During our “Which Light Bulb?” unit, you have learned about the different technologies available for lighting our homes, including incandescent bulbs, Compact Fluorescent bulbs (CFL), and LED lights. You must argue your case for which bulb you would choose to buy for your home.
As we’ve talked about in our unit so far, you are pretending that you have inherited a beautiful new house that needs new light bulbs to be purchased for it.
Using the websites below plus the information given in class, you will present a convincing argument for which light bulbs to choose in the form of a Keynote presentation. See the “Evaluation” section for the rubric I will use to assess your work, and the Credits section to see the standards to which this work relates.
Your presentation must:
- be supported by and include at least 3 pieces of economic data from the websites listed
- be supported by and include at least 3 pieces of environmental data from the websites listed
- be at least 7 slides long, including an introduction slide that contains your name, the name of your base class teacher, and the name of the project.
- use at least 5 images, which are correctly cited in APA format (see Citation Machine to see how to correctly cite images you get from the Web). If you use images that you create yourself (by taking a digital picture, for example), simply include your name for the photography credit – you do not need to cite your own photo with Citation Machine.
First, visit at least 3 of the following sites (one per category)
Compact Fluorescent Lights (CFL)
- compare environmental data for each type of bulb (ex: what is the environmental impact of each bulb? how much waste is produced by making or using each bulb?)
- compare price and other economic data for each type of bulb (ex: how does each type of bulb compare in terms of price?)
- list the pros and cons of each bulb (what do you like and dislike about each bulb?)
- sum up your conclusion in your final slide, using an easy-to-read statement about which bulb you finally decided upon.
I will evaluate this assignment based on the following rubric:
|Presentation uses economic data that supports your conclusion.||Includes 0 or 1 pieces of economic data that support your conclusion||Includes 2 pieces of economic data that support your conclusion||Includes at least 3 pieces of economic data that support your conclusion||Includes more than 3 pieces of economic data that support your conclusion|
|Presentation uses environmental data that supports your conclusion.||Includes 0 or 1 pieces of environmental data that support your conclusion||Includes 2 pieces of environmental data that support your conclusion||Includes at least 3 pieces of environmental data that support your conclusion||Includes more than 3 pieces of environmental data that support your conclusion|
|Use of images and formatting||Your presentation contains no images, or only one image. The formatting of your presentation is inconsistent, and the organization makes it hard to follow your ideas.||Your presentation uses 2 or 3 images. Your presentation’s format is mostly good and generally organized.||Your presentation includes 4 or 5 images. Your presentation’s format is well organized, showing clear ideas.||Your presentation includes at least 5 images. Your presentation’s format follows good design principles and is well organized, with each slide presenting a single clear idea.|
|Final decision on which light bulb to use||Your final decision is not stated or hard to understand. Data used may not support your conclusion.||Your final decision is stated, but may be somewhat confusing. The final decision may not be fully supported by your data.||Your final decision is clearly stated, and is mostly consistent with the data used in your presentation.||Your final decision is clearly stated, easy to understand, and is consistent with the data used in your presentation.|
Now that you have come to your conclusion, spread the word! Talk to your parents about which light bulbs you think would be right for your family. Look around your school at which types of light bulbs you see in use. Read more about the issues and watch for even more new, emerging technologies that technologists develop for producing environmentally friendly light.
This lesson was created as an new add-on activity for the “Which Light Bulb?” unit I teach at Honey Creek Community School. This curriculum was originally developed as part of the Envirotech program, directed by Mary Annette Rose from Ball State University. You can read more about my participation in Envirotech.
Standards referenced in this lesson:
3-5-2.CC.3. use a variety of media and formats to create and edit products (e.g., presentations, newsletters, bro- chures, web pages) to communicate information and ideas to various audiences
3-5.RI.2. use digital tools to find, organize, analyze, synthesize, and evaluate information
3-5.CT.3. use digital resources to identify and investigate a state, national, or global issue (e.g., global warming, econ- omy, environment)
Standard 5: Students will develop an understanding of the effects of technology on the environment.
Standard 6: Students will develop an understanding of the role of society in the development and use of technology.
