1. Cambridge IGCSE Environmental Management 2024-2026

2. Overview of the IGCSE exam Learners taking Cambridge IGCSE Environmental Management must complete two written papers. Paper 1 Theory consists of two sections. Section A contains short-answer and structured questions. Section B contains short-answer and extended response questions based on source material. Paper 2 Management in context contains short-answer, data processing and analysis and extended response questions based on source material. Learners must answer all questions on each paper. There is no coursework.

3. Overview of the IGCSE exam Assessment objectives To achieve success in their course, learners must demonstrate three different types of skill. AO1 Knowledge and understanding . display factual knowledge about the syllabus topics demonstrate that they understand the concepts. AO2 Information handling and analysis . process and analyze unfamiliar information perform mathematical calculations on data draw supported conclusions. AO3 Investigation skills and making judgements . plan and carry out investigations draw conclusions from their results also evaluate their methods.

4. Why do we need to Manage Resources?

5. If you have all the resources on the planet, HOW do you manage them?

6. District 1: Luxury   District 2: Masonry   District 3: Technology District 4: Fishing   District 5: Power (Electric, solar and nuclear)   District 6: Transportation District 7: Lumber   District 8: Textiles   District 9: Grain   District 10: Livestock   District 11: Agriculture District 12: Mining   District 13: Graphite You COULD manage the resources like THE HUNGER GAMES http://hashtagmaine.bangordailynews.com/2015/10/27/the-internets/if-the-hunger-games-is-set-in-a-future-north-america-maine-is-in-this-district-should-it-be/

7. Why is it so complicated? Social Economic Political Environmental Human Health Cultural, Science, Religion, others? Poverty, Supply & Demand, Opportunity, Local & Global Economies, others? Local, State, National & International Laws, Acquisitions/Wars, others? Social Justice, Cancer, Viruses, Pesticides, others? Animal Welfare, Agriculture, Pesticide Availability, others? SUPERWEEDS DO YOU HAVE A RIGHT AS A LIVING BEING TO CLEAN WATER, CLEAN AIR, & CLEAN FOOD?

8. What do you know about BPAs? One generation ingests, two generations “feel.” www.niehs.nih.gov/recovery/critical/docs/bpa-signature-project.pdf

9. Bisphenol A (BPA) Used for more than 40 years Hard plastic food containers Baby bottles Reusable cups The lining of metal food and beverage cans (including canned liquid infant formula)  Trace amounts of BPA can be found in some foods packaged in these containers. http://www.hhs.gov/safety/bpa/

10. MAKE A LIST RIGHT NOW OF EVERYTHING YOU CAN SEE THAT IS PLASTIC!

11. Environmental Management Defined Environmental management (noun): (a)  manipulation of the physical or social environment of a person or group;  (b) management of human impact on the environment, especially with the intention of preserving natural resources. OED (2013)

12. Environmental Management Study of Resources Includes Physics Chemistry Biology All systems Organism Population Community Ecosystem Biosphere These are biotic? What about abiotics?

13. LET’S PLAY A GAME! FAll Back in case video game not working Rules: You  may not  talk to anyone during the game or communicate with hand or facial gestures. The chips belong to all of you—to the group. Music will be played, and while it is playing, each of you may take chips out of the pool of chips in the center. You may not put chips back into the pool once you have taken them out. As soon as the music stops, you must stop taking chips out of the pool. At that time, I will double the number of chips left in the pool, and then we will continue the game. At the end of each round, players who have 10 chips may trade them in to me for a piece of candy. If you have fewer than 10 chips, you will not get candy. There will never be more chips in the pool than there were at the start of the game. This is the maximum number of chips the pool can hold. https://www.sciencefriday.com/educational-resources/one-for-all-a-natural-resources-game/ ELECTRONIC GAME FOR COMPUTER OR PHONE Unit Zero Key Skills, Activity #4 Watch Video then play game: https://www.ecoocean.de/the-game/

14. What is Science? Science is based on “knowledge” or “skill” Debate of what science is: Is it mathematical? Who has the knowledge? Scientist? Laymen? Does it depend on what the general population believes? Does science change? How is that knowledge verified? Scientific Method: Francis Bacon (1561-1626) “Baconian Method” PseudoScience

15. Scientific Method “Baconian Method” Hypothesis Prediction and testing Experimental Design Rigorous Testing Duplication Sir Francis Bacon 1561-1626

16. Scientific Method NULL Hypothesis- DISPROVE/REFUTE a proposed explanation of an observation Is a statement NOT a question that expresses the expected answer to the problem statement (what you think the results of the experiment will show) Example: Plant growth rate is unaffected by the presence of cadmium in the soil

17. Scientific Method ALTERNATIVE Hypothesis- PROVE/SUPPORT a proposed explanation of an observation Is a statement NOT a question that expresses the expected answer to the problem statement (what you think the results of the experiment will show) Example: Plant growth rate is affected by the presence of cadmium in the soil

18. Scientific Method 3 parts to an experiment Control-standard for comparison Variables Independent Variable Dependent Variable Constants =parts of your experiment that do not change

19. Scientific Method Intro w/ Null Hypothesis Literature Review Methods Data Results Discussion Conclusion Bibliography How would you find out what is causing THIS?

20. Scientific Method Null Hypothesis Organize your readings and find themes Design Experimentation GO OUT AND COLLECT DATA Analyze Data Synthesize Results and compare to existing research Does your data support or refute existing data? Draw Conclusions SHARE WITH PROFESSIONALS & COMMUNITY MEMBERS

21. Lab Period One: Appropriate Scientific Sources First Lab Period:  Who determines what is valid scientific results? What are primary, secondary, and tertiary sources? How do you read a peer reviewed journal article? How do you find appropriate sources (library) Homework:  Find peer reviewed article and write a summary in electronic journal   (2-3 sentences)

22. How do you discern between good and poorly performed science?

23. Acceptable Resources Primary Original source or evidence Peer reviewed journal articles Secondary Cite, comment on, or build upon primary sources Books, scientific magazines Tertiary Compilation of primary and secondary sources

24. How you do discern acceptable resources? In a small group check the resources on your desk. Which are acceptable for scientific research?

25. The Nature of Science Ethics in experimentation additional video Science Changes
