TRANSCRIPT

  • Earth as a SystemOcean Science

  • IMPROVEMENTSAlso need more questions/info on albedoOceans, albedo of oceans vs. iceMore information on spheres interactingMore explicit thing where we trace energy from sourcesmaybe a worksheet. Article where students identify changes in spheres and interactionsabout earthquake or somethingTalk about how your body is made of what you eatget equations for making fats & stuff, and where in your body is phosphorous? Pertains to cyclesMore about formation of Earth & layers of Earth (Earths interior), maybe magnetic field!! That energy is cool Video/more information on nuclear fusionUse Newton's cradle, dominoes, other things where energy transfers to show energy transfer

  • IMPROVEMENTSHole in ozone not = global warmingBring in a teapot!Suns heat doesnt reach EarthNebular theory different than big bangEarth is not hot inside because of lava! (theres lav)Does sun keep core hot?Chocolate chip cookie is misleading as it leads kids to think Earth is all molten insideSun isnt burningMore on explaining how wind is created by sunMore examples of stuff?Nuclear fusion DOESNT occur inside Earth!Include the cycles on the quiz (seasons is next for weather sci)

  • ClosureWhat are the 3 rules of this classroom?What will students do at the beginning of class tomorrow?

  • Bell Ringer 1/22/14 4 minGet a sheet of notebook paper and format it as seen to the left of this screen. C.S. = COMPLETE SENTENCEList the 3 classroom rules in their entirety. Write at least one question about oceans or water that you would like to have answered in this class. (c.s.)

(magnets & string!)Mechanical Potential EnergyElastic potentialGravitational potential

  • Energy is Everywhere!

  • Energy TransferMatter & energy cannot be created nor destroyed, but they can change forms.Energy is constantly being transformed.Look for types of energy & energy transformation in the following video.Ok Go video

  • Energy TransferNewtons Cradle

  • Power PlantsPower plants convert energy into electricity, usually by turning turbines.When a magnet moves past a wire, electron flows through the wire (electricity).A turbine is like a big fan thats turned by the steam. Its attached to a wheel with magnets on it.Coal Power Plant Videohttp://www.youtube.com/watch?v=SeXG8K5_UvU Only power plant w/out turbines: solar powerWhere does our electricity come from?Magnet & Flashlight!http://www.youtube.com/watch?v=gSjL8FOZVeUhttp://www.mechanicalengineeringblog.com/tag/wind-up-flashlight/

  • Do turbines make energy?What causes them to spin?

  • ClosureDefine matter in your own words. Define energy in your own words. What is the matter & energy in:A moving car on a bridge

    The computer

    Lightning

  • Know It AllElectricity is often cheaper at night, so thats when you should do your laundry!

  • ObjectivesSWBAT identify Earths 3 energy sourcesSWBAT explain why/how the sun shinesSWBAT explain the origin of geothermal energySWBAT define albedo and predict the relative albedo of surfacesSWBAT trace energys path as it travels through the Earth system

  • Earths 3 Main Energy SourcesSolar Energy (Sun)Geothermal Energy (Earths Interior Heat)Tidal Energy (Moons motion around Earth)

  • Solar Energy 99.985 % of Earths energy enters as solar energy.Source of energy for almost all living things.

  • Solar Energy Where does the suns energy come from?A process called nuclear fusion hydrogen atoms are fused together to make helium

  • Nuclear FusionExtreme heat & pressure in center of sun pushes hydrogen atoms togetherHydrogen atoms combine to form helium atoms & energyThis is matter turning into energy (electromagnetic waves)! 600 lbs of H 596 lbs of He + energy!After a million years or so, the energy reaches the surface of the sunFrom there, the energy takes about 8 minutes to reach Earths surface.

  • Nuclear Fusionhttp://www.youtube.com/watch?v=pusKlK1L5To

  • Albedo Percentage of suns energy reflected by an areaAlbedo comes from a Latin word meaning white

  • Albedo Forest have an albedo of about 5 to 10 %. They reflect about 5-10% of the sunlight they receive.

  • Deserts - 30% albedoThey reflect about 30% of the suns energy.

  • Oceans 6% albedoThey reflect about 6% of the suns energy.

  • Sea Ice 50-70% albedoIt reflects 50 to 70% of the suns energy.

  • Snow fields 80 - 90% albedoThey reflect 80 to 90% of the suns energy.

  • Geothermal Energy The thermal (heat) energy inside of Earth 0.013% of Earths energy

  • Geothermal EnergyCauses tectonic plates to move, making earthquakes, tsunamis, volcanoes, and mountainsCreates geysers.

  • Geothermal Energy Source of energy for a few types of organism on Earth! (deep in oceans)Chemosynthetic bacteria, tube worms, spider crabs, musselsMay be wherelife began!

  • Geothermal EnergyWhy is Earth hot inside?Heat leftover from formationRadioactive isotopes decaying uranium, thorium and potassium Matter turning into energy again! (Everybody wants to be iron.)

  • Geothermal EnergyTrue or False?The inside of Earth is filled with lava.Earth is hot inside because its full of lava.Earth is hot inside because of nuclear fusion.Earth is hot inside because radioactive matter is decaying.Earth is hot inside because its still cooling from when it formed 4 billion years ago.

  • Tidal Energy Smallest part of the energy budget (0.002%)Caused by gravity of moon & sun and Earths rotationMoon stronger thansun cuz its closer

  • Which energy source causes?

  • How did the energy get here?Rain falls

    Firewood is burned

    Asian goose flies

  • How did the energy get here?

    Wind blows

    Music from computer

  • Bell Work 9/4/13Which kind(s) of energy do the following objects have? (light, chemical potential, kinetic, heat, gravitational potential, electrical, sound)

    Barking dogBook on fireHow did the heat energy get in this room? Trace it back to its source.

  • Bell Work 9/5/13Get & sharpen pencil (or you can use a pen)Leave an empty seat between you and the student next to you if possible.Study for 3 minutes.When timer sounds, put your notes away & take everything off of your desk.Listen to test instructions.

  • Bell Work 2/5/13 5 minGive an example of how the atmosphere affects/interacts with the other 3 spheres (biosphere, geosphere, hydrosphere).

  • HydroGeoBioAtm.

  • On Tuesdays Quiz

    Define energy & matter and give types/examples of each.Why does the sun shine? (detail)What is albedo? Give an example of something with a high albedo and something with a low albedo.Why is Earth hot inside? (2 reasons)What 3 things cause tides?List the 3 sources of Earths energy.Which energy source powers the following?List the matter and energy in objects/events, like demosHow did this energy get here? (1)Turbine how works, what is

  • Bell Work 2/7/13 2 minHow might a volcano erupting (geosphere) affect the other spheres (b, h, a)?

  • Cutting trees along a river.

  • Bell Ringer 9/5/13 2 minQUIZ!An earthquake caused a tsunami in Japan in 2011. Ocean currents carried debris from Japan to all of the shores of Alaska. Now animals are eating the debris. Identify the sphere interactions occurring.

  • Earth As A System

    Earth is a systemSystem group of interacting parts that act as a wholeParts affect each other

  • AtmosphereThe envelope of gases surrounding Earththe air we breathProtects living things from suns radiation & meteorsProvides O2 (oxygen) and CO2 (carbon dioxide) to living thingsOnly planet in solar system w/ O2

  • Geospherethe solid Earth itselfRocks, mountains, beaches, mineralsCrust, mantle, outer core, inner core

    Always slowly changing, sometimes quickly

  • HydrosphereAll of the water in the Earth systemOceans, lakes, rivers, glaciers, snow, rain, groundwater, clouds3% fresh water, 97% salt water30% of fresh water is liquid & available to humans (the rest is in frozen ice caps)Water on Earth is continually recycledWater cycle!

  • BiosphereAll life forms plants, animals, bacteria, people

  • Sphere InteractionThe four spheres are constantly changing, moving, and interacting together.The actions of one sphere often affect others

  • As part of the biosphere, how do plants affect the other spheres?Plants (biosphere) draw carbon dioxide from the air (atmosphere) and water (hydrosphere). They release oxygen and water vapor, and then may be eaten by animals (another part of the biosphere).

    Where does the energy in plants come from?

  • Volcanoes erupt sending ash & gases into the air. Ash & lava come down onto forests, destroying some animals habitats. Large eruptions can cause mini ice age by blocking out the sun, cooling the oceans.

    Where does energy in volcanoes come from?How do volcanic eruptions affect the other spheres?

  • How do hurricanes affect the other spheres?

    Hurricanes sweep across the ocean and onto the land, damaging the dwellings of people who live along the coast & causing erosion.

    Where does energy in hurricanes come from?

  • Burning Fossil FuelsBurning fossil fuels adds carbon dioxide to the atmosphere, which traps more of the suns energy. The air becomes warmer, then the ocean becomes warmer. Coral reefs that are sensitive to temperature changes die. Some organisms that depend on coral reefs also die.
