Knowledge:
Students know:
  • Radiation from the sun (solar energy) introduces heat (thermal energy) into Earth's atmosphere, water, land, and ice.
  • Thermal energy exists in the atmosphere, water, land, and ice as represented by temperature.
  • Thermal energy moves from areas of high temperature to areas of lower temperature either through the movement of matter, via radiation, or via conduction of heat from warmer objects to cooler objects.
  • Absorbing or releasing thermal energy produces a more rapid change in temperature on land compared to in water.
  • Absorbing or releasing thermal energy produces a more rapid change in temperature in the atmosphere compared to either on land or in water so the atmosphere is warmed or cooled by being in contact with land or the ocean.
  • The rotation of Earth and unequal heating of its surface create patterns of atmospheric and oceanic circulation.
  • Patterns of atmospheric and oceanic circulation vary by latitude, altitude, and geographic land distribution.
  • Higher latitudes receive less solar energy per unit of area than do lower latitudes, resulting in temperature differences based on latitude.
  • A general latitudinal pattern in climate exists where higher average annual temperatures are found near the equator and lower average annual temperatures are at higher latitudes.
  • Latitudinal temperature differences are caused by more direct light (greater energy per unit of area) at the equator (more solar energy) and less direct light at the poles (less solar energy).
  • A general latitudinal pattern of drier and wetter climates caused by the shift in the amount of air moisture during precipitation from rising moisture-rich air and the sinking of dry air.
  • In general, areas at higher altitudes have lower average temperatures than do areas at lower altitudes. Because of the direct relationship between temperature and pressure, given the same amount of thermal energy, air at lower pressures (higher altitudes) will have lower temperatures than air at higher pressures (lower altitudes).
  • Features on the Earth's surface, such as the amount of solar energy reflected back into the atmosphere or the absorption of solar energy by living things, affect the amount of solar energy transferred into heat energy.
  • Landforms affect atmospheric flows (e.g., mountains deflect wind and/or force it to higher elevation, known as the rain shadow effect).
  • The geographical distribution of land limits where ocean currents can flow.
  • The Earth's rotation causes oceanic and atmospheric flows to curve when viewed from the rotating surface of Earth (Coriolis force).
  • Fluid matter (i.e., air, water) flows from areas of higher density to areas of lower density (due to temperature or salinity). The density of a fluid can vary for several different reasons (e.g., changes in salinity and temperature of water can each cause changes in density). Differences in salinity and temperature can, therefore, cause fluids to move vertically and, as a result of vertical movement, also horizontally because of density differences.
  • Ocean circulation is dependent upon the transfer of heat by the global ocean convection cycle, which is constrained by the Coriolis effect and the outlines of continents.
  • Because water can absorb more solar energy for every degree change in temperature compared to land, there is a greater and more rapid temperature change on land than in the ocean. At the centers of landmasses, this leads to conditions typical of continental climate patterns.
  • Climates near large water bodies, such as marine coasts, have comparatively smaller changes in temperature relative to the center of the landmass. Land near the oceans can exchange thermal energy through the air, resulting in smaller changes in temperature. At the edges of landmasses, this leads to marine climates.
  • Variations in density due to variations in temperature and salinity drive a global pattern of interconnected ocean currents.
  • Radiation is the transfer of heat energy by electromagnetic wave motion. The transfer of energy from the sun across nearly empty space is accomplished primarily by radiation.
  • Radiation from the sun (solar energy) introduces heat (thermal energy) into Earth's atmosphere, water, land, and ice.
  • Convection is the transfer of heat by a current and can occur in a liquid or a gas.
  • When air near the ground is warmed by heat radiating from Earth's surface. The warm air is less dense, so it rises. As it rises, it cools. The cool air is dense, so it sinks to the surface. This creates a convection current.
  • Convection is the most important way that heat travels in the atmosphere.
  • Convection in the atmosphere is responsible for the redistribution of heat from the warm equatorial regions to higher latitudes and from the surface upward.
Skills:
Students are able to:
  • Use a model of Earth and identify the relevant components of Earth's system, including inputs and outputs.
  • Describe the relationships between components of the model including how the rotation of Earth and unequal heating of its surface create patterns of atmospheric and oceanic circulation.
  • Articulate a statement that relates a given phenomenon to a scientific idea, including how the rotation of Earth and unequal heating of its surface create patterns of atmospheric and oceanic circulation.
  • Identify and describe the phenomenon under investigation, which includes how energy is distributed between Earth's surface and its atmosphere.
  • Identify and describe the purpose of the investigation, which includes providing evidence that energy from the sun is distributed between Earth's surface and its atmosphere by convection and radiation.
  • Collect and record data, according to the given investigation plan.
  • Evaluate the data to determine how energy from the sun is distributed between Earth's surface and its atmosphere by convection and radiation.
Understanding:
Students understand that:
  • Weather and climate are influenced by interactions involving sunlight, the ocean, the atmosphere, ice, landforms, and organisms. These interactions vary with latitude, altitude, and local and regional geography, all of which can affect oceanic and atmospheric flow patterns.
  • The ocean exerts a major influence on weather and climate by absorbing energy from the sun, releasing it over time, and globally redistributing it through ocean currents.
  • Radiation from the sun (solar energy) introduces heat (thermal energy) into Earth's atmosphere, water, land, and ice and is represented by temperature. Thermal energy moves from areas of high temperature to areas of lower temperature on Earth's surface and in its atmosphere either through radiation or convection.

Background/Preparation:

Teacher preparation: Teacher will need to set up heat lamp and globe in a central and safe location so students can see the investigation. 

Then, set up the following stations within the classroom: 

Radiation- Have this information for students to read: "Radiation is the transfer of heat energy by electromagnetic wave motion. The transfer of energy from the sun across nearly empty space is accomplished primarily by radiation. Radiation occurs without the involvement of a physical substance as the medium. The sun emits many forms of electromagnetic radiation in varying quantities."

Give students the example of a radio. While it is playing, it emits radio waves and that is an example of radiation. Have students list other forms of radiation. Students will record answers in their science notebook. Optional the teacher can have a radio that students can listen to. 

Conduction- Have the information from this link for students to complete. Students will need to highlight the examples of conduction and complete crossword puzzle. 

Convection-  With teacher assistance, students will observe convection taking place in the breaker. The teacher explain process of the heat rising and the creating of a convection cell. 

  Procedures/Activities: 

Step 1 Teacher will turn off lights and turn on heat lamp. Teacher will explain to students the lamp represents the Sun and the Globe represents the Earth. Teacher will ask students the following questions:

What does the Sun provide the Earth? 

How does that energy/heat transfer to the Earth?

How does the Earth's heat stay or Earth?

The teachers will inform students that energy is transferred in three different ways: radiation, conduction and convection and provide examples for each. 

Radiation- UV waves

Conduction- touching a hot pot

Convection- air blowing through a vent 

Step 2  Teacher will then divide students into groups to complete Heat transfer stations. Students will rotate through the stations that represent radiation, conduction and convection. Students will remain in stations for 15-20 minutes to complete tasks. Have students share out learning from the three stations. After rotations, the teacher will review the three heat transfers

 On the Smartboard, pull the following clip and play.  Radiation, Conduction, Convection song 

Step 3  Students will create a foldable with the three types of heat transfers. Students will need to place the name of the type of heat transfer, a definition and illustration for each transfer.
