Edited by: Erin Howard You should begin by explaining what grade, subject, and unit you are covering.

LESSON PLAN- Science 20- Unit D: ECOSYSTEMS Introduction

Terraforming means making other planets more like Earth, so that human beings can live there. Mars is presently under consideration for terraforming. This topic examines some of the economic, social, and ethical issues surrounding the technological challenge of turning the ‘Red Planet’ into another blue-green planet like Earth. Students will consider on what basis humans attribute value to things – both living and non-living. Terraforming offers possibilities for thinking about the environment from a rather different angle. Wow! What an interesting topic!! ** Background information: What is the terraforming debate? ** Scientists are debating terraforming as they plan interplanetary expeditions. NASA plans to land the first human on Mars by 2010. In the meantime it is researching the future possibilities of Mars as a ‘new frontier’, a new home for life forms at present able to exist only on Earth.

Mars at present is cold, (around –60 Celsius), almost airless and probably lifeless. Terraforming Mars would mean artificial melting of the polar ice-caps and the permafrost to produce liquid water and gaseous carbon dioxide, thereby increasing the surface temperature; and artificial production of gases to raise temperature and pressure and ultimately to provide protection from UV radiation for any newly introduced life forms.

There are already a number of ideas for how this massive undertaking could be begun including positioning solar mirrors in space and detonating nuclear devices underground. This would be a huge engineering and technological challenge, to which some scientists, technicians and engineers are understandably drawn.  Present this background information to the students through a powerpoint/smartboard presentation. Have them brainstorm the possible implications of terraforming Mars on society today. They could think/pair/share and come up with possible implications (positive and negative).

General Outcome (Science 20 Unit D)
 - Students will analyze ecosystems and ecological succession in the local area and describe the relationships and interactions among subsystems and components.

Specific Outcomes
Students will: 20–D1.2k describe the key stages of primary succession in a specific ecosystem and the nature of its climax community 20–D1.5k describe the effects of introducing a new species into, or largely removing an established species from, an environment 20–D1.1sts describe how society provides direction for scientific and technological development (SEC4) [ICT F2–4.4] 20–D1.1s formulate questions about observed relationships and plan investigations of questions, ideas, problems and issues By the end of the topic, we hope that most students will: · know and be able to explain the meaning of the term ‘terraforming’ · understand that there are ethical issues at the heart of the terraforming debate, and explain in detail differing viewpoints · state their own opinions about terraforming, justifying them in reasoned way

Key questions
 
 * What is terraforming? Can it be done? Should it be done?

Learning objectives
 1. To appreciate the uniqueness and beauty of Mars through a study of images 2. To become familiar with the term ‘terraforming’ and to understand the intentions of the Mars Exploration Program 3. To identify key beliefs behind differing points of view 4. To formulate reasoned opinions and viewpoints, linked to personal beliefs 5. To reflect upon human motivation in the area of terraforming

Using the Internet and/or other resources, determine answers to the following questions: <span style="font-size: 120%; font-family: Tahoma,Geneva,sans-serif;">After completing your research, perform a risk-benefit analysis to determine if terraforming Mars is worth the investment of time, money, and other resources. Use the results of your risk-benefit analysis to decide if terraforming Mars is a project you would support.
 * Student Directions**
 * 1.** What are some of the major obstacles to the terraforming of Mars?
 * 2.** What would be some of the particular challenges these first species would have to overcome in terms of abiotic conditions on Mars?
 * 3.** Are there some ethical, societal, or scientific concerns with the idea of terraforming? If so, what are they?

<span style="color: rgb(128, 0, 128);">Review with students some tips to effective internet research 1. Define your term and narrow it 2. pick a search engine which may be targeted towards science without many sponsored responses. 3. use symbols such as & or to limit number of searches 4. ensure that your sources are legitimate and cannot be edited (ex. Wikipedia) 5. Use non-internet sources to back up your research.

<span style="font-size: 10pt; color: rgb(0, 0, 0); font-family: Verdana,Geneva,sans-serif;">Asessment
<span style="font-size: 10pt; color: rgb(0, 0, 0); font-family: Verdana,Geneva,sans-serif;"> The student will prepare a 5 minute presentation describing their position on terraforming mars. Included in their presentation should be a visual representation of their risk-benefit analysis (Poster, Picture, Powerpoint, etc) for reference. The student will hand in their risk-benefit analysis, along with the three answers to the questions posed above.<span style="font-size: 120%; font-family: Tahoma,Geneva,sans-serif;">

<span style="color: rgb(128, 0, 128);">Sean, This is a good lesson plan and a very interesting topic. Your extra sources at the end of the lesson are extensive and are a great addition to the lesson. The only suggestion I would have for you is to incorporate how to effectively research sources on the internet with your students. Chances are that they have learned this in other classes but may need a quick reminder to help them along. Well done!! <span style="color: rgb(128, 0, 128);">Erin H. <span style="font-size: 10pt; color: rgb(0, 0, 0); font-family: Verdana,Geneva,sans-serif;">
