Grade 3: Science: Toxic Noise

Instructional Design:
Kelly Raypold

Stage 1 - Desired Results

Established Goals:
The students will:
- recognize that there are ways of measuring the loudness of sounds and that sounds pose a danger to the ear
- construct and evaluate different kinds of soundproofing and sound-amplifying devices
- use technology to organize and display data in a problem-solving context
- use technology to support and present conclusions

ICT Outcomes:
Below is a pdf file identifying all of the ICT outcomes touched on throughout this project. Click on the file to download it to your computer.

Enduring Understandings:
Loud noises can be damaging to our ears. We need to have ear protection to ensure we maintain good hearing. Ear protection can be made from a variety of materials.
There are ways to amplify sounds that are difficult to hear. Devices can be made from a variety of animals.

Essential Questions:
How can we protect our ears from damaging loud sounds in our environment?
What materials will help to protect our ears?
How can we amplify sounds that are quiet?
What materials will help to amplify sounds?
How can we share this information with others?

Students will know and be able to:
- Measure various sounds and describe them as quiet or loud.
- Determine whether sounds are dangerous to the ears.
- Determine whether sounds are too quiet to be heard.
- Experiment with a variety of materials to create soundproofing and sound-amplifying devices.
- Describe materials that can be used for soundproofing or sound amplifying.
- Will construct different devices to soundproof and amplify sound.
- Display their information using a multimedia format (slideshow)  
- Experiment with using a digital camera and transferring image to slideshow

Stage 2 - Assessment Evidence

Performance Task(s)
As an audiologist (an expert in hearing and sound) you have been asked by the Parent Council of Vital Grandin School to prepare a presentation to educate others about what sounds students may come in contact with in their daily environment. The council would like you to create soundproofing and sound-amplifying devices that will assist the students in their daily environment. These items should also be described in your presentation.

Other Evidence (Quizzes, test, etc)
Rubric assessment of designs (soundproofing and sound-amplifying devices)
Observation and anecdotal records

Self Assessment
Journal reflection
Oral discussion, etc.

Stage 3 - Learning Plan

Teaching and Learning Activities
1.  Class discussion on what types of sounds are harmful to our ears and what types of sounds are too quiet for us to hear. Review previous knowledge on this topic and review the sound meter and which decibel levels fall into the various ranges of the safe hearing chart.  
2.  Students will brainstorm various sounds they hear at the school and predict where they would fall in the sound meter ranges.
3.  Students will move around the school in groups recording decibels of various sounds into a chart.
4.  Students will graph the results.

1.  Students will predict which materials they will need to create soundproofing and sound amplifying devices.  
2.  In groups of 2 or 3 the students will design on paper a sound amplifying device. They will label their diagram and list the material they will need to create the devices.
**Digital pictures will ba taken at various times throughout the process.

1.  Students will create their designs and test them.
2.  They will record their results in a lab book.
**Digital pictures will be taken at various times throughout the process.
Students will use digital pictures, words, clipart, graphs (teacher-created based on student info. collected on day one) to prepare a slide show presentation.  
Students will use a story board format to plan their presentation.  All writing will be edited prior to recording into presentation. Students will select digital images prior to working on their presentation in order to place pictures with appropriate writing.

Computer lab sessions:
Session1 & 2 Exploration of Presentation Theme: animals
Logon, Launch Presentation
Select a background (from assignment folder). Make 4 slides to begin:
     1.Title + name +add  clipping/picture from library
     2.Title next slide dog. Using clippings library. Write one sentence.
     3.Title next slide with favorite animal.         
      4.Use google to find picture and copy to slide
     5.Title next slide with favorite animal.        
      6.Use google to find picture and download picture to folder. Show how to insert picture from folder

Session 3
1. Select background. 2. Create title page. 3. Create 1 page at a time and add text only.

Session 4
1.Complete texts  2. Begin inserting pictures.

Session 5
1.Students create a graph from a teacher made table on sounds measured at Vital Grandin school. Students copy and paste graph into slide show. An explanation of the graph is written.

Session 6
1. Complete work. Demonstrate transitions and play options.

PS. Create a folder called Sounds in Assignment folder. Have pictures named and downloaded to Picture folder in Sound  folder.

Additional Teacher Resources
These are documents for teachers and/or students that were developed to support the project.  Documents will always be available in pdf format as well as in the original format created (e.g. MS Word, AppleWorks, Inspiration, etc)
