Noodles a Roar, Stop that Snore!Objective : Students will understand the effects of acoustics, which includes how sound is measured (decibels) and how sound travels. After reading Two Problems for Sophia, by Jim Averbeck and Yasmeen Ismail, students will create and design a device that decreases the volume of noise heard on a speaker.Grade Level(s): Kindergarten – Second GradeGroup/Team Size: 3 per teamTime Required: 45 -60 minutesEducational Standards:From the North Carolina Essential Science Standards: (http://www.ncpublicschools.org/docs/acre/standards/new-standards/science/k-2.pdf)Students develop simple skills of observation, measurement and number sense as they actively participate in simple investigations. During investigations, students must have opportunity to use tools such as magnifiers, thermometers, rulers, or balances to gather data and extend their senses. They must have ample time to talk about their observations and compare their observations with those of others. They should be encouraged to employ oral language, drawings and models to communicate results and explanations of investigations and experiment2.P.1 Understand the relationship between sound and vibrating objects.From the Common Core Math Standards: (http://www.corestandards.org/Math/Content/2/MD/)NC.K.MD.1: Describe measurable attributes of objects; and describe several different measurable attributes of a single object.NC.K.MD.2: Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the differenceNC.1.MD.4: Organize, represent, and interpret data with up to three categories.1.MD.D.10: Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories.NC.2.MD.10: Organize, represent, and interpret data with up to four categoriesFrom STEM Connected Through Engineering (K-2):EG K-2 H 1: Infer that engineering has a way of thinking and solving problems that includes: systems thinking; communication; collaboration; optimism; creativity and ethical considerationsEG K-2 D 1: Use the engineering design process of ASK-IMAGINE-PLAN-CREATE-IMPROVEEG K-2 P 2: Use critical thinking to suggest solutions to problemsSTEM Learning Objectives:To represent and interpret data using a bar graph.To analyze the relationship between sound and objects that vibrate as a result of sound produced.To utilize the engineering design process.Materials: Each group of students will need at least the following materials.2 ft of Ribbon1 Roll of Duct tape1 Fabric Scrap1Cardboard Square 6” x 6” Square1 Styrofoam Cup1 BalloonPlay-dough
