, Debra Boles, Yolanda Wiley, AGPA Staff
