Transcript of Performance Task for Science III

Presentation of Group III "Ecosystem and Saving the world" What is an Ecosystem? An Ecosystem is a system where every organism is
collaborating with each other. There are different kinds of Ecosystems These are just few examples. There are a lot more in our world. WAIT How does knowing these things help us save the world? We have 2 classifications of Ecosystems A BALANCED one (cc) photo by medhead on Flickr And (cc) photo by medhead on Flickr An UNBALANCED one Analogy to students HAve a look at this drawing Sun That produces SUNLIGHT Ecosystem AIR SOIL WATER That's how simple it is. Students Teachers Lessons Enduring Understanding = Plant = Water = = School = Soil Sunlight Air All of these elements work
together in order the plant to
grow and in order to have a
BALANCED ECOSYSTEM CRITERIA n. pl. cri·te·ri·a or cri·te·ri·ons -A standard, rule, or test on which a judgment or decision can be based. What are the criteria for an UNBALANCED ECOSYSTEM? How about for the BALANCED ECOSYSTEM? SOLUTION? SOLUTION? SOLUTION? SOLUTION? CONCLUSION: Thank you for listening We hope that you understand something Reporters: Kim Dalanon
and Queenie Evangelista Researchers: JC Guerrero Joyce Montano Blessa Pura Louise Anorico With Special Help of: Renan Quintana and Raymond Orquiza Unbalanced 1.Insufficient Number of Trees Reason for Global Warming
Factor for Floods, Landslides, and Strong rains
Reason for lack of habitats and lack of food of some animals which results in extinction Balanced 1. Sufficient Number of Trees Stable Sustainability of life
Less calamities due to lower temperature Every family in the Philippines plants at least 2 trees a year.
The total population of the Philippines as of May 1, 2010 is 92,337,852
And let's say that an average Filipino family have 5 members. Then, we have approximately 18,467,570 families.
Then if every family plants 2 trees a year, then we'll have approximately have 36,935,140 trees annually. But of course, this is way too impossible. The numbers are just there so you can visualize how POWERFUL this tree planting method is. Balanced Unbalanced 2.Uncontrolled Garbage Production Another Factor of Floods
A big producer of methane
Source of diseases and contributes to different
kinds of pollution 2.Controlled Garbage Production Less floods
Safer air
More Eco-Friendly environment Unbalanced Balanced 3.Congested number of people in a certain area Over-usage of resources
Irresponsibility 3.Nice distribution of people controlled and right usage of resources
More people have the chance to have a job
A more responsible community Unbalanced Balanced 4.Uneducated people Undisciplined
We wouldn't know what to do 4.Educated people Disciplined
And know what actions to take The triple R Reuse Reduce Recycle As a chemistry student, we can invent new methods of lessening these garbage HELP the Government to economically,industrially, and independently DEVELOP undeveloped places here in Philippines. EDUCATE more.
Use your knowledge as a high school student to EDUCATE.
Use your knowledge as a CHEMISTRY STUDENT to EDUCATE.
All the possibilities are possible because of us students.
We are LIGHT of TOMORROW. To conclude this presentation,
we believe that, everything that happens right now, has a reason. And now, the reason for these are for us to change for the better.
Don't speak. Act. The flora (vegetation) and the fauna (animals) characteristics of a woodland area comprise a forest ecosystem. Forest Ecosystem A marine ecosystem comprises the organisms within the ocean environment. Examples include temperate and tropical oceans, shorelines, lagoons and coral reefs. Marine Ecosystem Organisms living in rivers, lakes and streams are examples of communities living within a freshwater ecosystem. Freshwater Ecosystem Urban Ecosystem An urban ecosystem is the community of nonliving (buildings, structures and streets) and the living (humans and a few animals such as pigeons) within the same habitat. Agricultural Ecosystem An agricultural ecosystem, also known as an agroecosystem, is an ecosystem that has been domesticated. Farmland communities and the living and nonliving components within them, for example energy, machinery, irrigation and pastures, are agricultural ecosystems. Global Warming Landslides Strong Rains What is Methane? Methane is an odorless and colorless gas
If inhaled, it quickly displaces oxygen and cause asphyxiation
Methane is the principal component of natural gas and one of the most abundant organic compounds on Earth.
Highly explosive if concentrated
Found in most garbage sites
Methane is created near the Earth’s surface by a process called methanogenesis, the final step in the decay of organic matter. Congested number of people in an area Squatters area. A good example
of Unemployment, Irresponsibility
and Lack of Education . Last, but not the least Questions?
