ENGLISH: Have students create a biographical podcast of a character from a recent story or novel covered in class. HISTOY: BACKGOND Have students create a podcast incorporating research, factual information, and trivia about the day they were born. Project 2: Sounds of Outside ATH: se these ideas to modify the main projects: Have students record sounds that can be calculated, such as sounds in a series or pattern. SCIENCE: Have students record sounds that are caused by scientific reactions (friction, electricity, entropy, etc.). ENGLISH: Have students include sounds that match the themes or situations from a scene in recently read literature. HISTOY: Have students record sounds that are created by something old or historical or that were available in the period of history being studied. CICL SAPLE 3

The quality of your speaking voice is one of the biggest factors in a successful recording. You may have a very interesting autobiography, but no one will listen if they are not able to understand or do not want to listen to your voice. Once you feel comfortable reading your autobiography, begin recording with the audio recorder. ead your entire autobiography from beginning to end, focusing on proper pausing, intonation, and clarity.

Find three locations of varying noise levels. One that is very quiet, IC one that is moderate, and one that is very loud. Examples: Quiet: A calm forest. A quiet suburban neighborhood in the middle of the night. An empty hallway when everyone is in class. oderate: A busy shopping center. A noisy classroom. Loud: A factory. The sidewalk next to a busy street. Write down the location you chose for each sound level. Quiet: oderate: Loud: C recorder at each of the locations. Choose sounds of varying volume levels at each of the locations. For example, the sound of leaves gently rustling in a breeze will be quiet, a dog barking is moderate, and the siren of a fire truck will be loud.

Select three unique sounds you would like to capture with your audio SA Audio ecorder Portable and Headphones Speakers & O At each location, close your eyes and listen for a unique or interesting sound, such as a bird chirping, a dog barking, or water running through a creek bed. 5.

Place the audio recorder into its sound test mode. (If you are using a microphone on a computer, you may skip this step.) 2. Simulate recording the sound. You want the sound test to be as close to an actual recording as possible. 3. Watch the sound meters on the recording device. The meters should average around -6 decibels and never above 0 decibels. If they do, the sounds will be distorted. 4. If your sound meters are too low or too high, you will need to adjust your recording. To adjust your recording, try changing the gain on the audio recorder, or place the recorder closer or farther away from the sound source. IC Loud Location: Sound 1: Sound 2: Sound 3: 6. Familiarize yourself with your audio C recorder. The basic features used in this exercise will be the record, stop, and play features. Be sure to have headphones connected to the recorder. EN 8. Listen to the sounds through the headphones. The way the sounds are heard through the headphones is the way they will sound in the finished recording. If you cannot hear the sound, the recorder cannot record it. 9. Once the sound levels are accurate, record oderate Location: Sound 1: Sound 2: Sound 3: the sounds of your choice, and then stop recording. 7

Continue recording sounds until all nine of your sounds have been acquired. 12. Play back the recording for your class and see if they are able to identify each sound. 3. What is gain? Podcast eview: 1. Was your class able to identify the sounds? Why or Why not? Which ones were most difficult to identify? POJ 2: SONDS OF OTSIDE 4. What techniques did you find helpful in acquiring quality recordings? CICL SAPLE 8

8 CHALLENGE ONE: SOETHING TO BE KNOWN BY Create a personalized greeting and sign-off line that you will use in all future podcasts. The greeting is how you will start all of your radio shows and/or podcasts and the way in which listeners will be able to recognize you. For example, This is crazy Jay signing in to say hello and to bring you more fun times. Personalize your greeting to represent you. Your sign-off line is something you will say at the end of your shows and is a way to say good-bye to your listeners. For example, Thanks for listening, it's been fun. Be careful out there, it's a big world. Create a recording of each and re-record them until you are satisfied with how they sound. Listen to several different radio shows for ideas if necessary. Hint... Create greeting and sign off lines that represent your personality. This will make them sound more natural when you speak them. Think About How do your signature lines represent you? How did you personalize them? 2. How do reoccurring signature lines help others identify with your work? 3. What are other reoccurring things could be added to help others recognize your program? Journal Entry: use additional paper if necessary CICL CHALLENGES CHALLENGE TWO: SONDS OF A THEE Choose (or have assigned to you) a theme that all of your sounds will match. For example: all the sounds need to be created by friction, electricity, nature, echo, or chemical reactions. se your audio recorder to record a quiet, moderate, and loud sound of each in a variety of locations. ecord which sounds were the easiest to record and which were the most difficult. Also, note what obstacles you had to overcome to acquire each. Hint... Adjust your audio recorder by using the gain (or similar features) to accommodate for the sound levels around you. Think About Which sound did you find the most difficult to record? Which one was the easiest? Why? 2. What difficulties did you have to overcome to record sounds in a loud environment? What techniques did you use? 3. Were there sound issues that you couldn t overcome? Describe them. Journal Entry: use additional paper if necessary SAPLE 9
