 * Science Talk! **

__Lesson Tittle: __ How Sound Travels Through A String!

 __Objectives: __ - Students will participate in an inquiry investigation to develop hypothesis - Students will research the topic and arrive to a conclusion

__Motivation: __ Ask: Have you ever created a telephone using string and cups or cans? Today we are going to pair up with our elbow partner and assemble a telephone using those materials! (This will give the students a baseline in order to make assumptions during the class science talk).

__Instructional Sequence: __ 1. Ask motivation discussion question. 2. Pre-assessment task: **take out a piece of blank paper and fold it in half hamburger style. On the left side draw or write how you think sound travel through a string.** 3. Divide in pairs and complete inquiry investigation. 4. After the investigation three pairs at a time will sit with me and I will **record our science talk using Evernote**. Science talk question: //How does a homemade telephone work?// If you are not with me complete the following: Investigation Record Sheet - record observations and make predictions, you may draw pictures. 5. After each group participated in a science talk regroup as a class. Have the students click on the links below.

<span style="font-family: 'Times New Roman',serif;">6. After reading about why a homemade telephone works go back to your initial drawings "How Sound Travels Through a String" and use your newly learned knowledge to redraw a picture on the right side. In your drawing include new vocabulary such as vibrations and sound wave. <span style="font-family: 'Times New Roman',serif;"> 7. Discuss the drawings and create class conclusion to record in the Investigation Record Sheet. <span style="font-family: 'Times New Roman',serif;"> __<span style="font-family: 'Times New Roman',serif;"> Extension Activities/Homework Options: __ <span style="font-family: 'Times New Roman',serif;">Make the telephone using a variety of mediums; i.e. different strings, cans, plastic cup, styrofoam cup, etc. Which combination of materials worked best? Why? <span style="font-family: 'Times New Roman',serif;"> [|How does sound travel? Evernote Recording]
