===[|Designing Sound Systems] ===

media type="custom" key="22193700" media type="custom" key="22193706"

As you know, your child has been participating in a science and technology module on sound. At home, students are going to create their own instruments to present to the class. Because this project is due around the same time as the Steck science fair, students may choose to enter their sound system into the fair.

The first part of this module has provided an opportunity for children to do scientific inquiry as they investigate how objects produce sound. In the process, students have been · Asking the question, “How do things make sound?” · Investigating things that make sound. · Getting information from their investigations. · Using the information to construct an explanation of how things make sound. · Sharing their investigations and explanations.

As a reminder, the last part of the module will allow your child to participate in the process of technological design; children will use what they have learned about sound to design a simple system that will produce sound. This will be done as a homework project that will be presented in class January 18th. Students will be preforming in front of a green screen that will provide creative backgrounds. All presentations will be posted on our class wiki for parents and families to access. Please review the plan and rubric attached below with your child, which describes the expectations for the plan (due 12/19), poster (due 1/11), sound system (due 1/18), and presentation (1/18).

In the process, they will do these things **at home…** · Gather ideas about making something that would produce sound. · Choose one idea. · Plan how they would make it. · Build and test it. · Change it, if necessary. · Prepare to share what they did in a class sound show.
