Turn in Biosphere Squares at LAB STATION 1 • Take out your SCIENCE JOURNAL
Entry 11 2/8 • Explain the INTERDEPENDENCE found within an ecosystem. • When explaining your answer be sure to include the carbon cycle, energy transfer, and biotic relationships
Find your new seat and take out your journal and chrome book New Seats
Entry 13 9/13 • Log on to the following web address and find out your CARBON FOOTPRINT • http://bit.ly/Tg0H1O • Then in your journal describe what a carbon footprint is, Tell me what your carbon footprint is from the calculator and how you think you can reduce it.
Help!!!!! Unit 3 Human Impact
More people Bubble Chart • As a group make a bubble chart with ALL of the possible effects of a growing population will have on the environment and society as a whole • MORE people might mean…. Human Population Growth
Human Population GrowthToo many people = environmental problems! • What caused human population growth? • Causes: • Agricultural Revolution- more food to support more people • Industrial Revolution- improvements in technology, and medicine, increased birth rate and decreased death rate • Urbanization – development of cities, economic and social development
Effects of Human Population Growth • Overcrowding • Increase in pollution- ALL environmental problems relate back to human overpopulation! • Decrease of Natural Resources: More people require more resources • Increase land use
Solution: • Zero Population Growth: birth rate = death rate; china offers tax incentives for having one child; education, birth control • Conservation: wise and careful use of resources • Reduce: use less materials • Reuse: use products more than once • Recycle: return products to be reprocessed • Sustainability – ensuring the availability of resources and a stable environment for future generations.
What’s in a Histogram? Ages, percent of males and females in the populationWhat can a histogram reveal? An increasing, stable or decreasing population
Ticket Out the Door • 1. Name 2 events that created a huge increase in human population • 2. List two solutions to environmental issues caused by human population • 3. Use the histogram to determine if the population is increasing or decreasing. Explain how you know.
Entry 14 9/16 Human Population vs. Environmental Problems Describe the connection between Human Population & Environmental Problems.
RESEARCH news articles and opinion pieces on human population trends and related environmental and social issues. See the topics below. Each person should sign up for ONE topic to research. • Within your group there should be at LEAST ONE article summary related to global issues , one article summary related to a LOCAL issue. • Cite your source on the index card. Write a summary (in YOUR OWN words) on your card explaining the MAIN ideas of the article. (How does overpopulation of humans relate to this environmental issue?) Tape or paste these cards onto your bubble chart. • Air pollution • Land use • Climate change • Migration/Immigration • Deforestation • Public health • Social security • Energy • Waste management • Food resources/Hunger • Water resources • Housing and homelessness • Economics • Resource use/Consumption • Endangered species

Entry 13 2/12 Use the picture to write a definition and draw a picture to represent the word BIODIVERSITY
Global Warming: unnatural warming of the Earth • Cause: Excessive greenhouse gases (carbon dioxide CO2 and methane CH4) in the atmosphere trap heat, leading to an abnormal increase in earth’s surface temperature • CO2 comes from burning fossil fuels • CH4 from landfills and cow farts!
Effect: It’s like the earth has a fever!Have you seen the movie “ The Day After Tomorrow”? • increase in temperature (2-4 degrees Celsius), weather patterns will change worldwide, polar ice caps may melt, flooding coastal cities and contaminating drinking water with saltwater.
Ozone Depletion: Has nothing to do with global warming! • Cause: CFCs (chlorofluorocarbons), once used as refrigerants and in aerosol cans destroy ozone molecules in the upper atmosphere leading to thinning or a hole UV radiation is NOT heat!!!!
Ozone depletion : • Effects: Harmful UV radiation reaches earth causing increased numbers of sunburns, skin cancer, cataracts (leading to blindness), and crop damage.
Group Global Warming Activity • Each group has a different topic describing one effect of global warming. • In your folder you have: • A copy of an article for each person to read • Each person will answer the questions on a separate sheet of paper in complete sentences… in your OWN words. • Each person will draw and complete the graphic organizer on their own paper. • Each group will creatively display the information from their graphic organizer in the educreation app (take a picture of the graphic organizer and each person explains a portion) Each person is expected to speak/talk about their topic. Hi this is _________ and I am going to explain _______. **implications means consequences jennifer.wells-lewis@cms.k12.nc.us password is : students
Interpreting the graphic organizer • Cause (what is the reason for the situation) • Event (what is happening as a result of the cause) • Effects (the result) • Implications (consequences) • Solutions (how can we fix this problem)
Entry 14 2/13 • Seven students argued about what they thought were the major human causes of global warming. Here is what each of them thought:: • Maria: acid rain • Natalie: burning coal • Tessa: the fuel we use in our cars • Anita: toxic chemicals in air pollution • Raul: the thinning of Earth’s ozone layer • Van: the growing landfills • Blaine: the CFC’s from refrigerators • Write out the causes that you agree with. Explain why you agree.
Ticket Out the Door 1. What three events allowed for the fast growth of human population? 2. What type of curve does human population growth look like when graphed? 3. Is the Country pictured in the Histogram a stable or developing country? 4. What is the cause of Global Warming?
Entry 15 9/17 CLIMATE FORUM • Please take out your questions and flowchart from yesterday.
Acid Rain • Cause: emissions (sulfur and nitrous oxides from cars and factories react with oxygen and water)
Acid Rain: • Effects: A lowered pH disrupts aquatic ecosystems, makes soil less fertile, harms plant life, and damages human property.
Water Quality • Cause: sediments, oil, fertilizers from land, illegal dumping, acid rain, raw sewage, heated water from power plants • Effect: Disease, habitat destruction
Biodiversity Loss/ Habitat Destruction • Causes: • Deforestation: cutting down forests for wood, and farming • Draining/filling wetlands • Bioaccumulation: • Greatest accumulation in lower organisms in the food chain • Biomagnification • Magnified greatest in organims higher in the food chain • Endangerment/extinction: Endangered species are at risk of becoming extinct. Extinction refers to the loss of a particular species. http://www.youtube.com/watch?v=E5P-UoKLxlA
Invasive Species • Invasive Species - is non native organism which causes economic or environmental harm • Humans spread invasive species through • Trade • Agriculture • Biological • Pets • Accidental
Invasive Species • Invasive species can cause harm to native species • Superior predator/out compete • can overcrowd an organism • can prey on an organism • What are two reasons invasive species can spread so rapidly • no natural predators • utilize unused resources
Invasive Species • Ecological impacts caused by invasive species • reduces biodiversity and reduces resources available to natives • Economic impacts caused by invasive species • management can cost up to $140 billion annually • Control of invasive species • Careful ling introducing species to control population • Pesticides • Tilling the land
Technology • Satellites: track changes global temperature and the ozone layer • Ice Core Analysis: Measure gases (CO2) that were once in atmosphere • Census Data:
Census Data: Developing Stable
NC Environmental Issues • Read the article to identify the problem • Log on to Google Drive and PULL UP YOUR CLASS PERIODS PRESENTATION. • Each member will perform a task. Assign on person to each slide – Be sure to include your name on your slide. • If you DO NOT HAVE A SLIDE – you will complete the following… • Add an additional slide to the presentation explain how humans have played a role in creating this environmental issue and if it can be tied to human population growth • Be sure to add your name to your slide
