  1. Global Warming: Presented by: Hafez Osman Lopez Ronald Raganit Merilles Earl Francis Cabugawan

  2. INTRODUCTION • Target audience: Secondary 2 – O ‘Level • Duration: 2 periods (1 hour) • OBJECTIVES: • The lesson is programmed to: • Extract relevant information about the causes and effects of global warming. • Create possible solutions in alleviating the causes and effects of global warming through the use of ICT tools.

  3. Background: Many people in this world are increasingly concerned about the effects of Climate Change especially Global Warming! As a concerned citizen, what would you do?

  4. Your task: • View the multimedia presentation. (Video, Animation, PowerPoint) • Identify and analyze the causes and effects of global warming based on the earlier slides. • Undertake separate activities pertaining to global warming using ICT tools.

  5. Concepts on Global Warming through Animation http://www.bbc.co.uk/climate/evidence/greenhouse_effect_img2.shtml

  6. INDIA: Dokriani Glacier retreated 66 ft despite of 1998 winter PHILIPPINES: Coral Reef Bleaching CANADA: Crumbling of permafrost TAIWAN: YEAR 2000 was the warmest temperature INDONESIA: Malaria spreads to Higher elevations. ANTARTICA: Penguin population decline by 33%; collapse of ice shelf

  7. ARGENTINA: Increase in population of pearlworts and hairgrass RUSSIA: Shorter Freezing period and wildfires threaten tiger habitat CHINA: Disappearing lakes COSTA RICA: Disappearing toads and frogs in Montaverde Cloud Forest AFRICA:Flourishing of mosquitoes PAKISTAN: Longest drought (1999-2001)

  11. How to prevent GLOBAL WARMING?

  12. WHAT YOU CAN DO?? Plant a treeA single tree will absorb one ton of carbon dioxide over its lifetime. Shade provided by trees can also reduce your air conditioning bill by 10 to 15%. Use a clothesline instead of a dryer whenever possibleYou can save 700 pounds of carbon dioxide when you air dry your clothes for 6 months out of the year Be sure you’re recycling at home You can save 2,400 pounds of carbon dioxide a year by recycling half of the waste your household generates.

  13. Buy organic foods as much as possibleOrganic soils capture and store carbon dioxide at much higher levels than soils from conventional farms. If we grew all of our corn and soybeans organically, we’d remove 580 billion pounds of carbon dioxide from the atmosphere! Reduce the number of miles you drive by walking, biking, carpooling or taking mass transit wherever possibleAvoiding just 10 miles of driving every week would eliminate about 500 pounds of carbon dioxide emissions a year! Eat less meat Methane is the second most significant greenhouse gas and cows are one of the greatest methane emitters. Their grassy diet and multiple stomachs cause them to produce methane, which they exhale with every breath.

  14. Activity 1: PODCAST using AUDACITY • Instructions: Working with partner (2-4), create a digital recording that explores one of the topics below: • The important facts about Global Warming • The causes and effects of Global Warming • Alternative methods and solutions on how to control Global Warming Click the icon for the Rubric on Podcast using Audacity

  15. Procedures: • Each group will create a structure and script for the podcast based on the chosen topic. • With your partner identify several points you wish to include keep in mind that your podcast has a five – minute limit. • Deliver the podcast in a conversational style. You may work from notes or use a prepared text. But the delivery should sound conversational not like a text being read. Practice, record, listen and monitor your delivery on the recording. Record again. • You should edit out unwanted pauses or small errors. • When the podcast has been recorded to your satisfaction export the file. Windows users, Windows users choose File>”Export as MP3.”

  16. Requirements: • Your podcast must be 4-5 minutes. Each person should speak approximately half the time. • Introduce yourselves in your group number at the beginning of the podcast and name yourselves again at the very end. Be sure to introduce the topic near the beginning of the recording. At the end give a brief summary and state your names again. • The final MP3 file that you submit should include the names of the group members. Click the icon for the Rubric on PODCast

  18. ACTIVITY 3: CONCEPT MAP using CMAPTools • Instructions: Create a Concept Map using CMAPTools : • Each group will construct concept map based on the lecture presented earlier on: • a. Causes and Effects of Global Warming. • b. Alternative methods and solutions on how to control Global Warming.
