7. Environmental Literacy Research Group A K-12 LEARNING PROGRESSION TO SUPPORT UNDERSTANDING OF WATER IN THE ENVIRONMENTBeth Covitt & Kristin GunckelCCMS Knowledge Sharing InstituteJuly 10, 2006 MICHIGAN STATE UNIVERSITY

8. TRACING WATER IN ENVIRONMENTAL SYSTEMS What to know about “tracing water and other substances” • In environmental systems, water usually exists as a mixture • When moving through systems, water carries other substances • Substances “picked up” by water occur naturally or are result of human action • Humans prefer to find and use water with few added substances • Humans treat water to minimize harmful substances before/after use • Humans return used water to natural systems. Water travels through water cycle and is reused by humans and other species.

9. PRINCIPLES, PROCESSES and SYSTEMS • One facet of water literacy is that… • Students can apply FUNDAMENTAL PRINCIPLES • (e.g., structure of connected human & natural systems) • to PROCESSES IN SYSTEMS • (e.g., tracing water & other substances through systems) • Examples • Groundwater • Landfill Contamination • Watersheds • Ocean Water • Human Water System

10. SOME QUESTIONS NOT ADDRESSED TODAY • Watersheds • If a pollutant is put into a river at Town C, which towns will be affected? • Ocean Water • Why can’t we drink clean ocean water without treating it first? • How could you make ocean water drinkable? • Human Water System • Where does water come from before it gets to your house? • Where does it go after your house?

11. GROUNDWATERDraw a picture or explain what it looks like underground where there is water.

12. GROUNDWATERDraw a picture or explain what it looks like underground where there is water. Example from High School

13. LANDFILL CONTAMINATIONCan a landfill (garbage dump) cause water pollution in a well?

14. LANDFILL CONTAMINATIONHow could a landfill contaminate a well?

15. Environmental Literacy Research Group KEY FINDINGS: PROGRESSION IN STUDENT UNDERSTANDING OVER TIME • Increasing understanding of complexity of systems BUT invisible parts of systems remain invisible Water as mixtures; transport substances Groundwater, watersheds, atmospheric systems Connections between natural & human systems • Increasing understanding of need for processes & mechanisms, BUT how these mechanisms work & constraints on processes remain poorly understood. Evaporation, condensation Treating water • Increasing awareness of scales, BUT little success in connecting accounts across different levels Macro-Large Scale: Watersheds

16. Environmental Literacy Research Group DEVELOPING A CARBON CYCLE LEARNING PROGRESSION FOR K-12 MICHIGAN STATE UNIVERSITY

17. Applying fundamental principles… Structure of systems: atomic-molecular (CO2 and organic materials), single-celled and multicellular organisms (producers, consumers, decomposers), ecosystems Constraints on processes: Tracing matter: inorganic to organic forms …to processes in coupled human and natural systems Physical Change of Dry Ice Burning Match Losing Weight Plant Growth PRINCIPLES, PROCESSES and SYSTEMS

18. Environmental Literacy Research Group TRACING CARBONIN ENVIRONMENTAL SYSTEMS Living systems follow the basic principles of physical and chemical change, including conservation of mass and conservation of atoms Organisms are made mostly of water and organic substances Organic substances consist of molecules with reduced C plus H, O, and a few other elements Virtually all reduced C is created from CO2 and H2O through the process of photosynthesis Virtually all organisms get their energy by oxidizing reduced C compounds in cellular respiration The products of cellular respiration are CO2 and H2O Summary: CO2 + H2O + minerals with N, P, etc. Organic substances + O2 CO2 + H2O + minerals photosynthesis c. respiration

19. Environmental Literacy Research Group Dry Ice CONSERVING MASS DURING PHYSICAL CHANGE A sample of solid carbon dioxide (dry ice) is placed in a tube and the tube is sealed after all of the air is removed. The tube and solid carbon dioxide weigh 27 grams. The tube is then heated until all of the dry ice evaporates and the tube is filled with carbon dioxide gas. The weight after heating will be: a. less than 26 grams. b. 26 grams. c. between 26 and 27 grams. d. 27 grams. e. more than 27 grams. Explain the reason for your answer to the previous question.

20. Environmental Literacy Research Group Dry Ice CHANGE OF STATE • “Because going from a solid to a gas, it weighs less” • “Because of the law of conservation of mass”

21. Environmental Literacy Research Group BURNING MATCH What happens to the wood of a match as the match burns? Why does the match lose weight as it burns?

22. Environmental Literacy Research Group LOSING WEIGHT A person on a diet lost 20 pounds. Some of his fat is gone. What happened to the mass of the fat? • “As mass is converted into energy for energy for use, it has to go somewhere. This energy is used to power the body and the fat (now transformed to energy) is spent and no long in the body” • “I think it is turned into energy and it also comes out by it turning into water or gas” • “it will come out of the large intestine” • “the person sweats”

23. Environmental Literacy Research Group LOSING WEIGHT A person on a diet lost 20 pounds. Some of his fat is gone. What happened to the mass of the fat?

24. Environmental Literacy Research Group PRINCIPLES, PROCESSES and SYSTEMS • The fundamental principle of tracing matter is not being applied by students. • Few students understand gases as products or reactants in cellular respiration • Students frequently interconvert matter and energy. • Many students saw “fat burning” as a process involving “breaking down”, but did not trace it to a chemical process of oxidation into CO2 and H2O in cellular respiration

25. Environmental Literacy Research Group PLANT GROWTH A small acorn grows into a large oak tree. Where do you think the plant’s increase in weight comes from?

26. Environmental Literacy Research Group PRINCIPLES, PROCESSES and SYSTEMS • The fundamental principle of tracing matter is not being applied by students. • Few students understand gases as products or reactants in photosynthesis. • Students frequently saw water and soil nutrients as the critical source of plant weight.

27. KEY FINDINGS: FROM YOUNGER TO OLDER STUDENTS, WE SEE PROGRESS… • From stories to model-based accounts • Shift from why to how--purposes to mechanisms • BUT lack knowledge of critical parts of systems • From macroscopic to hierarchy of systems • Increased awareness of atomic-molecular and large-scale systems • BUT little success in connecting accounts at different levels • Increasing awareness of constraints on processes • Increasing awareness of conservation laws • BUT rarely successful in constraint-based reasoning • Increasing awareness of “invisible” parts of systems • Increasing detail and complexity • BUT gases, decomposers, connections between human and natural systems remain “invisible”

28. Environmental Literacy Research Group TO DO LIST • Systematic review of literature • Better assessments - for inquiry (Practice 1) - for applications to citizenship (Practice 4) - Psychometric quality (BEAR assessment system) • Understanding pre-model-based reasoning in elementary students (and all of us) - Embodied reasoning and inquiry - Storytelling and scientific accounts • Teaching experiments at upper elementary, middle school, and high school levels

35. OCEAN WATERHow could you make ocean water drinkable?

36. THE HUMAN WATER SYSTEMWhere does water come from before it gets to your house? And where does it go after?

37. THE HUMAN WATER SYSTEMWater Treatment • Most students do not mention water treatment • More of elementary & middle mention treatment before • More of high school mention treatment after

38. THE HUMAN WATER SYSTEMWater Recycling in the Human System • 40 percent of high school students indicate that water recycles
