GEOGRAPHY, GRADE 7 BOYS, THREE 43 MINUTE CLASS PERIODS.
Objectives for learning.
By the end of the week students will understand main issues and themes regarding saving the environment, wilderness areas and endangered species. Students will be able to:
Materials: Overview of Week (homework and activities),Homework assignment sheets, Vocabulary, large poster of endangered species list, library books on the environment and endangered species.
HUMAN/ENVIRONMENT INTERACTIONS Review (Monday - 10 minutes)
Five Themes of Geography:
Introduction
1. Wilderness for Tomorrow (Monday night homework - 20 min.)
2. Endangered Wildlife (Tuesday in class)
3. Environmental Vocabulary (Tuesday night homework - 20 minutes)
4. Saving the Endangered ( Wednesday night homework - 20 minutes. Research species of your choice.
Teacher may review five main themes of geography (including the two the class has just covered, Place and Location.)
Lesson introduction When I was ten, my family moved to Oregon where my father raised blue-lake green beans in the traditional manner for that time with pesticides and herbicides. Then he read Rachel Carson's Silent Spring and became an organic farmer.
Wholeness for the lesson
To save/protect the environment (deep ecology) including wilderness (deep time) and all species, we must:
Main Points
1. Scientists identify over 1.4 million species of plant and animal life and estimate the earth may have more than 30 million living species. 2. Man kills off entire ecosystems daily, leading to the loss of tens of thousands of species each year. 3. At this rate, scientists estimate that over one fifth of earth's life forms will be lost forever within the next 30 years! 4. Common reasons for loss of wildlife include:
5. Environmental success stories include that of the bald eagle, and more recently, the northern spotted owl and West Indian manatee. 6. People are becoming educated and more involved. 7. The future of our wildlife rests in our hands - the current and future generations.
What difference does it make? Who cares if a few species are lost? Does the end (progress) justify the means (destruction to environment)? Today, environmentalists are taking positive steps to ensure:
Benefits of wilderness of man:
Procedures and activities Each day will begin with a review . Then, in small groups or in pairs, students will go over the worksheet (see four worksheets) that they have completed the night before , giving them the opportunity to teach each other and go over the content several times. Teacher walks around answering questions and clarifying group process.
Fulfillment.Teacher compliments class on their good work, good ideas, asks them to share what they've learned. Students present to the whole class (group poster/ skit/interview on Environmental vocabulary and individual reports on Endangered species.)
Closure. Teacher asks what conclusions, or patterns can be seen in what has been covered in past few days.Teacher summarizes, ties it back to the original wholeness and to the ideas of problems/solutions, parts/wholeness, diversity/unity.
Homework. Each night, students have 20 minutes of homework (see schedule)
Assessment strategies
Self-Reflection
I thought the boys took very well to the small group cooperative learning format, even without formal teambuilding exercises. They also seemed to like the quick-paced dividing into pairs and giving each other little talks. They did very well on their final reports. a special triumph was a boy who didn't interat very well with his group yet with encouragement ended up giving one of the best group presentations (in an interview format) with very rich content and interesting delivery. In further experiences with student teaching I will continue with the cooperative learning, at least for part of each period. I also want to add some modeling work (with clay) whenever applicable.
ENVIRONMENTAL VOCABULARY
Ozone depletion - "The ozone layer is an essential protective filter in the upper atmosphere that surrounds the Earth. As long as human life has existed, it has protected us from harmful ultraviolet rays coming from the sun. When these rays get through the atmosphere, they damage crops, destroy living cells and cause skin cancer. During the last 20 years, ozone levels above Antarctica have decreased by nearly 40% each springtime. It's all caused mainly by our use of chloro-fluorocarbons (CFC). Most countries have stopped industry using these in aerosols but they are still used in other products. The consequences are catastrophic: about 100,000 people die each year from skin cancer. It's especially bad in the southern hemisphere. There is truly no more time to wait: All CFC-use must be stopped immediately!" - Polish Ozone Group.
Greenhouse effect. Caused when some gases (produced when fossil fuels are used) allow sunlight to reach the ground, but prevent the sunlight's heat from rising out of the atmosphere and flowing back into space which subsequently causes average temperatures to rise. The main greenhouse gas is carbon dioxide and we are releasing more and more of it into the atmosphere - 500 billion tons last year. Oceans and forests soak up carbon, so we should hang on to them and stop producing it.
Acid rain. This pollutant forms when moisture in the air combines with nitrogen oxide and sulfur oxide released by automobiles, by factories, by power plants that burn coal or oil. The reaction between the moisture and the chemical compounds produces nitric and sulfuric acids, which fall to the earth with rain or snow. The acids pollute lakes and streams, resulting in the death of fish and the contamination of drinking water. They can also harm the crops and reduce the fertility of the soil. This form of pollution may even damage buildings and statues. In addition, acid rain pollutants may travel long distances, even reaching other countries.
Watershed pollution
Creative recycling
Radon pollution
Gridlock
Global warming
Eating lower on the food chain
Overpopulation
Ecotourism
